ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 63°C explosive vapour/air mixtures may be formed.
Above 63°C use a closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE
AVOID ALL CONTACT!

•INHALATION Cough. Sore throat. Dullness. Nausea.
Closed system.
Fresh air, rest. Refer for medical attention.
•SKIN Redness. Pain.
