  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air.    Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.  Use water spray, foam, powder, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
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. Wash away remainder with plenty of water. 

According to UN GHS Criteria
