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