PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

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

Chemical dangers
Decomposes on heating. This produces phosgene, hydrogen fluoride and hydrogen chloride. 

Formula: C2HCl2F3 / CHCl2CF3
Molecular mass: 152.9
Boiling point: 28°C
Melting point: -107°C
Relative density (water = 1): 1.5
Solubility in water, g/100ml at 25°C: 0.21
Vapour pressure, Pa at 25°C: 14
Relative vapour density (air = 1): 6.4  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes. The substance may cause effects on the central nervous system and cardiovascular system. This may result in narcosis and cardiac disorders. 

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

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


OCCUPATIONAL EXPOSURE LIMITS
MAK: carcinogen category: 3 

ENVIRONMENT
Avoid release to the environment because of its impact on the ozone layer. It is strongly advised not to let the chemical enter into the environment because it is persistent. 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.
