  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.  Use water spray, foam, powder, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
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 CLASSIFICATION & 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.
