TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Water spray, powder, carbon dioxide.
EXPLOSION Above 26°C explosive vapour/air mixtures may be formed.
Above 26°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION Cough.
Avoid inhalation of dust.
Fresh air, rest.
•SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
•EYES Redness. Pain.
Safety goggles
Rinse with plenty of water (remove contact lenses if easily possible).
•INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink.
