Relative density of the vapour/air-mixture at 20°C (air = 1): []

 

Expl. A mixture consisting of vapour and air is present above liquids (and solids) that are in contact with the open air. The density of this mixture relative to the surrounding pure air at 20°C, is important to the behaviour of this mixture. At values >= 1.1 the mixture may travel along the ground and may accumulate in depressions. At values between 0.9 and 1.1 fast mixing with the surrounding air may be expected.

 

Ind. Skip if the substance is a gas or has a boiling point >=350°C. Round to 0.01 for values between 0.9 and 1.1; round other values to 0.1.

12701000

Flash point:                       []°C

 

Expl. A common definition of the flash point is: 'the lowest temperature at atmospheric pressure (101.3 kPa) at which a liquid gives off so much combustible vapour at the liquid surface that this vapour, when mixed intimately with air, can be ignited by a flame or spark.'  Flash points are also important characteristics of volatile solids such as benzoic acid and camphor. Although this definition of the concept flash point is unambiguous, its determination in actual practice meets with so many difficulties that it has been found necessary to specify the measurement procedures used for obtaining flash point values. Also, different authors may give different values as a result of impurities. When the exact value of the flash point is important in practice, it is best determined on the technical product at hand. The literature values have not always been determined according to one of the 'authorized' methods; the flash points quoted may differ from the values obtained by statutory methods. For safety reasons, the lowest value mentioned in authoritative references has been chosen. The addition 'o.c.' (open cup) or 'c.c.' (closed cup) indicates the determination method.

 

Ind. Preference should be given to closed cup values, if available, otherwise open cup values can be used. Round off to the nearest degree Celsius and add 'c.c.' or 'o.c.'. State 'none' if the flash point cannot be determined although explosion limits are given. State 'see Notes' if no flash point in literature can be found although the substance is combustible; combine with 24213. Skip if the substance is not combustible. See 12704 for flammable gases.

Flash point:                       []

 

Expl. A common definition of the flash point is: 'the lowest temperature at atmospheric pressure (101.3 kPa) at which a liquid gives off so much combustible vapour at the liquid surface that this vapour, when mixed intimately with air, can be ignited by a flame or spark.'  Flash points are also important characteristics of volatile solids such as benzoic acid and camphor.

Auto-ignition temperature:         []°C

 

Expl. A common definition of the auto-ignition temperature is: 'the lowest temperature at which a substance ignites spontaneously in contact with air and at which the combustion continues without there being a source of ignition (flame or spark).' The auto-ignition temperature depends not only on the properties of the substance but also on the dimensions, shape, nature of the contact material, and many other factors. In cases where the literature gives different values the lowest has been chosen. The auto-ignition temperature is important for the selection of electrical apparatus used in areas where explosive vapour/air mixtures may be present.

 

Ind. Round off to the nearest degree Celsius.

12710000

Explosive limits, vol% in air:     []

 

Expl. The explosive limits are the range in which a mixture of a vapour, gas, mist, or powder with air can catch fire or explode when ignited. The explosive limits of gases and vapours in air are given in percentage by volume. Vapour pressure, flash point, and lower explosive limit are interrelated. The explosive limits of powders depend on the size of the particles. Usually the explosive limits of powders range from about 0.04 to several kg/cubic meter.

 

Ind. The upper and lower explosive limits should be given, rounded off to 0.1%, separated by a 'hyphen'. Use '?' if the upper value is unknown.

 

If the substance is combustible but explosive limits are not known and the (estimated) flash point <=61°C: add 'see Notes' and also use 24215.

 

If the (estimated) flash point >61°C or the flash point cannot be estimated: do not use this phrase. If the substance is a powder, forming explosive mixtures with known limit values, these could be mentioned in Notes.

12713000

Minimum ignition energy (NOT on card): []mJ

 

Ind. A list of minimum ignition energy values taken from the literature is given in Appendix 3. This value has to be used in determining the possible selection of 15213.

12716000

Electrical conductivity (NOT on card): []pS/m

 

Apply to liquids (including liquid compressed gases). The electrical conductivity of a liquid is used for possible selection of 13221, 15207 and 15209. Electrical conductivity values found in the literature may be given in other units:

 

- S/m:  multiply by 1,000,000,000,000 to get pS/m

 

- Mho/cm:  multiply by 100,000,000,000,000

 

(Note: Mho = reciprocal Ohm).

 

As electrical conductivity is not highly dependant on temperature, values determined between 15 and 25°C can be used.

Octanol/water partition coefficient as log Pow: []

 

Expl. The octanol/water partition coefficient of a substance is useful as a means to predict soil adsorption, biological uptake, lipophilic storage, and bioconcentration, and is defined as the ratio of the concentration of a substance in octanol and water. For convenience, the logarithm of the Pow is used.

 

Ind. Values determined at about 20°C and 1 atmosphere should be given. Many log Pow values can be found in the Handbook of Environmental Data on Organic Chemicals, K. Verschueren. (1983), van Nostrand Reinhold; or in Leo, A., Hansch, C., and Elkins, D. (1971), Partition coefficients and their uses. Chemical Reviews, 71(6), 525-616.

As a result of flow, agitation, etc., electrostatic charges can be generated.

 

Expl. Electrostatic charges can be generated by the pumping, stirring, filtration, etc., of liquids having a conductivity lower than 10 000 pS/m. This occurs more readily when the liquids contain other liquids, gases, or solid particles (e.g., mixtures, suspensions). Equipment such as pumps, drums, piping, etc., become electrically charged and may make sparks when discharging to 'earth'. This may cause explosion of flammable vapour/air mixtures. A suitable remedy is to ground the conducting parts of such equipment.

 

In some cases of mist and dust explosions, it has also been assumed that static discharge has been the ignition source. In contrast to liquids, the conductivity of dust particles or droplets in dust clouds or mists is of little or no significance in the charge-generating capacity.

 

Ind. If a liquid (including liquefied compressed gas) with conductivity lower than 10 000 pS/m.

Dust explosion possible if in powder or granular form, mixed with air.

 

Expl. This is applicable to combustible substances which have the form of a powder or fine granules (diameter smaller than 0.5 mm). When well mixed with air, a substance in this form may deflagrate on ignition, even when somewhat humid. In a confined space, the deflagration may turn into an explosion. These dust explosions may be violent.

 

Ind. Applies if the substance is combustible and in the form of powder or granules with diameters smaller than 0.5 mm. Do not use this phrase if the literature contains evidence that when the substance is dispersed in air, it cannot be ignited.

On combustion, forms [].

 

Expl. This phrase mentions important products of combustion. These substances may, in themselves, cause e.g. health hazards. The combustion of nearly all organic substances causes the formation of toxic gases, including carbon monoxide (CO). On these ICSCs, the formation of CO is mentioned if it constitutes a predominant part of the combustion products.

 

Ind. Complete with toxic/caustic/acid/irritant/combustible/flammable/gas/vapour/mists/ fumes/solid and, if known, with the name of combustion product(s) between parentheses. In general combustion often produces a mixture of undefined toxic gases and CO; therefore 'toxic gases' may suffices. With aromatic and hetero-aromatic compounds the formation of CO is so predominant that it should be mentioned. See also for reference to other ICSCs. An example could be: On combustion, forms toxic gas including nitrogen oxides. Use one of the series 13341/13357 for more complicated cases.

The substance is a strong oxidant and reacts []with combustible and reducing materials[].

 

Ind. After 'reacts' the word 'violently' can be entered. The phrase can be completed by mentioning examples/special conditions. Strong oxidants are substances which readily respond to the potassium iodide I test by releasing iodine:

 

- Water-soluble substances: dissolve in a little water and adjust to pH 4-5, unless already acidic. Add a drop of the solution to 1 ml of a fresh 10% aqueous potassium iodide (KI) solution.

 

- Water-insoluble substances: add 0.1 g to 1 ml of a 10% solution of potassium iodide in acetic acid. A substance is also regarded as a strong oxidant if, when mixed with cellulose, the burning rate of the mixture equals or exceeds that of a mixture of barium nitrate and cellulose. This test is described in the Official Journal of the European Communities, L251, 19.9.1984.

The substance is a strong acid, it reacts violently with bases and is corrosive[].

 

Expl. Acids and bases are substances of mutually antagonistic character. Instead of 'bases', the terms 'alkaline' or 'caustic' substance are sometimes used. Both strong acids and bases are corrosive (mordant) to the skin and eyes. This property is generally known for acids, but the bases are just as dangerous in particular to the eyes. Strong acids and bases often react violently with other substances and attack many metals. Medium strong acids and bases are less dangerous but should not be handled carelessly. The terms strong acid applies to the well-known chemically strong acids (almost totally dissociating in water), including borderline cases with pH < 0.2.

 

Ind. Use for liquid acids with pH <= 0.2; use 13368 for solid salts which hydrolyze in water to acids. For calculation of the pH: See Appendix 4. The pH is for the saturated solution in water at 20°C, with a maximum of 10 molar. This phrase can be completed with indications of the materials towards which this strong acid is corrosive, as their corrosivities are not generally known. If hydrogen is evolved, mention this with the addition 'forming flammable/explosive gas (hydrogen - see ICSC0001)'.

OCCUPATIONAL EXPOSURE LIMITS (OELs):

 

Expl. Occupational Exposure Limits (OELs, TLVs values, etc.) can in general be described as limits for airborne concentrations of substances, which it is believed do not cause health effects to nearly all workers exposed day after day to those substances during their working lives. Some countries have OELs which originate from the list of Threshold Limit Values (TLVs) published each year by the American Conference of Governmental Industrial Hygienists (ACGIH). Other countries have OELs which are based on principles they have developed themselves. On the ICSCs, the OEL values of ACGIH are given. If a value from some other list was used, the source and year would be indicated. For the interpretation of national OELs or TLVs values, the original references should be consulted. If an OEL value has not been established this will be indicated. This does not mean that the substance should be considered as being non harmful to man; there are many thousands of substances widely used on an industrial scale, but OELs have been set for only about 800 of them.

 

Limits are intended for the use in the practice of industrial hygiene as guidelines or recommendations in the control of potential workplace health hazard. Three categories of TLVs are specified by ACGIH: Threshold Limit Value-Time Weighted Average (TLV-TWA), Threshold Limit Value-Short Term Exposure Limit (TLV-STEL), and Threshold Limit Value-Ceiling (TLV-C).

 

MAK (Maximale Arbeitsplatzkonzentrationen) are the official OELs in Germany. They will be updated every year and published by the Deutsche Forschungsgemeinschaft, Verlag Chemie, Weinheim.

 

N.B.: as the value on the ICSC may have been updated since the publication of the ICSC, always consult the latest official list in your country.

13401000

Simple asphyxiant

 

Expl. A number of gases and vapours, when present in high concentrations in air, act primarily as simple asphyxiant without other significant physiologic effects. The limiting factor is the available oxygen. The minimal oxygen content should be 18% by volume under normal atmospheric pressure (equivalent to a partial pressure of oxygen =135 torr =18.0 kPa). Atmospheres deficient in oxygen do not provide adequate warning and most simple asphyxiants are odourless. Several simple asphyxiants present an explosion hazard.

13410050

as TWA

 

Expl. Threshold Limit Value-Time Weighted Average is the time weighted average concentration for a conventional 8-hour workday and a 40-hour workweek, to which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse effect.

13410060

as STEL

 

Expl. Threshold Limit Value-Short Term Exposure Limit is the concentration to which it is believed that worker can be exposed continuously for a short period of time without suffering from

 

1) irritation,

 

2) chronic or irreversible damage, or

 

3) narcosis of sufficient degree to increase the likelihood of accidental injury, impair self-rescue or materially reduce work efficiency,

 

and provided that the daily TLV-TWA is not exceeded. It is not a separate independent exposure limit; rather, it supplements the time-weighted average (TWA) limit where there are recognized acute effects from a substance whose toxic effects are primarily of chronic nature. STELs are recommended only where toxic effects have been reported from high short-term exposures in either humans or animals. A STEL is defined as a 15-minute TWA exposure which should not be exceeded at any time during the a workday even if 8-hour TWA is within the TLV-TWA. Exposure above TLV-TWA up to STEL should not be longer than 15 minutes and should not occur more than four times per day. There should be at least 60 minutes between successive exposures in this range. An averaging period other than 15 minutes may be recommended when this is warranted by observed biological effects.

13410070

(Ceiling value)

 

Expl. The Threshold Limit Value-Ceiling is the concentration that should not be exceeded during any part of the working exposure.

 

In conventional industrial hygiene practice if instantaneous monitoring is not feasible, then the TLV-C can be assessed by sampling over a period that should not exceed 15 minutes, except for those substances that may cause immediate irritation when exposures are short.

 

For some substances, e.g., irritant gases, only one category, the TLV-Ceiling, may be relevant. For other substances, one or two categories may be relevant, depending upon their physiologic action. It is important to observe that if any one of these types of TLVs is exceeded, a potential hazard from that substance is presumed to exist.

 

The Chemical Substances TLV Committee holds the opinion that TLVs are based on physical irritation should be considered no less binding than those based on physical impairment. There is increasing evidence that physical irritation may initiate, promote, or accelerate physical impairment through interaction with other chemical or biological agents.

13410080

(skin)

 

Expl. Listed substances followed by the designation 'skin' refer to the potential significant contribution to the overall exposure by the cutaneous route, including mucous membranes and eyes, either by contact with vapour, or, of probable greater significance, by direct skin contact with the substance. Vehicles present in solutions or mixtures can also significantly enhance the potential skin absorption. It should be noted that while some materials are capable of causing irritation, dermatitis, and sensitization in workers, these properties are not considered relevant when assigning a skin notation. It should be noted, however, that the development of a dermatological condition can significantly affect the dermal absorption.

Expl. The note 'BEI' is listed when BEI is also recommended for the substance. Biological monitoring should be instituted for such substances to evaluate the total exposure from all sources, including dermal, ingestion, or non-occupational.

13410150

SEN

 

Expl. Listed substances followed by the designation 'SEN' refer for the confirmed potential for worker sensitization as result of dermal contact and/or inhalation exposure, based on the weight of scientific evidence. Lack of the sensitizer notation does not necessarily mean that the substance is not a sensitizer.

