TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with hot surfaces.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Drowsiness. Confusion. Unconciousness.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion     Do NOT induce vomiting.

IMPORTANT DATA
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. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

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

Inhalation risk
On loss of containment this substance can cause serious risk of suffocation when in confined areas. 

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. 

Effects of long-term or repeated exposure
