| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.
|
|
In case of fire in the surroundings: all extinguishing agents allowed.
|
| EXPLOSION |
|
|
In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
|
| Inhalation |
Sore throat. Drowsiness. Confusion. Nausea. Vomiting. Cough. Unconsciousness. Symptoms may be delayed (see Notes).
|
Local exhaust or breathing protection.
|
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
|
| Skin |
ON CONTACT WITH LIQUID: FROSTBITE. THE LIQUID MAY BE ABSORBED. Redness. Pain.
|
Cold-insulating gloves. Protective clothing.
|
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
|
| Eyes |
ON CONTACT WITH LIQUID: FROSTBITE. Redness. Pain.
|
Face shield, or eye protection in combination with breathing protection.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
Do not eat, drink, or smoke during work.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS, WITH PUNGENT ODOUR. PHYSICAL DANGERS: The gas is heavier than air. CHEMICAL DANGERS: The substance decomposes on heating producing toxic and corrosive fumes (hydrogen cyanide, hydrochloric acid, nitrogen oxides). Reacts slowly with water or water vapour to form hydrogen chloride. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.3 ppm; as (ceiling value) (ACGIH 1999). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. EFFECTS OF SHORT-TERM EXPOSURE: Tear drawing. The substance severely irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the cellular respiration, resulting in convulsions and unconsciousness. Exposure may result in death. Medical observation is indicated. See Notes. Inhalation of the substance may cause lung oedema (see Notes). The effects may be delayed. Rapid evaporation of the liquid may cause frostbite. Medical observation is indicated. | ||
| PHYSICAL PROPERTIES | |||
|
Boiling point: 13.8°C Melting point: -6°C Solubility in water: soluble Vapour pressure, kPa at 21.1°C: 1987 Relative vapour density (air = 1): 2.16 |
|||
| ENVIRONMENTAL DATA | |||
|
The substance is very toxic to aquatic organisms.
| |||
| NOTES | |||
|
The occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder). Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