13410160

Intended change

 

Expl. These substances with their corresponding values and notations, comprise those for which a limit has been proposed for the first time or for which a change in the Adopted listing has been proposed. In each case, the proposed values should be considered trial values for the year following ratification by ACGIH Board of Directors. If, during the year, no evidence comes to light that questions the appropriateness of these proposals, the values will be reconsidered for adoption as TLVs. Documentation is available for each of these substances and their proposed values.

13410170

[(ACGIH 200#)].

13411000

Quick decomposition in moist air results in [] exposure.

 

Expl. Some substances on contact with water or moist air will rapidly form very toxic and/or corrosive gases (e.g. HCl, H2S, PH3, SO2, NH3, HCN, HBr, HF, Br2, H2SO4, Cl2, HI). The risk will depend on the severity of the effect and on the evolution rate of the gas formed. By giving the OEL of this toxic/corrosive gas as a product of contact with moist air, attention will be drawn so that the risk will not be underestimated.

 

Ind. Apply 13411 with the name of the toxic/corrosive gas formed, followed by the OEL of this gas, if:

 

- this gas is reported in the section 'Chemical dangers' under 'react with moist air'

 

- the toxic effects reported by inhalation are the effects primarily due to the gas emitted

 

- the OEL of the gas can be reasonably reached in less than 8 hours

13420000

Other OEL values (NOT on card): []

 

Expl. See expl. 13400. In (name country) national OELs are set by (name of national authority). The meaning of these OELs is defined as follows: ... Further information can be found in ...

 

Ind. All relevant and available OEL values for the substance in question as well as the ACGIH values should be mentioned on the Card matrix, e.g., those from the International Register of Potentially Toxic Chemicals (IRPTC) Legal File. The Peer-Review Committee will decide which OEL value will be printed on the ICSC. On an ICSC for a specific country, the national OEL value, if present, will have preference, using the relevant abbreviations. Text changes in the User's Guide should be applied if necessary to all phrases in which the generally applied abbreviation "OEL" has been used.

 

N.B.: It is assumed that values in the applied OEL system are based on OEL/TWA values of 8 hours a day, more or less conforming to the ACGIH system. It is also assumed that this system has values for short-term (maximum 15 minutes) exposure comparable with the STELs of the ACGIH. In this Guide these short-term OELs are denoted as OEL/ST values. The RIR index used later on (see Appendix 5.) has been developed from an OEL system on the principle of avoiding adverse effects as e.g., in the ACGIH system.

Carcinogen category: []

 

Expl. The following criteria have been followed to assign carcinogenic substances to 5 different categories:

 

1. Substances that cause cancer in man and can be assumed to make a significant contribution to cancer risk.

 

2. Substances that are considered to be carcinogenic for man because sufficient data from long-term animal studies or limited evidence from animal studies substantiated by evidence from epidemiological studies indicate that they can make a significant contribution to cancer risk.

 

3. Substances that cause concern that they could be carcinogenic for man but cannot be assessed conclusively because of lack of data. The classification in category 3 is provisional.

 

3A. Substances for which the criteria for classification in category 4 or 5 are fulfilled but for which the database is insufficient for the establishment of a MAK value.

 

3B. Substances for which in vitro or animal studies have yielded evidence of carcinogenic effects that is not sufficient for classification of the substance in one of the other categories. A MAK or BAT value can be established provided no genotoxic effects have been detected.

 

4. Substances with carcinogenic potential for which genotoxicity plays no or at most a minor part. No contribution to human cancer risk is expected provided the MAK value is observed.

 

5. Substances with carcinogenic and genotoxic effects, the potency of which is considered to be so low that, provided the MAK and BAT values are observed, no significant contribution to human cancer risk is to be expected.

 

Ind. Use according to the latest available version of the DFG publication.

2. Germ cell mutagens, which have been shown to increase the mutant frequency in the progeny of exposed mammals.

 

3A. Substances, which have been shown to induce genetic damage in germ cells of human or animals, or which produce mutagenic effects in somatic cells of mammals in vivo and have been shown to reach the germ cells in an active form.

 

3B. Substances which are suspected of being germ cell mutagens because of their genotoxic effects in mammalian somatic cells in vivo; in exceptional cases, substances for which there are no in vivo data but which are clearly mutagenic in vivo and structurally related to known in vivo mutagens.

 

4. Not applicable. Category 4 carcinogenic substances are those with non-genotoxic mechanisms of action.

 

5. Germ cell mutagens, the potency of which is considered to be so low that, provided the MAK value is observed, their contribution to generic risk for man is expected not to be significant.

 

Ind. Use according to the latest available version of the DFG publication.

13428040

Pregnancy risk group: []

 

Expl. The categorization of the substances according to their prenatal toxicity has been established as follows:

 

Group A. A risk of damage to the embryo or foetus has been unequivocally demonstrated. Exposure of pregnant women can lead to damage the developing organism even when MAK and BAT values are observed.

 

Group B. Currently available information indicates that a risk of damage to the embryo or foetus must be considered to be probable. Damage to the developing organism cannot be excluded when a pregnant women are exposed, even when MAK and BAT values are observed.

 

Group C. There is no reason to fear a risk of damage to the embryo or foetus when MAK and BAT values are observed.

 

Group D. Classification in one of the groups A-C is not yet possible because although the data available may indicate a trend they are not sufficient for a final evaluation.

 

IIc.   MAK value has been issued but no pregnancy risk group classification due to absence of adequate data.

 

Ind. Use according to the latest available version of the DFG publication.

ROUTES OF EXPOSURE:

13501000

The substance can be absorbed into the body []

 

Expl. Liquid and solid substances can be absorbed by swallowing, through the mucous membranes or the skin. Gas, vapour, mist, or finely dispersed solids will enter the body mainly through inhalation. This is the most frequent mode of exposure of substances in industrial situations. Liquid and solid substances can be absorbed by swallowing, through the mucous membranes or the skin. All of these subphrases can be completed with particulars; always close with a full stop (.).

 

Explanation of some terms:

 

Gas: a substance which at ambient temperature and pressure appears as a gas, meaning that the molecules of the substances travel freely in open space.

 

Vapour: the gas of a substance which is formed above a liquid or solid by evaporation. Evaporation means the release of molecules from the liquid or solid. Evaporation decreases with increasing boiling point and can generally be regarded as negligible if the boiling point exceeds 350°C.

 

Mist: a suspension of liquid particles in the air, formed by condensation of a vapour.

 

Fume: a suspension of liquid or solid particles in the air formed by condensation of vapours from heated metals or of vapours produced by a decomposition reaction. Moisture in the air often promotes the formation of mists and fumes by reactions with the vapours.

 

Dust-cloud: fine particles of powder of a solid substance, dispersed in the air.

 

Aerosol: a suspension of liquid or solid particles in the air. Mist, fume and dust-cloud are more or less covered by the term 'aerosol'.

 

Ind. The important routes of exposure resulting in absorption should be mentioned by making a choice out of one or more of the 13500 series according to human or acute experimental animal evidence. If no acute data is available in human or in experimental animals but the substance has systemic long term effect (cancer, reproduction effects, target organs systemic toxicity) then these data could be use to make a choice of phrases from the 13500 series.

 

For corrosives: If the substance is classified corrosive by specific route of exposure then select the corresponding phrase in section 13500. If the substance is corrosive to the skin, the respiratory tract and the digestive tract then select: 'Serious local effects by all routes of exposure'. Some exceptions such as phenol and hydrogen fluoride may exist to such approach for corrosive. Exception has to be documented carefully by the PI for peer-review meeting.

13502000

Expl. Liquid and solid substances can be absorbed by swallowing. This is the least frequent mode of exposure of substances in industrial situations. All of these sub phrases can be completed with particulars; always close with a full stop. See also 13501.

 

Ind. Apply if the substance has LD50 oral, mammals (rat)* according to GHS 3.1.2.3 or OECD guidelines <= 2000 mg/kg by weight.

 

Multiple exposure animal studies information or epidemiological studies indicating the substance may have long-term effect (cancer, reprotoxicity (F1, F2), specific target organ toxicity) through ingestion, or data derived from human ingestion accidental report could be use instead (Peer-review decision).

 

* LD values for rats are the primary choice but also other species could be used (Peer-review decision).

13513000

, also as a vapour!

 

Expl. Gas, vapour, mist, or finely dispersed solids will enter the body mainly through inhalation. This is the most frequent mode of exposure of substances in industrial situations. See also 13501.

 

Ind. Use in combination with 13509 for substances whose vapour can be absorbed through the skin and are hazardous. (Normally the skin notation refers to contact with the liquid or solid itself; the vapours of only a few liquids are known to be absorbed through the skin at a dangerous rate. Example: carbon disulfide.

INHALATION RISK:

 

Ind. Select only ONE phrase.

13601000

On loss of containment, a harmful concentration of this gas in the air will be reached very quickly[].

 

Expl. Many gases create a toxic atmosphere when released. This phrase is used when a harmful concentration of the substance in the atmosphere will be reached very quickly, and is based on a calculation involving the saturated vapour pressure.

 

Ind. In order to estimate the acute inhalation risk of a gas, the OEL/ST value has to be used; refer to 13400 (OELs) for details. If a substance has no OEL/ST value, the OEL/C or 3 x OEL/TWA is used. If OEL/TWA > 500 ppm, multiply by 2 instead of 3. In some cases, an estimated OEL/ST could be used, based on other toxicological data; see also Appendix 5. Use 13601 if gas with OEL/ST <= 5000 ppm or OEL/ST has not been established and cannot be estimated.

13601010

especially in confined spaces

13602000

On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.

 

Expl. Many gases, whilst in themselves only slightly or non-toxic, displace the air when released, especially in confined spaces. The resulting decrease in oxygen content can cause suffocation. A decrease of oxygen to less than 18% is enough to be dangerous.

 

Ind. In order to estimate the acute inhalation risk of a gas, the OEL/ST value has to be used; refer to 13400 (OELs) for details. If a substance has no OEL/ST value, the OEL/C or 3 x OEL/TWA must be used. If OEL/TWA > 500 ppm, multiply by 2 instead of 3. In some cases, an estimated OEL/ST could be used, based on other toxicological data; see also Appendix 5. Use 13602 if gas with OEL/ST > 5000 ppm or if the gas is known to be a simple asphyxiant (without other significant physiological effects), e.g., as indicated by the ACGIH (in all other cases use 13601).

 

24431

13603000

On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.

 

Expl. Liquid and liquefied gases evaporate very quickly and may create a toxic atmosphere or displace the air when released, especially in confined spaces. Even if only slightly or non-toxic, a resultant decrease in oxygen content can cause suffocation. A decrease of oxygen to less than 18% is enough to be dangerous.

 

Ind. In order to estimate the acute inhalation risk of a gas, the OEL/ST value has to be used; refer to 13400 (OELs) for details. If a substance has no OEL/ST value, the OEL/C or 3 x OEL/TWA must be used. If OEL/TWA > 500 ppm, multiply by 2 instead of 3. In some cases, an estimated OEL/ST could be used, based on other toxicological data; see also Appendix 5. Use for liquid and liquefied gas (11303).

EFFECTS OF SHORT-TERM EXPOSURE:

 

Expl. Short-term exposure generally refers to exposure up to one working day. In the description of effects of short-term exposure, the acute (minutes to hours) and latent (hours to days) effects are emphasized. Local effect: Relates to the effect of a substance on the part of the body which was exposed to the substance and which becomes manifest during exposure or within a short time of the contact.

 

Ind. Toxicological information should come from scientific literature preferably concerning man, or from animal studies that use guidelines like OECD or in accordance with generally accepted standards of good scientific practice at the time that the test was carried out. The chemical properties of the substance as assessed in series 13360/80 may be used. Although allowance should be made for exceptions, the following table could be used as a guide.

Inhalation of [] may cause lung oedema (see Notes).

 

Expl. Some chemicals can cause damage deep in the lungs, inducing lung oedema (fluid in the lungs). This effect may be delayed up to 24 hours after exposure. The patient should have complete rest (preferably in semi-recumbent posture) and must be kept under medical observation (even if symptoms have yet to manifest themselves). The doctor (or person authorized by him/her) may consider administration of an inhalation therapy. With all substances which may cause lung oedema, this warning has to be included in NOTES (e.g., 24201). Shortness of breath can sometimes originate from different causes such as an oxygen deficiency or asthma, without lung oedema developing.

 

Ind. Apply to substances where there is good literature evidence that inhalation of the substance can cause lung oedema (exposure to some non-corrosive substances may also result in lung oedema). Complete the first part of this phrase with 'this gas', 'vapour/mist/fume of this substance' or 'powder/dust of this substance', as appropriate. Combine the phrase with 24419 in NOTES.

Suffocation.

 

Expl. A number of gases and vapours, when present in high concentrations in air, act primarily as simple asphyxiant without other significant physiologic effects. The minimal oxygen content should be 18% by volume under normal atmospheric pressure. A decrease of oxygen to less than 18% is enough to be dangerous. Atmospheres deficient in oxygen do not provide adequate warning and most simple asphyxiants are odourless. Several simple asphyxiants present an explosion hazard.

13733000

If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.

 

Expl. Swallowing of some organic liquids with a low viscosity can cause coughing and vomiting, or impair deglutition.  As a consequence, liquid droplets can be aspirated into the lungs, with a risk of chemical pneumonitis.

 

Ind. Applies if an organic liquid with a viscosity < 7 mm2 /s or about 7 mm2 /s at 40°C (1 mm2 /s = 1 cSt; 1 centipoise = centistokes multiplied by density at given temperature).

, resulting in []

 

Expl. This phrase indicates if the substance can cause a systemic effect after exposure for a short period of time (up to one day). A systemic effect is one that occurs in a part of the body other than the point of contact, and indicates that the substance has been absorbed. The phrase indicates what organs or body systems may be affected and, if possible, what consequences this may have.

