  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.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

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

According to UN GHS Criteria

 

Transportation
UN Classification
 

STORAGE
