TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 84°C explosive vapour/air mixtures may be formed.

EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION Burning sensation. Sore throat. Cough. Dizziness. Headache. Nausea. Shortness of breath.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
 •EYES Redness. Pain. Blurred vision.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Abdominal pain. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting.
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. Personal protection: filter respirator for organic gases and vapours.
Separated from strong oxidants, strong bases, amines .