 

Ind. Use this phrase to indicate the effects only if it adds useful information to 13751 and there are good literature references. Only include effect that could be manifested after exposure to realistic levels. Do not include symptoms; these are described in 17100, 18100, and 19100.

 

Toxicological information should come from scientific literature preferably concerning man, or from animal studies that use guidelines like OECD or in accordance with generally accepted standards of good scientific practice of the time that the test was carried out.

 

'Respiratory failure' is the inability of the cardiac and pulmonary systems to maintain an adequate exchange of oxygen and carbon dioxide in the lungs. When this expression is chosen include one of the following in phrase 13751: heart, cardiovascular system, lungs or blood. 'Respiratory depression' is caused by the depression of the central nervous system, in which the respiration is slow or feeble failing to provide full ventilation and perfusion of the lung. When this expression is chosen include the following in phrase 13751: central nervous system.

the formation of methaemoglobin.

 

Expl. The blood contains a substance called haemoglobin which is important in the transport of oxygen from the lungs to all parts of the human body. Some substances can - when absorbed - alter haemoglobin into a form called methaemoglobin which cannot transport oxygen. Too much methaemoglobin in the blood will mean that the internal organs become starved of oxygen.

 

Ind. Apply for chemicals which can cause significant methaemoglobinaemia on short-term exposure. Chemicals that can generate methaemoglobin in vivo include nitrite and some aminophenols, N-hydroxyarylamines, aromatic amines, and arylnitro compounds. Combine with 13751 with 'blood' selected in the window of subphrases.

Cholinesterase inhibition[].

 

Expl. Much of the nervous system depends on a chemical neurotransmitter called acetylcholine, the action of which is controlled by an enzyme acetylcholinesterase. Some substances, such as organophosphorous and carbamate pesticides, can inhibit the activity of this enzyme. This results in accumulation of the active neurotransmitter and hyperactivity of the nerve pathways. Symptoms of acute poisoning can include irritability, tremors, convulsions, and possibly death, usually as a result of respiratory failure.

 

Ind. Apply for chemicals (carbamate or organophosphorous esters) which can cause significant cholinesterase inhibition. Combine with 13751 with 'nervous system'.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

13801000

Repeated or prolonged contact with skin may cause dermatitis[].

 

Expl. Repeated or prolonged exposure to a number of substances may lead to effects on the skin. This may take the form of inflammed or reddened skin, known as dermatitis.

 

Ind. Applies if positive human experience is available; refer to toxicological handbooks. May be completed with further short details; also see 13807.

13803000

Repeated or prolonged contact may cause skin sensitization[].

 

Expl. A contact sensitizer is a substance that will induce an allergic response following skin contact. People with an existing allergy should avoid contact with this substance.

 

Ind. Apply if there is evidence in humans that the substance can induce sensitization by skin contact in a substantial number of people, or where there are positive results from appropriate animal test. Evidence should include:

 

Positive data from patch testing, normally obtained in more than one dermatology clinic;

 

Epidemiological studies showing allergic contact dermatitis caused by the substance;

 

Positive data from appropriate animal tests;

 

Positive data from experimental studies in man.

 

Well documented episodes of allergic contact dermatitis, normally obtained in more than one dermatology clinic.

 

Evidence from animal studies is usually more reliable than evidence from human exposure. In cases where evidence is available from both sources, and there is a conflict in results, the quality and reliability of evidence from both sources must be assessed. Negative human data should not normally be used to negate positive results from animal studies.

 

In animal studies, when an adjuvant type method for skin sensitization is used, a response at least 30% of the animals is considered positive. For a non-adjuvant test method a response of at least 15% of the animals is considered positive.

 

A decision to use this phrase must be considered by the Peer-Review Committee.

13805000

Repeated or prolonged inhalation exposure may cause asthma[].

 

Expl. A respiratory sensitizer is a substance that will induce hypersensitivity of the airways following inhalation of the substance. This may result in rhinitis/conjuntivitis and alveolitis, or asthma. People with an existing allergy should avoid contact with this substance.

 

Ind.  Apply if there is evidence in humans that the substance can induce specific respiratory hypersensitivity, and/or where there are positive results from an appropriate animal test. Evidence will normally be based on human evidence and will generally be seen as asthma. Other hypersensitivity reactions such as rhinitis/conjunctivitis and alveolitis should also be considered. A decision on classification should take into account the size of the population exposed and the extent of the exposure. A decision to use this phrase must be considered by the Peer-Review Committee.

13807000

The liquid defats the skin[].

 

Expl. Many liquids have no direct effect on the skin and will not lead to an allergy, but will defat the skin upon prolonged or repeated contact. As a result, the skin may become rough, dry, and red. After the skin has been in frequent contact with, or is cleaned with, a defatting liquid, it should be washed off with water and soap and then treated with an ointment or cream.

 

Ind. Do not use if phrase 13801 has already been used. If both apply, preference should be given to 13801.

Lungs may be affected by repeated or prolonged exposure[].

 

Expl. The effects on the lungs include chronic bronchitis, lung fibrosis, etc. which only become manifest after some time of repeated or prolonged exposure. This phrase is used when the effects are only caused if relatively high concentrations of the substance are inhaled. Definition of long-term or repeated exposure: more extended exposure than short-term (i.e., more than one working day). In the description of effects of short term exposure, the acute (minute to hours) and latent (hours to days) effects should be emphasized, whereas in the description of the effects of long-term or repeated exposure the chronic and cumulative effects should be mentioned.

 

Ind. Applies when there is evidence of effects on the lungs (e.g., chronic bronchitis, lung fibrosis, etc.) which only become manifest after some time of repeated or prolonged exposure.

This substance is carcinogenic to humans.

 

Expl. A carcinogen is a substance which induces cancer or increases its incidence. Classification of a substance as posing a carcinogenic hazard is based on the inherent properties of the substance and does not provide information on the level of the human cancer risk which the use of this substance may represent.

 

This sentence indicates that there is sufficient evidence to support a causal association between the exposure to a substance and human cancer, according to criteria published by the International Agency for Research on Cancer (IARC) or outlined in the Globally Harmonised System (GHS) for Human Health and Environmental Effects of Chemical Substances. See Annex 9 and 10.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

 

Ind. Use phrase if it complies with criteria applicable to a placing as IARC Classification  Group 1 (Carcinogenic to humans) or GHS 1A (Known human carcinogen).

 

16207

13833000

This substance is probably carcinogenic to humans.

 

Expl. A carcinogen is a substance which induces cancer or increases its incidence. Classification of a substance as posing a carcinogenic hazard is based on the inherent properties of the substance and does not provide information on the level of the human cancer risk which the use of this substance may represent.

 

This sentence indicates that the evidence of a causal association between the exposure to a substance and human cancer is not sufficient, but it is strong enough to establish a probability, according to criteria published by the International Agency for Research on Cancer (IARC) or outlined in the Globally Harmonised System (GHS) for Human Health and Environmental Effects of Chemical Substances.

 

These data can be supported by mammalian experiments, since substances that have induced malignant tumours in well performed experimental studies in animals are also to be presumed to be human carcinogens unless there is strong evidence that the mechanism of tumour formation is not relevant for humans.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

This substance is possibly carcinogenic to humans.

 

Expl. A carcinogen is a substance which induces cancer or increases its incidence. Classification of a substance as posing a carcinogenic hazard is based on the inherent properties of the substance and does not provide information on the level of the human cancer risk which the use of this substance may represent.

 

Substances that have induced malignant tumours in well performed experimental studies in animals are also to be presumed to be human carcinogens unless there is strong evidence that the mechanism of tumour formation is not relevant for humans.

 

This sentence indicates that the evidence of a causal association between the exposure to a substance and human cancer is inadequate (or there are no human studies), but there is strong evidence from mammalian experiments for the presumption of a human carcinogenic hazard, according to criteria published by the International Agency for Research on Cancer (IARC) or outlined in the Globally Harmonised System (GHS) for Human Health and Environmental Effects of Chemical Substances.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

16207

13837000

Tumours have been detected in experimental animals but may not be relevant to humans.

 

Expl. A carcinogen is a substance which induces cancer or increases its incidence. Classification of a substance as posing a carcinogenic hazard is based on the inherent properties of the substance and does not provide information on the level of the human cancer risk which the use of this substance may represent.

 

This sentence is used when positive results from mammalian experiments are available in the published literature, but the tumours arise by mechanisms for which there is strong evidence that they may not occur in humans. Sometimes, an unrealistically high dose may be considered as part of such mechanism, e.g., leading to certain types of bladder tumours in rats.

 

A decision to use this phrase, or no phrase at all, must be a conclusion taken by the Peer-Review Committee.

 

Ind. Use this phrase if it complies with IARC Classification 3 (Unclassifiable as to carcinogenicity to humans) but differs from EC or other important classification system.

@May cause heritable genetic damage in humans.

 

Expl. The substance may cause mutations in the germ cells (ova or spermatozoa) of humans, which could be transmitted to the offspring. This phrase is used when there is clear evidence that the substance can cause heritable mutations, or the evidence is strong enough to suggest that the substance should be regarded as if it induces heritable mutations in germ cells.

 

Ind. The phrase was deleted in Hanover meeting 16.3.2001

 

Apply this phrase if there is sufficient evidence to establish a causal association between human exposure to the substance and heritable genetic damage, e.g., from human epidemiological studies, or when there is sufficient evidence to provide a strong presumption that human exposure to the substance may result in the development of heritable genetic damage, generally on the basis of

 

1) positive result(s) from in vivo heritable germ cell mutagenicity tests in mammals (e.g., specific locus test, heritable translocation, etc.),

 

2) positive result(s) from in vivo somatic cell mutagenicity in mammals in combination with evidence that the substance has potential to cause mutations to germ cells. This supporting evidence may, for example, be derived from mutagenicity/genotoxic tests in germ cells in vivo, or by demonstrating the ability of the substance or its metabolite(s) to interact with the genetic material of germ cell,

 

3) positive result(s) from tests showing mutagenic effects in the germ cells of humans, without demonstration of transmission to progeny; for example, an increase in the frequency of aneuploidy in sperm cells of exposed people.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

 

16207

13843000

@May cause genetic damage in humans.

 

Expl. There is some evidence to suggest that the substance may cause mutations in the germ cells (ova or spermatozoa) of humans.

 

Ind. The phrase was deleted in Hanover meeting 16.3.2001.

 

Apply this phrase if there is positive evidence obtained from experiments in mammals and/or in some cases in vitro experiments, obtained from

 

1) somatic cell mutagenicity test in vivo, in mammals,

 

2) other in vivo somatic cell genotoxicity tests which are to be supported by positive results from in vitro mutagenicity assays.

 

Chemicals which are positive in vitro mammalian mutagenicity assays, and which also show chemical structure activity relationship to known germ cell mutagens should also be considered.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

 

16207

13845000

May cause heritable genetic damage to human germ cells.

 

Expl. Since no chemical has been identified as including such damage, a more definitive phrase (i.e., Causes...) is not required. The substance may cause mutations in the germ cells (ova or spermatozoa) of humans, which could be transmitted to the offspring. This phrase is used when there is clear evidence that the substance can cause heritable mutations, or the evidence is strong enough for presumption that the substance should be regarded as if it induces heritable mutations in germ cells. Note that evidence restricted to the mutagenic effects in somatic cells, with no germ cell evidence, is subsumed by the carcinogenicity phrases (13831-13837).

 

Ind. There is either

 

a) strong evidence for a causal association between human exposure to the substance and heritable genetic damage, or,

 

b) sufficient evidence to provide a strong presumption that human exposure to the substance may result in development to heritable genetic damage, generally on the basis of appropriate mammalian studies, e.g., specific locus or heritable translocation tests and other relevant information, such as pharmacokinetic and tissue distribution studies in combination with somatic cell mutagenicity studies.

 

A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

Causes toxicity to human reproduction or development.

 

Expl. As effects upon men are more easily observed than effects upon women, it is considered that any attempt to distinguish between the sexes could be seriously misleading.

 

A decision to use of this phrase must be a conclusion taken by the Peer-Review Committee.

 

Ind. Use if human data are available which show that the substance impairs fertility in adults, results in embryotoxicity or fetotoxicity, or causes malformations, retarded development or functional deficiencies in the new born.

 

16205    16209

 

13853000 May cause toxicity to human reproduction or development.

 

Ind. This phrase can be used instead of phrase 13851 when the human evidence is weaker, but is supported by experimental evidence from exposed mammals. A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

 

16205    16209

13855000

Animal tests show that this substance possibly causes toxicity to human reproduction or development.

 

Expl. Causes developmental retardation (in utero or after birth) and embryolethality or malformations, in mammalian tests in the absence of severe maternal toxicity (i.e. substantial reduction in weight gain, persistent emesis, hypo- or hyper-activity or convulsions). There should be good evidence that the dose intervals in the experiment were sufficiently small to permit embryonic survival and the potential for any teratogenic effect to be expressed; if these conditions are not met, then consider  not using this phrase. Evidence of adverse effects usually come from teratogenicity, fertility, peri- and post-natal and multigeneration test designs. In addition to the information on reproductive capacity coming from the treatment of pregnant animals, other data may have to be considered by the investigators and the peer-review committee. These include :

 

1.  measure of spermatozoa count;

 

2.  measure of sperm motility;

 

3.  measure of sperm abnormalities;

 

4.  histology of the reproductive organs with a pathologist's evaluation that reproductive capacity has been impaired;

 

5.  dominant lethal effects in male or female animals (preimplantation loss, early death).

 

Reductions in 1, or 2, an increase in 3 or 5, or the record of an effect in 4, all could be interpreted as antifertility effects. Whether these effects are sufficient to trigger the use of a warning is a matter of judgement by the Peer-Review Committee.

 

Points to be considered in this judgement include:

 

1.  the severity of the effect;

 

2.  the dose level required to produce the effect;

 

3.  the relationship of this dose level to other indications of toxicity in the experimental animal;

 

4.  the relationship of the lowest effective dose level to the possible human dose levels (excluding catastrophic exposure);

 

5.  the reproducibility of the effect within the laboratory;

 

6.  the reproducibility of the effect in different laboratories.

