IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

Chemical dangers
The substance decomposes on heating producing phosgene, hydrogen fluoride and hydrogen chloride.

Occupational exposure limits
TLV not established.

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

Inhalation risk
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance irritates the eyes. The substance may cause effects on the central nervous system and cardiovascular system, resulting in narcosis and cardiac disorders.

Effects of long-term or repeated exposure
The substance may have effects on the liver.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 28°C Melting point: -107°C Relative density (water = 1): 1.5 Solubility in water, g/100 ml at 25°C: 0.21 Vapour pressure, Pa at 25°C: 14 Relative vapour density (air = 1): 6.4	This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer. It is strongly advised not to let the chemical enter into the environment because it persists in the environment. Avoid release to the environment in circumstances different to normal use.

NOTES

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
