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 Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough.
Avoid inhalation of dust.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES Redness.
Safety goggles
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION Flushing of the face.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Store in an area without drain or sewer access. Separated from strong acids, bases and oxidants .

Signal: Warning
Causes eye irritation
Harmful to aquatic life
