  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  Rinse with plenty of water for several minutes (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
