TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking. NO contact with strong oxidants.
powder, alcohol-resistant foam, water spray, carbon dioxide,
EXPLOSION Above 44°C explosive vapour/air mixtures may be formed.
Above 44°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE


•INHALATION
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Safety goggles,
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Cough. Nausea. Sore throat.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting.
