TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION
EXPOSURE
•INHALATION Ventilation. Fresh air, rest.
•SKIN Protective gloves. Rinse and then wash skin with water and soap.
•EYES Safety spectacles . First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Nausea. Vomiting. Abdominal pain. Diarrhea. Do not eat, drink, or smoke during work. Give plenty of water to drink.
