TRICHLOROFLUOROMETHANE

ICSC: 0047

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS GAS OR HIGHLY VOLATILE LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers The gas is heavier than air. The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases of hydrogen chloride (see ICSC 0163), phosgene (see ICSC 0007), hydrogen fluoride (see ICSC 0283) and carbonyl fluoride (see ICSC 0633). Reacts with powdered aluminium, powdered zinc, magnesium shavings, lithium shavings and granular barium.	Formula: CCl₃F Molecular mass: 137.4 Boiling point: 24°C Melting point: -111°C Relative density (water = 1): 1.49 Solubility in water, g/100ml at 20°C: 0.1 Vapour pressure, kPa at 20°C: 89.0 Relative vapour density (air = 1): 4.7 Relative density of the vapour/air-mixture at 20°C (air = 1): 4.4 Octanol/water partition coefficient as log Pow: 2.53

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure The liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system. This may result in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness. See Notes.	Inhalation risk On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system. This may result in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness. See Notes.

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

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 1000 ppm as STEL; A4 (not classifiable as a human carcinogen). MAK: 5700 mg/m³, 1000 ppm; peak limitation category: II(2); pregnancy risk group: C

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. The occupational exposure limit value should not be exceeded during any part of the working exposure. The odour warning when the exposure limit value is exceeded is insufficient. 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.
