	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. Heating will cause rise in pressure with risk of bursting.	NO contact with hot surfaces. See Chemical Dangers.	In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Confusion. Dizziness. Headache. Unconsciousness.	Use ventilation, local exhaust or breathing protection.	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.
Eyes	See Skin.	Wear safety goggles, 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 refer for medical attention.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUEFIED 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 burning. Decomposes on contact with hot surfaces. This produces toxic and corrosive fumes including hydrogen chloride, hydrogen fluoride and phosgene. Incompatible with certain metal powders (aluminium, zinc, beryllium), certain alloys (zinc, magnesium), certain plastics and natural rubber.	Formula: CClF₃ Molecular mass: 104.5 Boiling point: -81.4°C Melting point: -181°C Relative density (water = 1): 1.3 Solubility in water: none Relative vapour density (air = 1): 3.6 Octanol/water partition coefficient as log Pow: 1.65

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
Exposure could cause narcotic effects. Exposure at high concentrations could cause asphyxiation. The substance may cause effects on the cardiovascular system. This may result in impaired functions.

Inhalation risk
On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas. See Notes.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS
MAK: 4300 mg/m³, 1000 ppm; peak limitation category: II(8); pregnancy risk group: D

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. Physician should give special attention to the drugs used in treatment because of the effects of the substance on cardiac rhythm. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
