TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.   Water spray, alcohol-resistant foam, powder, carbon dioxide.
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE   PREVENT DISPERSION OF DUST!  
Inhalation Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest.
Skin   Protective gloves. Rinse and then wash skin with water and soap.
Eyes Redness. Safety spectacles Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion Sore throat. Abdominal pain. Do not eat, drink, or smoke during work. Rinse mouth.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place.  

EMERGENCY RESPONSE SAFE STORAGE
  Dry. Well closed. Separated from chlorine.
