TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Water spray. Alcohol-resistant foam. Powder. Carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


•INHALATION Headache. Nausea. Giddiness. Palpitations.
Closed system and ventilation.
Fresh air, rest.
•SKIN
Protective gloves.
Rinse and then wash skin with water and soap.
•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. Rest.

PACKAGING & LABELLING

Personal protection: filter respirator for organic gases and vapours. Do NOT wash away into sewer. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Fireproof. Separated from strong oxidants. Cool. Store in an area without drain or sewer access.
