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.
Powder, alcohol-resistant foam, water spray, 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. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest.
 •SKIN Redness.
Protective gloves.
Rinse and then wash skin with water and soap.
 •EYES Redness.
Safety goggles
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION Sore throat.
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: P2 filter respirator for harmful particles. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting, then remove to safe place. Do NOT let this chemical enter the environment.
Provision to contain effluent from fire extinguishing. Separated from strong acids, oxidants . Store in an area without drain or sewer access.
