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 contact with hot surfaces or flames. This produces hydrogen chloride, hydrogen fluoride and phosgene. Reacts with strong acids.

EXPOSURE & HEALTH EFFECTS

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

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

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
The substance is harmful to aquatic organisms. 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.
