|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames, NO sparks and NO smoking.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide.|
|EXPLOSION||Gas/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.||In case of fire: keep cylinder cool by spraying with water.|
|Inhalation||Dizziness. Lethargy. Headache. Abdominal cramps.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves. Protective clothing.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain. Blurred vision.||Wear face shield or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Do not eat, drink, or smoke during work.|
|PACKAGING & LABELLING|
