TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 46C explosive vapour/air mixtures may be formed.
Above 46C use a closed system, ventilation, and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding).
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


Inhalation
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
Skin Dry skin.
Protective gloves.
Rinse skin with plenty of water or shower.
Eyes
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. Do NOT induce vomiting.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Remove all ignition sources. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: P2 filter respirator for harmful particles.)
