	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	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, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Drowsiness. Unconsciousness.	Use ventilation.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
Eyes	ON CONTACT WITH LIQUID: FROSTBITE.	Wear face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Ventilation. Do NOT let this chemical enter the environment.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 2.2

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance LIQUEFIED COMPRESSED GAS WITH CHARACTERISTIC ODOUR. Physical dangers The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers Decomposes on contact with open flames or very hot surfaces. This produces toxic gases including phosgene, hydrogen fluoride, hydrogen chloride and hydrogen bromide.	Formula: CBrClF₂ Molecular mass: 165.4 Boiling point: -4°C Melting point: -160.5°C Solubility in water: none Relative vapour density (air = 1): 5.7 Octanol/water partition coefficient as log Pow: 2.1

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system. This may result in cardiac disorders.

Inhalation risk
On loss of containment this substance can cause serious risk of suffocation when in confined areas.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
Avoid release to the environment because of its impact on the ozone layer.

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