 

Ind. A decision to use this phrase must be a conclusion taken by the Peer-Review Committee.

@Animal tests show that this substance possibly causes malformations in human babies.

 

Expl. Causes malformations at dose levels which do not cause severe maternal toxicity (i.e. substantial reduction in weight gain, persistent emesis, hypo- or hyper-activity, or convulsions). There may be accompanying embryolethality. It is desirable to have confirmatory data from independent experiments, particularly involving a second species.

- the substance is 'harmful' (to the aquatic environment) in 13902 or the substance is 'hazardous' (to the environment) in 13903 AND where there is evidence of bioaccumulation (13905 selected) or evidence that the substance is not readily degradable and has adverse effects.

 

A substance is considered as readily degradable if:

 

a) in 28-day studies, the following levels of degradation are achieved within 10 days of the start of degradation (this being the time when 10% of the substance has been degraded):

 

- in tests based upon dissolved organic carbon: 70%,

Fire: ACUTE HAZARDS.

14101000

Extremely flammable.

 

Expl. Relates to liquids that have a flash point < 0°C and an initial boiling point less or equal to 35°C, and to flammable gases, when liquefied.

 

Ind. Apply if flammable gas or liquid with flash point < 0°C and a boiling point (or in case of a boiling range, the initial boiling point) < 35°C, and to gases which are flammable in contact with air at ambient temperature and pressure. For explosive substances use 14121.

 

14201    22101

14103000

Highly flammable.

 

Expl. Solid substances and preparations which may readily catch fire after brief contact with a source of ignition and which continue to burn or to be consumed after the removal of the source of ignition.

 

Liquid substances having a flash point < 21°C, but which are not extremely flammable.

 

Substances which in contact with water or damp air evolve extremely flammable gases in dangerous quantities, at a minimum rate of one litre/kilogram/hour.

 

Substances which become hot and finally catch fire in contact with air at ambient temperature without any input of energy.

 

Ind. Apply if flammable gas or liquid with flash point > 0°C but < 21°C. Also to a solid which is spontaneously flammable in the air or which may readily catch fire after brief contact with a source of ignition and which continues to burn after the removal of the source of ignition.

 

For explosive substances use 14121. 'Readily catch fire' implies a burning time < 45 seconds for a 100 mm strip of heaped solid, ignited by a hot wire.

 

Also applies to organic peroxides and other solids apt to auto-oxidation with low ignition energy but that are not to be regarded as explosive (see 14121).

 

Low ignition energy can be interpreted as a self-accelerating decomposition temperature (SADT) less or equal to 35°C; a list of substances with SADT values can be found in the International Maritime Dangerous Goods Code, London.

 

When using the UN Transport classification for flammable solids, substances according to class 4.1 and 4.2 should be included for application of this phrase.

 

14201    22101

14105000

Flammable.

 

Expl. Relates to liquids and solids with flash point more or equal to 21 and < 61°C and to solids that continue to burn after removal of the source of ignition, but do not readily catch fire.

 

Ind. For explosive substances use 14121. Includes organic peroxides with relatively high ignition energy (i.e., SADT value > 35°C) and not regarded as explosive. Apply also if the flash point of a liquid is not available but is unlikely to exceed 61°C.

 

14201    22101

14107000

Combustible.

 

Expl. Relates to liquids and solids with flash point > 61°C, and to liquids and solids classified by UN as flammable even if there is no flash point available. Also applies to solids which, although difficult to ignite in normal air, are capable of supporting combustion if brought to a high temperature.

 

Ind. For explosive substances use 14121. Use for substances that are neither flammable (14101, 14103, and 14105 do not apply) nor explosive (14121). If both 14107 and 14115 apply, then use 14115.

 

14203    (22101)

14109000

Combustible under specific conditions.

 

Expl. Relates to liquids that have no flash point but form flammable vapour/air mixtures at elevated temperatures; explosive limits are often given. Also for substances (solids) that can only be burnt when subjected to high energy sources of ignition.

 

Ind. For explosive substances use 14121. Applies also to substances that are normally regarded as non-combustible but for which the phrases 'On combustion forming of....' or 'The substance decomposes on burning....' was used. Examples of liquids in this category: dichloromethane, trichloroethene, and 1,1,1-trichloroethane: they have no flash point but can form explosive vapour/air mixtures.

Not combustible.

 

Expl. Relates to substances that cannot (or only under very extreme conditions) be oxidized.

 

Ind. 'Very extreme conditions' are understood to be conditions which are not to be found generally in industry or normal laboratories. Also see 14113 and 14115.

14113000

Not combustible but enhances combustion of other substances.

 

Expl. Some non-combustible substances can give off oxygen which may enhance the combustion of other substances. Examples include: perchlorates, peroxides, and other oxidants.

 

Ind. Apply to inorganic chlorites, chlorates, perchlorates (and similar halogen compounds), permanganates, persulfates, some peroxides, nitrates, nitrites, and other non-combustible strong oxidants.

14115000

Not combustible but forms flammable gas on contact with water or damp air.

 

Ind. Substances such as Na or K that are neither flammable (14101,14103, and 14105 do not apply) nor explosive (14121), but that on contact with water or humid air evolve flammable gas in dangerous quantities (1 litre/kg/hour or more). If both 14107 AND 14115 apply, then use 14115.

Liquid formulations containing organic solvents may be flammable.

 

Expl. A substance, which may in itself be non-combustible, may commonly occur dissolved in a flammable solvent.

 

Ind. Apply to substances which in practice are often used in flammable commercial formulations.

 

(15109)    24437

14121000

Explosive.

 

Expl. Explosive substances can decompose violently when ignited by sparks or friction, causing a local temperature increase that triggers a very fast chain reaction. Although such a decomposition is often attended with fire, the reaction does not need an external source of oxygen, in contrast to an explosive combustion of a flammable vapour/air mixture. Explosives often contain in their molecules a relatively high oxygen content through which an internal combustion is possible. Substances with explosive characteristics can also be flammable. The term 'explosive' is used if the minimum ignition energy to trigger an explosion exceeds a certain standard or if the substance is definitely known to be explosive.

 

Ind. Applies if the substance when heated in a confined space explodes or appears to be more sensitive to shock or friction than m-dinitrobenzene. If test results or labelling indications are not available, the decision to use this phrase should be taken based on literature references. Use 15109 or 15111 to give further data.

Fire: EXTINGUISHING AGENTS.

 

Expl. To handle a chemical fire safely, specific training is necessary as each fire depends on the characteristics of the chemical, the location of the fire, other chemicals nearby, etc. Expert fire fighters must be trained in handling the types of fires at the facility, and planning drills must be carried out periodically. Management must ensure this is done or the threat from fire will be far greater. Moderate to large fires must be handled by expert fire fighters who must act with local authorities in judging whether the incident poses a threat to the surrounding community and therefore calls for an evacuation or calls for staying indoors with windows closed and ventilation off. Methods must be available for notifying the public without causing panic. This public participation must also be exercised periodically so that the residents near the facility know what needs to be done. A general rule for moderate to large fires is to shut off the supply of combustible substances if possible, obtain expert help and evacuate the area. For small fires, shut off supply of combustible substances, evacuate area, and extinguish if possible. Chemical workers can handle small fire themselves only when they are properly trained and have adequate equipment and supplies of materials such as compatible foams, etc. The selection of the fire extinguishing agents for an ICSC and the order in which they are listed is based on their applicability by laymen under various conditions as well as on their effectiveness. They are only intended for small fires. In case of moderate or large fires experts have to decide how to cope with the situation; under some circumstances it may be better to let the fire burn out instead of extinguishing it with water that afterwards could pollute the environment heavily with dissolved toxic substances (e.g., pesticides). In some instances it is stated which extinguisher must NOT be used, because a dangerous reaction may follow. In particular instances a special extinguishing agent is indicated. As the case may be, further information is given in Notes (e.g., 24101).

 

Ind. One or more fire extinguishing agents (general) should be mentioned (for tackling small fires) if the substance is (extremely/highly) flammable or combustible. No extinguishing agent should be mentioned for substances combustible only under specific conditions as the criteria used in this guide are not applicable to abnormal fire conditions. For these substances, 14351 or 14353 should normally be used. For flammable gases, normally the combination of 14301, 14313 and 14317 should be used. For all other flammable or combustible substances, use the following table for selection of the agents; if possible, put extinguishing agents in the order of preference. One of the series 14343/49 must be used to indicate 'forbidden' agents. Use 14303 and 14351 for non-combustible substances.

Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with []

 

Expl. This sentence is used for flammable gases. The best way to extinguish the fire is by shutting off the gas supply. If this is impossible, it is far better to let the fire burn itself out in a 'controlled' fashion rather than extinguish it.

 

Ind. Use for flammable gases, combined (usually) with 14313 and 14317.

14303000

water in large amounts,

 

Expl. The fire-fighting action of water mainly consists in cooling due to evaporation and exclusion of oxygen due to the formation of steam. Sometimes large amounts are needed. Also see expl. 14300.

 

The use of water jets in dealing with chemical fires is generally not recommended; a throw of 40 meters or more, and 1000 litres per minute is essential because of the risks created by the uncontrolled spreading of the chemicals, particularly corrosive, highly toxic, or environmentally sensitive material, thus increasing the hazard to emergency workers or passers by.

 

Water should not be applied on chemicals which react violently with water, without the approval of an expert. Many chemicals will react with water with a varying degree of violence.

 

Substances that are carried hot to maintain the solid as a melt or in solution, and would therefore be expected to rapidly solidify on cooling, should not be subjected to the application of considerable quantities of water unless this is necessary to effect safe control. In these circumstances, a medium or fine spray should be used.

 

Ind. Consider not using for corrosive (UN class 8), highly toxic (UN class 6.1), or environmentally sensitive material (UN class 9).

 

For chemicals carried hot to maintain the solid as a melt or in solution, use 14305 [Fine] water spray.

 

Do not use if it reacts violently with water.

14305000

water spray,

 

Expl. In this way the water is distributed more effectively over the burning substance, thereby enhancing its cooling and sealing effect. Also see expl. 14300.

 

A typical spray branch will deliver a range of droplet size up to 100 micrometers (fine/mist), 100-500 micrometers (medium), and 1000 micrometers (coarse) at distances up to 30 meters.

 

Water should not be applied on chemicals which react violently with water, without the approval of an expert. Many chemicals will react with water with a varying degree of violence.

 

Substances that are carried hot to maintain the solid as a melt or in solution, and would therefore be expected to rapidly solidify on cooling, should not be subjected to the application of considerable quantities of water unless this is necessary to effect safe control. Normally, therefore, a medium or fine spray should be used rather than coarse spray.

 

Compressed and liquefied pressure gases are normally dealt with by dilution/dispersion. Water in the form of a medium-fine spray (mist) can usually be effective in knocking down leaking gas clouds, though care is necessary to avoid water going directly on to some liquid gas pools where a rapid boil-off may be undesirable e.g. insoluble, toxic or flammable gases.

 

Ind. Do not use if the substance reacts violently with water.

 

Consider 'Fine water spray' if any of the following apply:

 

1) It is a non-flammable gas.

 

2) It is carried as a hot liquid above 100°C and considerable amounts of water are NOT essential for safe or effective control.

 

3) It is a liquid which is non-combustible (flash point >= 93°C).

 

4) It is a liquid which is combustible (flash point <= 93°C) and an oxidiser (UN class 5 or sub-risk 5.1).

 

5) It is a liquid which is combustible (flash point <= 93°C), which is NOT an oxidiser (UN class 5 or sub-risk 5.1), and is > 10% miscible with water (combine with 14311).

 

6) It is a solid which is (or its aqueous solution. is) corrosive (UN class 8), toxic (UN class 6), or environmentally sensitive (UN class 9), and where considerable quantities of water are not required for safe or effective control.

 

7) It is a combustible (flash point <= 93°C) immiscible liquid with relative density >1.1 at 20°C.

 

Consider 'Coarse water spray' if any of the following apply:

 

1) It is a solid which is (or its aqueous solution is) NOT corrosive (UN class 8), toxic (UN class 6), or environmentally sensitive (UN class 9).

 

2) It is carried as a hot liquid above 100°C and considerable amounts of water are essential for the safe and effective control.

 

3) It is a solid which is (or its aqueous solution is) corrosive (UN class 8), toxic (UN class 6), or environmentally sensitive (UN class 9) BUT considerable quantities of water are essential for the safe or effective control (e.g. solids of class 5.1 or those with sub-risk 5.1).

@AFFF if available,

 

Expl. Abbreviation for Aqueous Film Forming Foam, a liquid which, when mixed with water, yields a foam or sealing film. For its extinguishing effect see 'foam'. Also see expl. 14300.

 

Water-based extinguishing media should not be used on chemicals which react violently with water, without the approval of an expert. Many chemicals will react with water with a varying degree of violence.

 

Ind. Do not use if it react violently with water.

 

Not to be used in the Cards (decision 6.10.2000)

14309000

Foam.

 

Expl. A physically produced foam is meant here. Its action consists in preventing heat transfer between the flame and the burning liquid, whereby evaporation is inhibited. Also see expl. 14300.

 

Generally used for flammable liquids which are lighter than water and less than 1% miscible with water. Foam is essential if the risk of spread of fire is to be avoided. Its use is even more desirable with liquids of low flash point.

 

Ind. Apply to flammable liquids which are less than 1% miscible with water and relative density less than or equal to 1.1 at 20°C. Particularly if the flash point is low. Apply also to combustible liquids (flash point <= 93°C) with miscibility 1-10% with water, and combine with 14311.

14311000

Alcohol-resistant foam.

 

Expl. Alcohols, ketones, and esters are capable of 'breaking up' many types of foam, causing loss of the extinguishing effect. Special foam grades have been developed which are more resistant to such decomposition. (AFFF/ATC is also meant here; ATC stands for Alcohol Type Concentrate). Also see expl. 14300.

 

Ind. Use for combustible liquids (flash point <= 93°C) that are more than 1% miscible with water (polar solvents). Liquids which react with water are considered as having a miscibility of 1-10% and should have 14309 and 14311.

