ACUTE HAZARDS | PREVENTION | FIRE FIGHTING | |
---|---|---|---|
FIRE & EXPLOSION | Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire. Cylinder may explode in heat of fire. Gas/air mixtures are explosive. Risk of fire and explosion on contact with strong oxidizing agents. | NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents or mercury. Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. | Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. |

SYMPTOMS | PREVENTION | FIRST AID | |
Inhalation | Sore throat. Cough. Burning sensation in the throat and chest. Shortness of breath. | Use ventilation, local exhaust or breathing protection. | Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. |
Skin | ON CONTACT WITH LIQUID: FROSTBITE. Redness. Pain. | Cold-insulating gloves. Protective clothing. | Wear protective gloves when administering first aid. ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer immediately for medical attention. |
Eyes | Redness. Pain. Blurred vision. Severe burns. ON CONTACT WITH GAS: FROSTBITE. | Wear face shield or eye protection in combination with breathing protection. | Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. |
