ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames. NO contact with oxidants.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Above 79°C explosive vapour/air mixtures may be formed.
Above 79°C use a closed system, ventilation.

EXPOSURE
PREVENT GENERATION OF MISTS!

 •INHALATION Blue lips or finger nails. Blue skin. Convulsions. Dizziness. Laboured breathing. Vomiting. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. MAY BE ABSORBED! (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES Redness. Pain.
Face shield or 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 (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give plenty of water to drink. Give a slurry of activated charcoal in water to drink. Refer for medical attention. See Notes.