14313000

Dry powder.

 

Expl. Many chemicals will react with water with a varying degree of violence. Those which are considered to warrant particular violence because of severe exothermic reaction causing hazard to emergency workers should be treated with dry powder. These are mainly powders on a bicarbonate base or on an ammonium phosphate base. The extinguishing action appears to consist of inhibiting the chain reactions which keep the fire burning; this phenomenon is called negative catalysis. These powders are also called 'dry chemical' or ‘dry agent’. Also see expl. 14300.

 

Ind. Applies if the application of water would increase the overall hazard.

 

Use if any of the following apply:

 

1) Substances of class 3, ADR in Item 21 (a) or (b) and UN2988, due to their reactivity with water to form dangerous decomposition products, particularly when burning.

 

2) Substances of class 4.2, ADR Items (a), except 11 (a), (i.e. metal powders & pyrophoric substances e.g. metal alkyls).

 

3) Substances of class 4.3, ADR or sub-risk 4.3, except UN2210, because of liberation of flammable gases when wet.

 

4) Substances of class 5.1, ADR Item 5

 

5) Substances of class 6.1, ADR Item 44

 

6) Substances of class 8, ADR in Items: 1 (a) excluding UN2240, 8 (a), 10 (b), 11 (b), 12 (a) or (b), 33 (a), 35 (b) excluding UN2798 and 2799, 36 (b), 37 (b), 71 a) or (b), 72 (a) or (b), due to their reactivity with water to form dangerous decomposition products.

14315000

@halons,

 

Expl. Halons are compounds of fluorine, chlorine, and/or bromine with hydrocarbons such as methane and ethane. More specifically, BCF and BTM are meant. The extinguishing action appears to consist of inhibiting the chain reactions which keep the fire burning; this phenomenon is called negative catalysis. Because of the environmental drawbacks (i.e., interference with the ozone layer in the atmosphere), halons should only be used in special situations. Therefore halons are in general not recommended on the ICSCs as fire extinguishing agents, except for those substances which can hardly be extinguished by other agents. Also see explanation 14300.

 

Ind. Not used in the cards (decision 6.10.2000).

14317000

16100000

Physical contact: ACUTE HAZARDS/SYMPTOMS.

 

Expl. For each of the routes of exposure (inhalation, skin, eyes, and ingestion), a brief survey is given of the principal perceptible symptoms (signs) which may result when contact with the substance exceeds a certain degree. Only symptoms due to an acute exposure to the substance are mentioned.

 

Ind. Do NOT mention more than 8 symptoms in each subsection. In general only symptoms from human experience should be mentioned. Symptoms established in animal tests should only be mentioned if they are important to the reader and possible (in the professional judgement of compiler) in humans; application of the symptoms has to be peer-reviewed. Place symptoms in sequence. This sequence should be based on the occurrence of the symptoms on increasing exposure. Use an alphabetical order if an occurrence sequence can not be given. Systemic symptoms should be mentioned in the subsection on the route of exposure. Example: a possible symptom of ingestion of thallium is 'loss of vision'. This should be mentioned in subsection 'Ingestion', NOT in 'Eyes'.

16101000

See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.

16102000

See NOTES.

16200000

Physical contact: PREVENTION.

 

Expl. The prevention of physical contact for every route of exposure is briefly described. In practice the safety officer or the occupational hygienist will recommend the most appropriate precautionary measures for a given situation in order to limit the exposure to the substance sufficiently. The necessary precautionary measures should be selected and built into any new process during the planning stages that precedes its introduction. Obviously, it is of prime importance to prevent contact with the substance as far as practicable by suitable design and operation of process installations. These criteria take precedence over the use of devices for personal protection. Any evaluation of a danger situation must take into account not only the toxicity of a substance but also the chance of exposure. The risk of exposure may depend on factors such as:

 

- physical properties, such as vapour pressure, rate of evaporation, boiling point, solubility, particle size in solid substances, etc.;

 

- efficiency of systems for local exhaust of noxious gases and vapours;

 

- shape and dimensions of the working area and the possibility of dust being spread by air streams. Rapid spreading causes danger to other people also present in the working area;

 

- other circumstances under which the substance is used.

 

Ind. In case data on toxicity and on hazards of a substance are not readily available, the compiler should take this into account in the selection of the phrases on prevention.

16201000

PREVENT DISPERSION OF DUST!

 

Expl. This recommendation concerns solids that may induce formation of powder or dust on handling and may cause serious adverse effects.

 

Ind. If 13618 is used, this applies in case of 'harmful' concentrations. If no OEL has been established, application of these phrases should be based on other toxicological data. In case data on toxicity and on hazards of a substance are not readily available, the compiler should take this into account in the selection of the phrases on prevention.

16203000

PREVENT GENERATION OF MISTS!

 

Expl. This recommendation concerns liquids with high boiling points that may induce formation of mists on handling and may cause serious adverse effects.

 

Ind. If 13617 is used, this applies for high boiling liquids. If no OEL has been established, application of these phrases should be based on other toxicological data.

16205000

STRICT HYGIENE!

 

Expl. Hygienic precautions should always be observed when handling chemicals. This extra warning is given when a substance is considered to be so dangerous that particular caution must be exercised.

 

Ind. The application of this phrase should be considered if the substance is:

 

- a gas with an OEL <= 10 ppm or a rat LC50 (< 4hr) <= 0.5 mg/l;

 

- a liquid or solid with a RIR >= 4000; or

 

- a solid (powder) with an OEL < 1 mg/m3 or a rat oral LD50 <= 25 mg/kg.

 

The possible effects should also be considered.

16207000

AVOID ALL CONTACT!

 

Expl. This warning is given only for highly dangerous substances. The symptoms may appear either immediately or after some time has passed.

 

Ind. Apply if the substance is:

 

- a very corrosive or easily sensitizing substance;

 

- carcinogenic to humans

 

- mutagenic to humans ; or

 

- one for which all contact should be avoided because of serious hazard of irreversible damage. 'Contact' is to be regarded as a short-time contact of the substance in its normal physical state with the skin or on the inhalation/ingestion of very small quantities.

16209000

AVOID EXPOSURE OF (PREGNANT) WOMEN!

 

Expl. This warning is given for substances which are toxic to the reproduction and/or with a teratogenic effect (i.e., causing injury or deformity in unborn children after absorption of the substance by the pregnant woman). Exposure of women in the child-bearing age of life and expectant mothers should be as low as achievable and in any case always below the teratogenic level. Women, prior to being required to handle such a substance, should be informed of the potential effect. When the substance is used, it is also desirable to first ask the occupational physician and/or the safety officer for advice as to whether and in what way the substance should be handled.

 

Ind. Applies to (suspected) teratogenic substances and to substances toxic to the reproduction.

16210000

AVOID EXPOSURE OF BREASTFEEDING WOMEN!

 

Ind. Use this phrase if there is evidence that the substance has been detected in the milk and the one phrases 13851-13855 has been selected. A decisions to use this phrase must be a conclusion taken by the Peer-Review Committee.

16211000

AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

 

Expl. It should be forbidden to assign tasks to teenagers and to children in which they can be exposed to dangerous substances, as they are far more sensitive to the impact of noxious chemicals than adults. This phrase should therefore be superfluous. Yet it has been used on the ICSCs of many substances as an extra warning to keep the substance out of the reach of teenagers and children.

 

Ind. Use this phrase

 

- if there are developmental effects

 

- if children are likely to be more sensitive

 

- if there are long term effects

 

- if there are hormonal effects

 

- if there are morphological effects as opposed to physiological effects

 

- pesticides that are harmful or toxic to health according to the criteria in GHS.

 

The use of this phrase should be decided by the Peer Review group.

16300000

Physical contact: FIRST AID.

 

Expl. To properly apply the recommended first aid measures, the reader is referred to an appropriate instruction manual. Persons who may be required to apply first aid should be trained and qualified.

16301000

IN ALL CASES CONSULT A DOCTOR!

 

Expl. As the substance can cause serious effects by all routes of exposure, a doctor should be consulted.

 

N.B.: Indications on other phrases regarding medical attention are given in the sub-sections Inhalation, Skin, Eyes, and Ingestion.

 

Ind. Apply if serious effect can occur by any route of exposure, phrase 17309, 18315, 20317 is selected, and there is justification to highlight medical consultation. Apply to extreme cases. Peer-review group decision needed.

 

17309    18315    20317

17100000

Inhalation: ACUTE HAZARDS/SYMPTOMS.

 

Expl. The symptoms on the ICSC are mentioned as far as possible in sequence of occurrence on increasing exposure. However, personal sensitivity and/or other influences may cause symptoms to appear in different order. For each routes of exposure (inhalation, skin, eyes, and ingestion), a brief survey is given of the principal perceptible symptoms (signs) which may result when contact with the substance exceeds a certain degree. Only symptoms due to an acute exposure to the substance are mentioned.

 

Ind. Do NOT mention more than 8 symptoms in each subsection. In general only symptoms from human experience should be mentioned. Symptoms established in animal tests should only be mentioned if they are important to the reader and possible (in the professional judgement of the compiler) in humans; application of the symptoms has to be peer-reviewed. List symptoms in sequence, if appropriate. This sequence should be based on the occurrence of the symptoms on increasing exposure. Use an alphabetical order if an occurrence sequence can not be given. Systemic symptoms should be mentioned in the subsection on the route of exposure. Example: a possible symptom of ingestion of thallium is 'loss of vision'. This should be mentioned in subsection 'Ingestion', NOT in 'Eyes'.

Inhalation: PREVENTION.

 

Expl. Recommendations for the prevention of inhalation of noxious substances are highly dependant on the circumstances under which the substance is used, including its physical state and form. Therefore only general recommendations are given.

 

Ind. Do NOT use combinations of the 17200 series; use 17211 or 17213 only in special cases, see indication 17211 and 17213. If the 17200 phrases are not applicable, then use a free phrase. Sometimes there is no inhalation risk whatever, for instance if the RIR < 1 or when dealing with solids (b.p. >= 350°C) in lumps. In these cases no phrase is used.

17201000

Ventilation.

 

Expl. This applies to liquids or solids that do not in general carry serious risks when their vapour is inhaled, i.e. substances for which the OEL will not be exceeded under normal operating conditions.

 

Ind. Applies if the RIR < 12 and the substance is not a powder. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase. Sometimes there is no inhalation risk whatever, for instance if the RIR < 1 or when dealing with solids (b.p. >= 350°C) in lumps. In these cases no phrase is used.

Ventilation (not if powder).

 

Expl. This applies to solids that do not in general carry serious risks when inhaled, i.e. substances for which the OEL will not be exceeded under normal operating conditions. The addition '(not if powder)' is used if the substance also comes as a powder, that easily could be scattered by air streams caused by a ventilation system. As the inhalation of a powdered substance, even when of relatively low toxicity, should be prevented, ventilation should not be used in those cases.

 

Ind. Applies if the RIR < 12 and exposure to the substance as a powder. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase. Sometimes there is no inhalation risk whatever, for instance if the RIR < 1 or when dealing with solids (b.p. >= 350°C) in lumps. In these cases no phrase is used.

17204000

Avoid inhalation of fine dust and mist.

17205000

Local exhaust or breathing protection.

 

Expl. This applies to solid substances that are normally handled as powder or crystals. Even when the crystals are relatively large a certain portion will be powdered by mutual friction. In those cases local exhaust should be considered as a means of inhalation protection in the first place. If in spite of local exhaust an adverse concentration of the substance in the air could occur, one should use respiratory protective equipment such as:

 

- fresh-air hoods or masks;

 

- filter respirators with adsorption cartridge or canister of the right type;

 

- particle dust respirators, if necessary combined with an adsorption cartridge.

 

For the selection of respiratory protective equipment always consult a safety officer or an occupational hygienist. Rules for the selection may differ by nation. Important points for all types of respiratory protective equipment are:

 

- choice of appropriate equipment;

 

- clear operating instructions;

 

- frequent checks on proper use; and

 

- for filters: observance of the guarantee period, their limited absorption capacity, and the concentration of oxygen in ambient air (it should be > 18%).

 

Ind. Applies for solids which can develop dust on handling. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase.

17206000

Local exhaust.

17207000

Ventilation, local exhaust, or breathing protection.

 

Expl. One of these measures has to be employed for a liquid or gas whose OEL can be exceeded under normal conditions. When using closed apparatus, ventilation may be adequate; in other cases local exhaust or respiratory protective equipment has to be used. N.B. Dust respirators are inappropriate and inadequate for the handling of aerosols and atomized liquids (e.g., in paint spraying).

 

Ind. Applies if the substance is a liquid or gas with a RIR >= 12. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase.

17209000

Ventilation (not if powder), local exhaust, or breathing protection.

 

Ind. Applies if the substance is a liquid or gas and also for solids with a RIR >= 12 which may come in dusting as well in non-dusting form. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase.

17211000

Breathing protection.

 

Ind. Normally this phrase should NOT be used. The application should be a Peer-Review decision based on arguments presented by the compiler. Do NOT use combinations of the 17200 series. If not applicable, use a free phrase.

17213000

Closed system and ventilation.

 

Expl. This phrase is to be used for those substance for which the inhalation hazard of vapour or dust is so high that the application is only acceptable in totally closed systems. Even then ventilation is necessary as minimal leakage could occur. When handling such substances (e.g., for internal transport) the containers should be of high quality and leak-proof.

 

Ind. Apply only to those few substances for which processing in a closed system is the only solution, e.g., IARC Class I carcinogens. Consider first the alternatives 17205/09 as detailed in their ind. and expl. ('Avoid contact' does not necessarily imply 'closed system'!) Do NOT use combinations of the 17200 series. If not applicable, use a free phrase.

Half-upright position.

 

Expl. This is important in those cases where inhalation of a severely irritating or a corrosive substance has led to shortness of breath or which is likely to cause lung oedema. This position is often the most comfortable for the patient.

 

Ind. Apply to substances likely to cause lung oedema.

17305000

Artificial respiration may be needed.

