	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. Above 46°C explosive vapour/air mixtures may be formed.	NO open flames, NO sparks and NO smoking. NO contact with hot surfaces. Above 46°C use a closed system, ventilation and explosion-proof electrical equipment.	Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
