HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.     
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE      
Inhalation   Use local exhaust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap.