 

Expl. This applies to serious cases where the patient has stopped breathing altogether or nearly altogether. Artificial respiration is also indicated in cases of acute laboured breathing with a risk of suffocation. In many cases where the ICSC recommends artificial respiration, an obvious first choice would be to administer oxygen, but this form of treatment has been left out deliberately. The administration of oxygen, if carried out improperly, is sometimes more harmful than beneficial to the patient. It should therefore be administered exclusively by specially trained first aid and medical personnel or doctors. It is useful to have oxygen resuscitation apparatus available near to sites where the risk is high and where on-the-spot treatment could be given by properly qualified first aid personnel.

 

Ind. Applies when, based on collective information on the chemical and symptoms, respiratory distress might be expected. If an oxygen apparatus should be available when handling the concerning substance, then also use 24425.

17306000

No mouth-to-mouth artificial respiration.

18100000

Skin: ACUTE HAZARDS/SYMPTOMS.

 

Expl. A substance may produce acute symptoms when it comes in contact with the skin. Where a substance may be absorbed by the skin, consideration must be given to whether or not this constitutes an acute physical hazard. The degree of hazard following skin absorption depends chiefly on:

 

- the permeability of the skin;

 

- the duration of exposure;

 

- the concentration of the substance;

 

- the nature of the substance; and

 

- the properties of the solvent, if used.

 

Absorption may occur without visible symptoms! The symptoms on the ICSC are mentioned as far as possible in sequence of occurrence on increasing exposure. However, personal sensitivity and/or other influences may cause symptoms to appear in a different order. For each routes of exposure (inhalation, skin, eyes, and ingestion), a brief survey is given of the principal perceptible symptoms (signs) which may result when contact with the substance exceeds a certain degree. Only symptoms due to an acute exposure to the substance are mentioned.

 

Ind. Do NOT mention more than 8 symptoms in each subsection. In general only symptoms from human experience should be mentioned. Symptoms established in animal tests should only be mentioned if they are important to the reader and possible (in the professional judgement of the compiler) in humans; application of the symptoms has to be peer-reviewed. List symptoms in sequence, if appropriate. This sequence should be based on the occurrence of the symptoms on increasing exposure. Use an alphabetical order if an occurrence sequence can not be given. Systemic symptoms should be mentioned in the subsection on the route of exposure. Example: a possible symptom of ingestion of thallium is 'loss of vision'. This should be mentioned in subsection 'Ingestion', NOT in 'Eyes'.

18101000

[]

18102000

Easily absorbed.

 

Ind. Select if the skin absorption is the principal route of exposure.

18103000

MAY BE ABSORBED!

 

Ind. Applies if absorption (13503 or 13509) is to regarded as an acute hazard in peer-review; if the substance meets the criteria of dermal acute toxicity category 1 or 2 in GHS (dermal LD50<200 mg/kg, fatal/toxic in contact with skin) OR if it has serious long term systematic effects (cancer, reproductive toxicity) and has been shown to pass through skin in significant amounts. The decision to use this phrase is taken  by peer-review Committee.

Skin: PREVENTION.

18201000

Protective gloves.

 

Expl. In general it is necessary to use protective gloves when handling chemicals. With only a few substances that are physiologically regarded as harmless could one refrain from the use of gloves, provided the contact period is short. Extensive contact with these substances may cause mechanical damage (abrasion, cutting) to the skin; use of industrial gloves made of leather or woven textiles is recommended in these cases. In all other cases such industrial gloves may not protect the skin adequately and should not be used. To prevent injury to and/or absorption through the skin, gloves made of rubber or plastic impermeable to the substance in question should be used. For some chemicals however, a glove material that offers adequate protection is not yet available; such substances must therefore be handled only in effectively protected equipment (i.e., closed). As regards the choice of the glove material, the safety officer should be asked for advice. Refer also to special publications, e.g., Guidelines for Selection of Chemical Protective Clothing, published by the American Conference of Governmental Industrial Hygienists (ACGIH), Cincinnati (USA).

 

Ind. Applies to all substances with the exception of:

 

- solid substances which can be regarded as physiologically inert;

 

- liquids frequently handled at a temperature > 50°C;

 

- liquids frequently handled at a temperature < -30°C;

 

- liquids with a boiling point < 20°C; or

 

- liquefied gases in cylinders (13105).

18203000

Cold-insulating gloves.

 

Expl. These are recommended for prevention of frostbite in the handling of cold substances (e.g., compressed liquefied gases or liquids whose boiling point is below 0°C). If the substance can penetrate through the skin or damage it, a combination must be found with a rubber or plastic glove material which is sufficiently resistant to the substance.

 

Ind. Use this phrase for:

 

- liquids with a temperature < -30°C;

 

- liquids with a boiling point < 20°C; or

 

- liquefied gases in cylinders (13105).

18205000

Heat-insulating gloves.

 

Expl. These are recommended for prevention of burns in the handling of substances often handled at elevated temperature (e.g., molten sulfur). If the substance can penetrate through the skin or damage it, a combination must be found with a rubber or plastic glove material which is sufficiently resistant to the substance.

 

Ind. Use this phrase for liquids frequently handled at a temperature > 50°C.

18207000

Protective clothing.

 

Expl. The aim should be to adjust the working conditions so that normal working clothes, i.e., overalls with suitable gloves and boots, can be worn. In practice, however, this will not always be possible. The use of protective clothing is recommended when even occasional contact with a substance through the normal working clothes can have serious consequences. The safety officer should decide whether working conditions require the wearing of protective clothing and, if so, the type to be worn. Also see the Guidelines for Selection of Chemical Protective Clothing, published by the American Conference of Governmental Industrial Hygienists (ACGIH), Cincinnati (USA).

 

N.B.: Trousers should be worn over boots, not tucked in.

 

Ind. Applies to the following substances:

 

- liquids which cause skin burns, such as strong oxidants and concentrated strong acids and bases;

 

- substances which may cause sensitization; or

 

- substances whose absorption through the skin involves hazards.

18209000

18300000

Skin: FIRST AID.

18301000

Remove contaminated clothes.

 

Expl. Usually it makes sense to take off contaminated clothes and shoes as soon as possible to avoid further contact between them and the skin. It is better, however, to start with a rinse or a shower and to take off clothing during this treatment.

 

Ind.  Use with 18309, 18311 or 18313. Apply for gases or liquids with flash point between  0°C and 61°C, spontaneously flammable solids (such as organic peroxides) or which may readily catch fire after brief contact with a source of ignition and which continue to burn after the removal of the source of ignition.

 

Apply when criteria for GHS corrosive for skin (Category 1) is met, substances which have a skin notation in OELs or which are absorbed through the skin in harmful quantities according to literature references (LD50 dermal <= 2000 mg/kg by weight).

 

Apply when repeated or prolonged contact may cause skin sensitization.

 

Do not apply in case of thermal burning or frostbite because of the increased risk of infection when blisters burst.

18303000

ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.

 

Expl. In case of frostbite, do not remove clothing because of the increased risk of infection when blisters burst. Obviously, the contaminated clothes and skin must be rinsed with plenty of water.

 

Ind. Applies to substances that can cause frostbite, i.e., if 13741 or 13743 is used.

18305000

Rinse with plenty of water, do NOT remove clothes.

 

Expl. In case of burning or frostbite, do not remove clothing because of the increased risk of infection when blisters burst. Obviously, the contaminated clothes and skin must be rinsed with plenty of water.

 

Ind. To be used in special cases.

18307000

First rinse with plenty of water, then remove contaminated clothes and rinse again.

 

Expl. When the skin and clothing are heavily contaminated with strong oxidants or with strong reducing agents, the clothes could catch fire. In those cases it is preferable to rinse first with water or have a shower and only then remove contaminated clothes.

 

Ind. Applies if 13361 or 13363 is used.

18309000

Eyes: PREVENTION.

 

Expl. The type of eye protection to be used depends on both the substance to which one is exposed and on the work situation. More than one means of protection is sometimes mentioned. Contact lenses in general give no protection to the eyes in industrial situations. The recommendations on eye protection are the same whether or not contact lenses are worn. Contact lenses can cause extra risks; it is better to not use them at all but to wear safety spectacles with correcting lenses instead.

19201000

Safety spectacles

 

Expl. To be used for protection against liquid and/or solid substances that present little danger to eyes and skin upon occasional contact (apart from mechanical danger). The type with side shields is preferable. Attention should be given to the resistance of the materials of the spectacles to the substances which are to be handled. This applies also to other means of eye protection. The type of eye protection to be used depends on both the substance to which one is exposed and on the work situation. More than one means of protection is sometimes mentioned. Contact lenses in general give no protection to the eyes in industrial situations. The recommendations on eye protection are the same whether or not contact lenses are worn. Contact lenses can cause extra risks; it is better to not use them at all but to wear safety spectacles with correcting lenses instead.

 

Ind. This phrase can be combined with 19205 or 19207. This phrase should be applied to all substances that do not require more complete means of protection. Exceptions:

 

- solids which cannot easily be dispersed, e.g., pastes; or

 

- gases in cylinders which are in themselves not dangerous to the eyes.

19203000

Safety goggles

 

Expl. To be used for liquid and solid substances including fine powders that may endanger the eyes, but present little danger to the (facial) skin upon occasional contact. The type of eye protection to be used depends on both the substance to which one is exposed and on the work situation. More than one means of protection is sometimes mentioned. Contact lenses in general give no protection to the eyes in industrial situations. The recommendations on eye protection are the same whether or not contact lenses are worn. Contact lenses can cause extra risks; it is better to not use them at all but to wear safety spectacles with correcting lenses instead.

 

Ind. Applies if the substance is corrosive to the eyes but not to the skin (see 13705 and its alternatives), or if the substance occurs as a powder and is a nuisance to the eyes. This phrase can be combined with 19205 or 19207.

19205000

Face shield

 

Expl. To be used for liquid or non-dusting solid substances that are dangerous to both eyes and skin. The type of eye protection to be used depends on both the substance to which one is exposed and on the work situation. More than one means of protection is sometimes mentioned. Contact lenses in general give no protection to the eyes in industrial situations. The recommendations on eye protection are the same whether or not contact lenses are worn. Contact lenses can cause extra risks; it is better to not use them at all but to wear safety spectacles with correcting lenses instead.

 

N.B.: A face shield affords inadequate protection in situations where liquid droplets can splash up from below, for instance, when an object drops into a drum filled with the liquid.

 

Ind. Applies if the substance is corrosive to skin (see 13705 or its alternatives), or if an acute absorption hazard (18103), or if 11303 (liquefied gas) was used. This phrase can be combined with 19201 or 19203 by starting it with 'or'; without 'or' it can also be applied either alone or in combination with 19207.

19205010

or

19205020

and

19207000

eye protection in combination with breathing protection.

 

Expl. Depending on the work situation, this alternative to any of the preceding means of eye protection has to be used for substances that are both dangerous to the eyes AND:

 

- involve a great risk of inhalation of a harmful vapour concentration;

 

- inhalation of which in the form of a finely dispersed powder, such as in the event of dusting, should definitely be avoided; or

 

- must on no account be allowed to come into contact with the skin.

 

The combination may consist of:

 

- a fresh-air hood;

 

- a full-face respirator with either fresh-air supply or filter of the right class (powders) or type (vapours);

 

- a fresh-air helmet (for some solids only).

 

Ind. This phrase should be used for gases or liquids. Applies if the RIR > 4000 and any skin contact should be avoided; or inhalation of powder from the substance is not allowable, and any skin contact should be avoided.

19209000

eye protection in combination with breathing protection if powder.

 

Ind. This phrase should be used for solids which may come as a powder. Applies if RIR > 4000, and any skin contact should be avoided; or inhalation of powder from the substance is not allowable, and any skin contact should be avoided.

Ingestion: ACUTE SYMPTOMS.

 

Expl. Although it can be assumed that nobody will intentionally eat or drink chemicals, symptoms that result from this route of absorption, are listed as far as space permits or the hazard of a substance demands. In this connection, solids or liquids that stick to the skin (hands) or clothes are considered to be particularly dangerous. The symptoms are listed in order of occurrence on increasing exposure (use 20150). See explanation 16100.

 

Ind. This sub-section should only be used for liquids or solids (not gases) that are toxic or corrosive in relatively small amounts, for instance if:

 

- the rat oral LD50 < 2 g/kg,

 

- a strong or medium strong acid/base,

 

- a strong oxidant,

 

- the substance needs a T+, T, Xn, C, or O label conforming to the EC rules; or

Do not eat, drink, or smoke during work.

 

Expl. It is recommended that there should never be eating, drinking, or smoking during work. Although this recommendation could be considered to form a normal part of the general rules of conduct, it is mentioned on all ICSCs as an extra warning. In view of the great risk of food being contaminated during the handling of toxic powders or viscous toxic liquids, this warning applies especially to those substances.

20305000

Give a slurry of activated charcoal in water to drink.

 

Expl. Activated charcoal is used to prevent the absorption from gastrointestinal tract in case of potentially toxic amounts of chemical. Delay in the administration of activated charcoal impairs its efficiency and therefore it should be administered as soon as possible This means within one hour after ingestion, but the potential benefit after one hour cannot be excluded. Because ingested amount is usually unknown, activated charcoal doses should be high enough: for adults 25-100 g in glass of water is recommended. However, NEVER GIVE A DROWSY OR UNCONSCIOUS PATIENT ANYTHING TO DRINK!

 

Ind. Applies to substances which can be easily ingested at amounts producing severe intoxication. This means substances with an oral LD50 <200-300 mg/kg (about) and high amounts need not to be ingested to produce toxicity. Contraindications for the use of activated charcoal include unprotected airway (for example, resulting from lowering of consciousness) and situations in which its use increases the risk of aspiration (for example, liquid hydrocarbons). Charcoal should NOT be used for elemental metals, iron salts, lithium salts, ethanol, isopropanol, methanol, ethylene glycol, petroleum distillates with high aspiration potency, strong acids and alkali. Although activated charcoal may be less effective for cyanide salts, it may still be of benefit if administered immediately after the ingestion..

20307000

Induce vomiting (ONLY IN CONSCIOUS PERSONS!).

