TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Explosive. 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.
Do NOT expose to friction or shock. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
Combat fire from a sheltered position.
EXPOSURE


Inhalation Dizziness. Headache.
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.
