TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Foam. Carbon dioxide. Dry powder. Water in large amounts.
EXPLOSION Above 50C explosive vapour/air mixtures may be formed.
Above 50C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION Sore throat. Cough.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Seek medical attention if you feel unwell
 •SKIN Redness. Pain.
Protective gloves. Protective clothing.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention.
 •EYES Redness. Pain.
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 Sore throat.
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
