TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 40°C explosive vapour/air mixtures may be formed.
Above 40°C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
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.
Safety spectacles.
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.
