ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Highly flammable. Vapour/air mixtures are explosive. Heating will cause rise in pressure with risk of bursting. | NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. | Use water spray, foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. |
