TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, 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


 •INHALATION
Ventilation.
Fresh air, rest.
 •SKIN Redness. Pain.
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.
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.
Rinse mouth.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Then wash away with plenty of water.
Keep in the dark. Separated from strong oxidants.
