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.
•EYES Redness.
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 take to a doctor.
•INGESTION Dizziness. Headache.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
