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.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Above 63C explosive vapour/air mixtures may be formed.
Above 63C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE


Inhalation
Ventilation.
Fresh air, rest.
Skin Redness. Pain.
Protective gloves.
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
Do not eat, drink, or smoke during work.
Rinse mouth.
SPILLAGE DISPOSAL PACKAGING & LABELLING
