TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. NO open flames. NO contact with combustibles. Powder, alcohol-resistant foam, water spray, 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   Ventilation. Fresh air, rest.
Skin   Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes   Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion   Do not eat, drink, or smoke during work. Rinse mouth.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place. (Extra personal protection: P1 filter respirator for inert particles.)  

EMERGENCY RESPONSE STORAGE
  Separated from strong oxidants.
