TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with water, acid(s) or halogens. NO open flames, NO sparks, and NO smoking. Special powder, dry sand, NO other agents.
EXPLOSION Risk of fire and explosion. on contact with acid(s), halogens, water.   Combat fire from a sheltered position.
 
EXPOSURE      
Inhalation Cough. Sore throat. Burning sensation. Closed system and ventilation. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin Pain. Blisters. Serious skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Severe deep burns. loss of vision. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Burning sensation. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention.
