TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Dry powder, carbon dioxide, foam.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION Dizziness. Headache. Nausea. Vomiting. Convulsions. Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Dizziness. Headache. Nausea. Vomiting. Convulsions. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention.
