  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Heating will cause rise in pressure with risk of bursting.  NO open flames.    Use powder, alcohol-resistant foam, water spray, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE. PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Convulsions.  Avoid inhalation of dust. Use local exhaust or breathing protection.  Fresh air, rest. Refer immediately for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap.
