TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, foam, powder, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.   
 
EXPOSURE      
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin     Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.
