|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gas/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, foam, carbon dioxide. In case of fire: keep cylinder cool by spraying with water.|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Dizziness. Drowsiness. Headache.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.|
|Eyes||ON CONTACT WITH LIQUID: FROSTBITE.||Wear safety goggles or eye protection in combination with breathing protection.||Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Remove all ignition sources. Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Shut off cylinder if possible. Isolate the area until the gas has dispersed. Remove gas with fine water spray.||
