TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Burning sensation. Sore throat. Cough. Laboured breathing. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain. Severe deep burns.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .
