TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 74C explosive vapour/air mixtures may be formed.
Above 74C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Burning sensation. Cough. Headache. Nausea. Shortness of breath. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
 •SKIN Skin burns. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness. Pain. Severe deep burns.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Burning sensation. Sore throat. (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).
Separated from food and feedstuffs . Cooled. Well closed. Ventilation along the floor.
Do not transport with food and feedstuffs.
