|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 water spray, alcohol-resistant foam, dry powder, carbon dioxide.|
|EXPLOSION||Gas/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.||In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|Inhalation||Burning sensation. Cough. Headache. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed. See Notes.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. 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. Refer for medical attention .|
|Eyes||Redness. Pain. Blurred vision.||Wear safety goggles 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|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid. Remove gas with fine water spray. Do NOT let this chemical enter the environment.||

Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).
