  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.    NO contact with hot surfaces.    Use water spray, foam, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Drowsiness. Confusion. Unconsciousness.  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. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: self-contained breathing apparatus. Do NOT let this chemical enter the environment. Ventilation. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Carefully collect remainder. Then store and dispose of according to local regulations.

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 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. This substance may be hazardous to the environment. Special attention should be given to 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 the area.
