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, water spray, foam, carbon dioxide.
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE   AVOID ALL CONTACT!  
Inhalation Cough. Laboured breathing. Sore throat. Ventilation. Fresh air, rest. Half-upright position. Refer for medical attention.
Skin Redness. Pain. Protective gloves. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. 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. (Further see Inhalation). Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
