TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Fine water spray, Carbon dioxide.
EXPLOSION Above 27C explosive vapour/air mixtures may be formed.
Above 27C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

 •INHALATION Cough. Sore throat. 4 (occupational exposure) data are too weak
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain. skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.
 •EYES Redness. Pain.
Face shield or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
 •INGESTION Cough. Burning sensation in the throat and chest.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. cute oral toxicity, 24 (LD50 oral rat male=300mg/kg bw; LD50 oral rat female=414mg/kg bw)
