TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible under specific conditions. Heating will cause rise in pressure with risk of bursting. See Notes.	NO open flames. NO contact with hot surfaces.	Powder, water spray, foam, carbon dioxide.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS!
Inhalation	Cough. Dizziness. Drowsiness. Headache. Nausea.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	MAY BE ABSORBED! Dry skin. Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes	Redness.	Safety spectacles or face shield.	Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
Ingestion	Aspiration hazard! ( See Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention. Do NOT induce vomiting.

1,1,2-TRICHLOROETHANE

ICSC: 0080

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases including hydrogen chloride, and phosgene. Reacts with strong bases, strong oxidants and metals causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009).
MAK: 10 ppm, 55 mg/m³ Peak limitation category: II(2); skin absorption (H); Carcinogen category: 3B; (DFG 2008).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C .

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system , resulting in lowering of consciousness, and kidneys and liver resulting in impaired functions. If swallowed the substance may cause vomiting, and could result in aspiration pneumonitis.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. Repeated contact with skin may cause dryness and cracking.

PHYSICAL PROPERTIES

Boiling point: 114°C
Melting point: -36°C
Relative density (water = 1): 1.4
Solubility in water, g/100 ml at 20°C: 0.45 (very poor)
Vapour pressure, kPa at 20°C: 2.5
Relative vapour density (air = 1): 4.6

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.09
Explosive limits, vol% in air: 6-15.5
Octanol/water partition coefficient as log Pow: 2.35
Viscosity, mm²/s at 25 °C: 1.17

ENVIRONMENTAL DATA

The substance is harmful to aquatic organisms.

NOTES

Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions. Use of alcoholic beverages enhances the harmful effect. The relation between odour and the occupational exposure limit cannot be indicated. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
