	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 63°C explosive vapour/air mixtures may be formed.	NO open flames. Above 63°C use a closed system, ventilation and explosion-proof electrical equipment.	Use water spray, foam, powder, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use ventilation.	Fresh air, rest.
Skin	Redness. Pain.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Then wash away with plenty of water.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Keep in the dark. Separated from strong oxidants.
