  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion. Explosive.  NO open flames, NO sparks and NO smoking.  Do NOT expose to friction or shock. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  In case of fire in the surroundings, use appropriate extinguishing media.  Combat fire from a sheltered position. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Headache.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety goggles or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Dizziness. Headache.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .
