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.  Use powder, alcohol-resistant foam, water spray, carbon dioxide. 
EXPLOSION Heating will cause rise in pressure with risk of bursting.    In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.  PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Convulsions.  Avoid inhalation of dust. Use local exhaust or breathing protection.  Fresh air, rest. Refer immediately for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Convulsions.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give one or two glasses of water to drink. Refer immediately for medical attention. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