 

Expl. Inducing vomiting is dissuaded as a first aid measure because of the risk of aspiration of stomach contents. It is better to take the patient to a doctor who can decide on the necessity and method of emptying the stomach. This phrase will therefore only be applied in special cases. NEVER INDUCE VOMITING IN AN UNCONSCIOUS PERSON!

 

Ind. Apply to substances with an oral LD50 < 200 mg/kg combined with a high resorption rate, e.g., certain pesticides. In these cases the aspiration danger does not prevail. Do not use for corrosive or caustic substances and organic solvents of low viscosity.

20309000

Do NOT induce vomiting.

 

Expl. While inducing vomiting is dissuaded in general, this warning is given for corrosive or caustic substances and organic solvents of low viscosity. Corrosives and caustics cause extra harm to mucous membranes on vomiting, and solvents may cause chemical pneumonitis if aspirated.

 

Ind. Add systematically for all corrosive and severely irritating substances, and organic solvents of low viscosity, excluding very toxic substances.

¦    SPILLAGE DISPOSAL     ¦

 

Expl. The ICSC is limited to the handling of small to moderate sized spills. For larger spills, experts must be notified and actions must be taken such as evacuation or fire fighting. For extremely dangerous substances, any spill is dangerous enough for the chemical worker to call for expert help. In any case, personal safety equipment must be worn when such chemicals are spilled and evacuation is usually in order. The more dangerous a substance is, the more important it is to have an emergency plan available for large spills and to devise actions to be taken in the event of a sudden small or moderate leakage or discharge to the surroundings. Some means of limiting the effects of leakage are:

 

- facilities for collecting spilled liquid;

 

- sand or a suitable absorbing material for containment or absorption;

 

- provision to seal leaking drums; and

 

- provision to rinse away spilled substance (as far as allowed);

 

- ventilation.

 

In connection with this the following aids should be available at all times:

 

- personal protective equipment (goggles, face shields, special clothing, aprons, boots, gloves, respiratory protective equipment, etc.);

 

- collecting vessels (e.g., enclosing vessels);

 

- neutralizing agents; and

 

- sand or a suitable absorbing material.

 

Detailed disposal procedures are given in various handbooks on chemical safety detailed disposal.

 

When chemicals are used in the cleaning-up procedure, attention should be given to eventual disposal of the waste materials. The general measures for spillage disposal on the ICSC are intended to protect those who have to deal with a spill and to avoid environmental pollution. Concerning the latter, adaptations should be made so that directives on the ICSCs conform to the rules of national legislation, including possible incineration or other disposal of collected residues.

 

Ind. Read this instruction first! Select the phrases in this section in order:

 

1. Personal protection

 

2. Environmental precautions

 

3. Clean-up procedures

 

Disposal phrases are presented twice, first as phrase combinations and then as single phrases. Most liquids and solids conform to the specification of one or another of the groups A, B, and C that are listed below. Having determined in which group a  substance belongs one can use the fixed combination of disposal phrases appropriate to that group. If there is no fixed combination that applies to a particular substance the compiler should select the appropriate phrase(s). Ind. and expl. relative to the disposal phrases are provided only with the single phrases. Compilers using fixed combination phrases may need to refer to the single phrases when ind. and expl. are required to confirm the appropriateness of a combination. For disposal of gases see 21105, 21107, and 21241.

 

N.B.: The classification into the groups A, B, and C is based on generally accepted ideas on the prevention of water pollution.

 

Group A contains salts whose ions are fairly common in natural surface waters; group B contains those substances which in general cause little pollution and therefore could be drained in small amounts; group C contains substances which cause undesired pollution. If necessary the list of group C can be adapted to national legislation. After using the combination phrases, the single phrases should be gone through and be added as necessary. Give attention to special disposal phrases 21237/39/41/45.

 

Specification of the groups A, B, and C:

 

A: Inorganic salts, acids, and bases only containing one or more of the following: aluminium, ammonium, calcium, iron, magnesium, manganese, potassium or sodium; carbonate, chloride, nitrate, phosphate (ortho), silicate, or sulfate.

 

A1: Solid: neutral or weak or medium strong acid or base.

 

A2: Solid: strong acid or base.

 

A3: Liquid: neutral or weak acid or base.

 

A4: Liquid: medium or strong acid or base.

 

B:  Liquids (B1) and solids (B2) with a solubility in water > 10 g/100 ml and with flash point > 0°C, and not reacting spontaneously with water to produce toxic or flammable vapours or gases, and not belonging to group A or C.

 

C:  Liquids (C1) and solids (C2) which do not meet the specification of group A or B, or are mentioned in the following lists:

 

Substances containing any of the following elements: antimony, arsenic, barium, beryllium, boron, cadmium, chromium, cobalt, copper, lead, mercury, molybdenum, nickel, selenium, tellurium, thallium, tin, titanium, uranium, vanadium, zinc.

 

Substances belonging to one of the following categories:

 

-acid halides

 

-amides

 

-aromatic polycyclic compounds

 

-biocides and pesticides

 

-carbides

 

-carcinogens, human and animal (including asbestos)

 

-halogens and their organic compounds (except bromide, chloride and iodide salts)

 

-hydrogen cyanide, hydrogen fluoride, hydrogen selenide and hydrogen sulfide (all of their solutions and salts)

 

-mercaptans

 

-nitrites and nitrides

 

-nitrogen-containing organic compounds (except amines and ammonium salts)

 

-oils (mineral)

 

-phosphorus and organic phosphorus compounds

 

-peracids, peroxides, persalts

 

-phenols and phenol compounds

 

-silanes (halogenated)

 

-silicon-containing organic compounds, silicones included

 

-sulfur-containing organic compounds (except sulfates and sulfites)

 

-all persistent substances which could accumulate in animals or plants.

 

N.B.: Sometimes a liquid C can be transferred to group B by a simple treatment of the spillage; in such cases apply 21207, 21209 and 21227.

 

All phrases with '[]containers' can be completed with material specification. Use this possibility only when strictly necessary.

21101000

Evacuate danger area[]!

 

Expl. The immediate area of an incident is that area of approximately 100 meters radius in which the emergency services operate. Consideration may be given to warning people nearby to stay indoors with doors and windows closed. Evacuation would be considered when there is a threat to people in immediate danger.

 

Ind. In general, 21101 and 21103 are used in combination although a situation could occur when only one of them is selected. Apply 21101 if:

 

- a flammable gas with relative density to air >= 0.9;

 

- a toxic gas with a rat LC50 (4 hr) <= 2 mg/l (T-label according to EC rules);

- a flammable gas with relative density to air >= 0.9;

 

- a toxic gas with a rat LC50 (4 hr) <= 2 mg/l (T-label according to EC rules);

 

- a liquid with a RIR >= 4000; or

 

- liquid with the ratio p20/LEL >= 10 (where p20 = saturated vapour pressure at 20°C in kPa and LEL = lower explosive limit in volume %).

 

- for gas or liquids with RIR > 100, or with flash point < 21°C,

 

- for extremely and highly flammable substances (in Fire hazard section).

 

- when phrase 'gas./air mixtures are explosive' or 'vapour/air mixtures are explosive' is used (in Explosion hazard section).

 

- for pyrophoric substances (according to EU criteria for R:17).

 

Both 21103 and 21101 can, if necessary, be completed with an indication of the circumstances under which these measures should be taken; for instance, ' in case of a large spill' can be indicated if appropriate.

21105000

Ventilation.

 

Expl. A spill often causes a harmful or even dangerous concentration of gases/vapours. Ventilation is a means of clearing the atmosphere. Moreover, for leaking gases it is the only method to remove them. In some situations however ventilation might increase the danger:

 

- substances in the form of powder may be dispersed by ventilation;

 

- local ventilation could cause faster evaporation of a liquid spill, thus increasing the vapour concentration if not enough fresh air is supplied; and

 

- concentrations above the upper explosion limit will decrease, thus bringing the atmosphere within the explosive limits.

 

Ind Ventilation should be applied judiciously and NEVER for solids which occur as a powder, and in general not for substances with a boiling point >= 350°C.

 

Use when phrase 13601 or phrase 13603 or phrase 13604040 (a harmful contamination of the air -will be reached very quickly- on evaporation of this substance at 20°C) is selected.

21107000

Collect leaking liquid in sealable []containers.

 

Expl. As a rule a leaking liquid should be collected in a 'sealable' container. However if the liquid could polymerize or decompose violently due to casual circumstances (e.g., contamination), the container should only be 'covered' rather than 'sealed' in order to allow any pressure which might tear the container to be released.

 

Ind. Apply to stable liquids with no risk of pressure-rise by polymerization, decomposition. All phrases with '[] containers' can be completed with a material specification. Use this possibility only when strictly necessary. Everyone knows for instance that acids should be collected in acid-resistant material, such an addition, therefore, being superfluous.

21211000

Wash away spilled liquid with plenty of water.

 

Expl. Substances which do not react violently with water and are not likely to cause serious environmental pollution, or result in an explosive atmosphere in the sewer can be washed away with plenty of water. Insoluble solids and liquids are not easily dispersed with water and may well block the drains.

 

Ind. Should only be used if the substance in question cannot cause serious environmental pollution or an explosive atmosphere in the sewer. Also see indication 21000. Should not be used if the substance reacts violently with water, or is insoluble in water.

21215000

Absorb remaining liquid in []sand or inert absorbent and remove to safe place.

 

Expl. This applies to liquids which must not be allowed to enter the sewer because they are highly flammable (i.e., flash point < 21°C) or are dangerous to health or may cause serious environmental pollution. 'Safe place' means a place that is free from explosion hazards and where no persons can be exposed to the substance or where no environmental pollution is possible. Substances spilled in the laboratory can be cleared away by special equipment obtainable from the suppliers of the chemicals.

 

Ind. This phrase may be completed by mentioning a special absorbent or by adding 'dry' if the substance should not come into contact with water. Also see indication 21000.

21217000

Do NOT wash away into sewer.

 

Expl. This is mentioned as an extra warning in case of very flammable liquids which are practically insoluble in water, thus causing a serious explosion hazard in the sewer. Also for insoluble strong smelling substances (mercaptanes, amines, etc.).

 

Ind. Applies for liquids with flash-point < 21°C and a solubility in water < 1 g/100 ml (i.e. not or only slightly soluble). Also see indication 21000. Do not use for environmental hazard - use 21245 instead.

21219000

Let solidify.

 

Expl. It is preferable to clean up solids rather than liquids. When no acute risks for people or environment and the freezing point is low enough, wait with cleaning till the spill is solidified.

 

Ind. Applies if a (warm) liquid with a melting or freezing point >25°C. (In warm climate zones: >35°C instead of  >25°C). Also see ind. 21000.

Ind. Applies if a gas, or a liquid or solid with a RIR >= 120, or powders with an OEL/TWA <= 0.1 mg/m3 and a RIR between 12 and 120. Applies also for freons.

21303000

Personal protection: P1 filter respirator for inert particles.

 

Expl. Equipment of this type is recommended as extra personal protection against substances that, when dispersed in air, will be harmful if inhaled. Dust masks or respirators for particles consist of a face piece and a filter, sometimes combined together. The mesh of the filter is selected according to the toxicity of the particles. Instead of describing the respirator being effective against inert, harmful, or toxic particles, it is often specified as respirator with a P1, P2, or P3 filter, respectively (P for particle). Respirators for particle filtration are only effective if the air contains a minimum of 18% oxygen and is free from harmful gases and vapours. They should only be used in situations where a high level of mobility of the wearer is required. The choice of the respirator's face piece also depends on the toxicity of the particles. Additional information can be given in ADDITIONAL INFORMATION.

 

Ind. Applies for substances with a b.p. >= 350°C, which may come as a fine powder or as mist (i.e., hazard of dispersion in air on handling). The dust respirator phrases should not be used if the substance is physiologically inert (i.e. 13619 is used) or if the spontaneous dispersion of the substance in air is highly unlikely for any reason, including its hygroscopic properties. Applies if the (estimated) OEL/TWA >= 10 mg/m3.

21305000

Personal protection: P2 filter respirator for harmful particles.

 

Expl. Equipment of this type is recommended as extra personal protection against substances that, when dispersed in air, will be harmful if inhaled. Dust masks or respirators for particles consist of a face piece and a filter, sometimes combined together. The mesh of the filter is selected according to the toxicity of the particles. Instead of describing the respirator being effective against inert, harmful, or toxic particles, it is often specified as respirator with a P1, P2, or P3 filter, respectively (P for particle). Respirators for particle filtration are only effective if the air contains a minimum of 18% oxygen and is free from harmful gases and vapours. They should only be used in situations where a high level of mobility of the wearer is required. The choice of the respirator's face piece also depends on the toxicity of the particles. Additional information can be given in ADDITIONAL INFORMATION.

 

Ind. Apply for substances with a b.p. >= 350°C, which may come as a fine powder or as a mist. (Hazard of dispersion in air on handling). The dust respirator phrases should not be used if the substance is physiologically inert or if the spontaneous dispersion of the substance in air is highly unlikely for any reason, including its hygroscopic properties. Applies if the (estimated) OEL/TWA < 10 mg/m3 and > 0.1 mg/m3.

21307000

Personal protection: P3 filter respirator for toxic particles.

 

Expl. Equipment of this type is recommended as extra personal protection against substances that, when dispersed in air, will be harmful if inhaled. Dust masks or respirators for particles consist of a face piece and a filter, sometimes combined together. The mesh of the filter is selected according to the toxicity of the particles. Instead of describing the respirator being effective against inert, harmful or toxic particles, it is often specified as respirator with a P1, P2 or P3 filter, respectively (P for particle). Respirators for particle filtration are only effective if the air contains a minimum of 18% oxygen and is free from harmful gases and vapours. They should only be used in situations where a high level of mobility of the wearer is required. The choice of the respirator's face piece also depends on the toxicity of the particles. Additional information can be given in ADDITIONAL INFORMATION.

