ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Extremely flammable. Many reactions may cause fire or explosion. Gas/air mixtures are explosive. | NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. Do not handle cylinders with oily hands. | Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. |
Use appropriate engineering controls. | |||
