TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Liquid formulations containing organic solvents may be flammable.
NO open flames.
Powder . Foam. Carbon dioxide.
EXPLOSION

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 and then wash skin with water and soap.
•EYES
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. Wash hands before eating.
Rinse mouth.