 

Ind. Applies for substances with a b.p. >= 350°C, which may come as a fine powder or a mist (hazard of dispersion in air on handling). The dust respirator phrases should not be used if the substance is physiologically inert (i.e. 13619 is used) or if spontaneous dispersion of the substance in air is highly unlikely for any reason, including its hygroscopic properties. Applies if the (estimated) OEL/TWA <= 0.1 mg/m3 (and RIR < 12). Also for solid carcinogens and mutagens (see 13831, 13833, 13841, and 13843).

21309000

Personal protection: A/P2 filter respirator for organic vapour and harmful dust.

 

Expl. Applies to solid substances which may form aerosols of harmful dust and also generate noxious vapours.

 

Ind. Applies if an organic substance with an (estimated) OEL/TWA < 10 mg/m3 and a RIR index between 12 and 120.

21311000

Personal protection: complete protective clothing including self-contained breathing apparatus.

 

Expl. This is recommended for extra personal protection when the gas, vapour, or mist may cause injury both to the respiratory tract and the undamaged skin. The safety officer should be consulted for further details.

 

Ind. Applies to gases:

 

- if corrosive to the skin, or

 

- if absorbed by the skin

 

Applies to liquids and solids:

 

1) if the RIR > 120 and the vapour of the substance:

 

a) is corrosive to the skin, or

 

b) will be absorbed by the skin.  Or

 

2) if the substance on contact with (humid) air produces gases, vapours, or mists which

 

a) are corrosive to the skin, or

 

b) will be absorbed by the skin.

 

3) applies to compounds with RIR above 20 000 and which are absorbed through the skin.

 

Liquids and solids that can be absorbed by the skin should note regarded as also being absorbed in the gas or vapour phase. Absorption of gas/vapour is often much less serious than absorption of liquid/solid. Only when absorption of the substance in the gas or vapour phase is clearly mentioned in toxicological literature should this be used in the decision to apply 21311. Liquids whose vapours are absorbed by the skin to a high degree include, e.g., carbon disulphide, hydrogen cyanide, and methyl bromide (the latter is more a gas than a liquid).

 

N.B.: the application of 16207 'avoid all contact' does not automatically imply the use of 21311. 'Complete protective clothing including self-contained breathing apparatus' means practically a 'moonsuit' and should therefore only be applied in accordance with the criteria. Arguments should be provided for exceptions.

21313000

¦         STORAGE         ¦

 

Expl. The STORAGE instructions described in the ICSC are recommended primarily from the health and safety perspective. No consideration has been given, for example, to the (non-hazardous) deterioration of a chemical from the technical standpoint.

 

Ind. The Peer-Review Committee should decide whether a particular instruction is strictly necessary.

22101000

Fireproof.

 

Expl. This condition is specified for flammable substances and for flammable gases in cylinders. Also for solids which can develop combustible gases if in contact with water or water vapour and for solids which for any reason should be stored under fireproof conditions. 'Fire-proof' implies:

 

- the construction (degree of fire-resistance) and location (with respect to other buildings) of the storage accommodation in relation to the quantity and flammability of the stored substances;

 

- the possibility of collecting part of the stored liquid to limit spreading;

 

- compartments within a building to separate reactive substances from one another;

 

- special requirements for electrical, heating, and sewage installations;

 

- adequate ventilation to open air;

 

- provision of sufficient fire extinguishing agents and facilities;

 

- regulations, e.g., for filling, discharging, and handling (decanting preferably in a separate room);

 

- no-smoking and other warning signs; and

 

- suitable packaging of stored substances.

 

These items are often detailed in official national regulations; otherwise refer to specialized handbooks on fire prevention.

 

Ind. Applies to:

 

- gases in cylinders, only if combustible;

 

- substances with flash points < 61°C and all those for which 14101, 14103, 14105, 14115, or 14121 has been used; or

 

- substances which may decompose readily on heating, producing very toxic gases or vapours (rat LC50 (4 hr) <= 0.5 mg/l).

 

N.B.: The condition 'fire-proof' is intended to reduce the fire hazards caused by the storage of flammable substances to a practicable minimum. In other words, prevent the supply of flammable material to a fire that has started and prevent contact of flammables with sources of ignition. 'Fire-proof' is not generally intended to restrict the hazard of evaporation of a liquid with a toxic vapour; it would lead to storage of nearly all liquids under fireproof conditions. An exception could be made for substances which should be kept out of the heat of a fire because they readily decompose on heating, producing very toxic gases or vapours. The use of 'fire-proof' for this purpose should not be frequent. Also see 22301 ('cool').

22103000

Fireproof if in building.

 

Expl. 'Fire-proof' applies to gas-cylinders stored within a building, even if the gas is not combustible. See expl. 22000 and 22101.

Expl. This phrase is only used if a need for special packaging material cannot be regarded as common knowledge. It is assumed that persons who deal frequently with chemicals are acquainted with the corrosivity of acids, bases, and solutions in water to common steel and many other metals and with the unsuitability of many plastics for containing organic solvents or liquids. The supplier of the substance can usually advise the selection of an appropriate material.

23105000

Unbreakable packaging; put breakable packaging into closed unbreakable container.

 

Expl. This condition is specified for very dangerous substances. The breakable packaging is imparted greater protection by the unbreakable one. The enclosing vessel serves in addition as collecting vessel in case of rupture.

 

Ind. Apply if:

 

- a liquid with a RIR >= 4000;

 

- a liquid with a ratio of the p20 to LEL >= 300 (see 21103);

H226

EU Classification

 

Expl. In countries of European Union, chemicals have to be labelled with symbols of the most important hazards to man. The meanings of these symbols are related to the 'nature of the special risks attaching to dangerous substances' (R phrases), and to the 'safety advice concerning dangerous substances' (S phrases). Their precise meaning can be found in Annexes to EC Directive 93/21/EEC, as amended.

 

As the use of these symbols is fairly widespread, they will be understood when used on ICSCs in many countries. In addition to these symbols, the ICSCs should also contain Risk and Safety phrases, according to the criteria system devised by the European Union. In ICSCs, R and S phrases are only mentioned by their numbers. A 'Note' is sometimes attached and indicated by a letter: Note A, B,...

 

Ind. Complete with applicable numbers, separated by hyphens. The numbers of combined phrases are separated by slashes.

 

Example: R: 14-21/22-43.

 

Applies according to the official interpretation of the EC Directive.

 

Examine whether the selected ICSC Standard Phrases are compatible with the applicable R and S phrases for the substance in question. Check the draft of your ICSC for the differences and if correct, keep it that way. The deviations have to be discussed by the Peer-Review Committee.

Ind. Mention when available; see 11911 for the UN number. Complete with applicable numbers. These can be found in the United Nations Recommendations for Transport of Dangerous Goods prepared by the Committee of Experts on the Transport of Dangerous Goods, latest edition. See also the Legal File of the International Register of Potentially Toxic Chemicals (IRPTC) of United Nations Environment Programme, Geneva, latest edition. The recommendations on the packing of dangerous goods are based, in the main, on existing international and national regulations. Account is also taken of a prevailing trend to replace the detailed specifications of packaging, which may vary considerably from one country to another, by tests designed to ensure that packages containing dangerous goods can withstand normal conditions of transport and to ensure the desirable level of safety. When drafting the recommendations sight was not lost of improvements and changes that may occur as a result of progress in science and technology. So provisions are made for the use of packaging which, while not complying exactly with the specifications set out in the recommendations, would be nevertheless as satisfactory in every respect as those that do, and would successfully pass the recommended tests when prepared for transport.

 

Dangerous goods of all classes other than UN Hazard Classes 1, 2, 6.2, and 7 (see 23503) have for packing purposes been divided among three groups according to the degree of danger they present:

 

great danger:  Packing Group I;

 

medium danger: Packing Group II; and

 

minor danger:  Packing Group III.

24429000

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.

 

Expl. This applies to gases with little or no direct harmful action (so-called simple asphyxiants) and some liquids with a high vapour pressure. When these substances are dissipated in the work space the oxygen concentration in the air may drop below the limit required for breathing, especially in a confined workspace with poor ventilation. Special care is necessary when working with suffocating gases liquefied by cooling (so-called cryogenics). If accidentally released the liquid will evaporate quickly causing a very hazardous situation. When dealing with cryogenics, strict procedures have to be followed regarding instruction, supervision, ventilation, personal protection, monitoring, and rescue. Oxygen deficiency often leads to a sudden loss of consciousness without any preliminary symptoms. If this hazard is present, always work with a self-contained breathing apparatus; a filter respirator does not give any protection.

 

Ind. Applies if 13207 was used, or if the substance is a simple asphyxiant, as e.g.: acetylene, argon, ethane, ethylene, helium, hydrogen, methane, nitrogen, propane, propylene.

 

N.B.: Always check whether a gas is still considered to be a simple asphyxiant. The limit of a saturated vapour pressure > 100 mbar at 20°C (see 13207) has been chosen because the evaporation of a liquid with that vapour pressure can theoretically lower the oxygen content of the air in a closed space from a normal of 20.7 vol % to 18.6%, which is dangerously low.

 

24431

24431000

24438000

Uses of this substance as ultra-fine particles (<100nm) (nanoparticles) may produce adverse effects at concentrations well below those indicated on this Card. Utmost care should be taken.

 

Ind. This phrase should ONLY be used if ultrafine particles are generated during manufacture or use or the substance is specifically prepared and used in an ultrafine form AND there are specific references in the literature to biological effects of ultrafine particles on human and/or experimental animals for that substance. The inclusion of this statement should be a peer-review group decision

24501000

The odour warning when the exposure limit value is exceeded is insufficient.

 

Expl. Assessment of the quality of air based on the presence or absence of odours is not reliable and is discouraged. Odour threshold values are therefore not mentioned on the ICSCs. Odour may, nevertheless, provide a warning of the presence of a dangerous gas or vapour although this should not be depended on as an indication that an OEL has or has not been reached. One or another of these phrases can be used as an extra warning.

 

Ind. Use this phrase if the Odour Safety Factor < 26 and > 0. (Refer to Appendix 7).

24502000

There is no odour warning even when toxic concentrations are present.

 

Expl. Assessment of the quality of air based on the presence or absence of odours is not reliable and is discouraged. Odour threshold values are therefore not mentioned on the ICSCs. Odour may, nevertheless, provide a warning of the presence of a dangerous gas or vapour although this should not be depended on as an indication that a toxic concentration has or has not been reached. One or another of these phrases can be used as an extra warning.

 

Ind. Use this phrase if the substance is odourless and has a boiling point < 350°C.

24503000

The relation between odour and the occupational exposure limit cannot be indicated.

 

Expl. Assessment of the quality of air based on the presence or absence of odours is not reliable and is discouraged. Odour threshold values are therefore not mentioned on the ICSCs. Odour may, nevertheless, provide a warning of the presence of a dangerous gas or vapour although this should not be depended on as an indication that an OEL has or has not been reached. One or another of these phrases can be used as an extra warning.

 

Ind. Use this phrase if the boiling point < 350°C and the OEL/TWA or odour threshold value are not available. If Odour Safety Factor >= 26 or the substance has a boiling point >=350°C, none of these phrases should be used. (Substances with a b.p. >= 350°C are considered to not generate noxious vapours in harmful concentrations).

Expl. While this phrase could also be applicable to combustible substances, its inclusion means that the substance, though not combustible, may release phosgene at high temperatures or under influence of UV radiation. This applies in particular to certain non-combustible compounds containing chlorine.

 

Ind. Combine with 13333 for those substances which may develop phosgene or fluophosgene.

24513000

Check for peroxides prior to distillation; eliminate if found.

 

Expl. Treatment with ferrous sulfate or ferrous thiocyanate or by passing the liquid over a column of activated alumina are suitable methods to eliminate peroxides.

 

Ind. Combine with 13301/07.

24515000

NEVER pour water into this substance; when dissolving or diluting always add it slowly to the water.

 

Expl. This warning is used for substances which develop much heat on dissolving or diluting. The heat could cause sudden boiling or formation of corrosive mists.

 

Ind. Use e.g., for concentrated sulfuric acid or solid sodium hydroxide.

24517000

Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).

 

Ind. Applies if the cylinder contains a gas that is corrosive to steel.

Emergency Response

24711000

Transport Emergency Card: TEC (R)-[]

 

Expl. The CEFIC (Conseil Européen des Fédérations de l'Industrie Chimique) publishes a dangerous cargo card of this substance, which specifies the measures to be taken in the event of an accident during transport. Consult the head office of CEFIC at Brussels for further information.

 

Ind. Use this phrase if relevant and complete with the applicable number.

24801000

NFPA Code:  H[]; F[]; R[]; []

 

Expl. In this code the National Fire Protection Association (NFPA), Boston (USA) indicates:

 

-  the relative risk to health   H (blue)

 

-  the flammability                 F (red)

 

-  the instability or reactivity  R (yellow)

 

-  possible specific hazards      (white)

 

Each of the first three aspects is assigned a value from 0 to 4, the greater the risk, the higher the value assigned. Labelling with the so-called 'hazard diamond' is used frequently on fixed installations. The meaning of the numbers in hazard categories H, F, and R is summarized in National Fire Protection Association, NFPA Standard 704.

 

N.B.: The NFPA assessment of risks sometimes differs from that adopted by the Editorial Staff of the ICSCs. In addition, decomposition products arising from a fire are sometimes included among the health hazards. The fourth space of the diamond is used for special hazards. The NFPA specifies these special hazards as follows:

 

- Materials which demonstrate unusual reactivity with water shall be identified with the letter W with a horizontal line through the centre;

 

- Materials which possess oxidizing properties shall be identified by the letters OX; or

 

- Materials possessing radioactivity hazards shall be identified by the standard radioactivity symbol.

 

Ind. Use this symbol and complete it with the appropriate numbers. The numbers can be found in NFPA Standards 49 and 325, latest editions. If 'non-fire' and 'fire' numbers are given use the non-fire numbers. Do NOT use this phrase if the substance is not mentioned in the NFPA standards. The NFPA hazard ratings should be checked on  compatibility with the draft of the ICSC. If there are significant differences check for the correct application of the standard phrases used. When in doubt, keep to the phrases based on the indications of this guide and on your professional judgement.
