|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable.||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, alcohol-resistant foam, water spray, carbon dioxide.|
|EXPLOSION||Gas/air mixtures are explosive. Risk of fire and explosion as a result of decomposition when heated.||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.|
|EXPOSURE||STRICT HYGIENE! AVOID ALL CONTACT!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Cough. Drowsiness. Headache. Nausea. Sore throat. Vomiting. Weakness.||Use closed system or ventilation.||Fresh air, rest. Refer for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE. Dry skin. Redness. Pain.||Protective gloves. Cold-insulating gloves. Protective clothing.||Remove contaminated clothes. 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 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. Wash hands before eating.|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. Do NOT wash away into sewer. NEVER direct water jet on liquid. Remove gas with fine water spray.||

|The substance is harmful to aquatic organisms.|
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
The odour warning when the exposure limit value is exceeded is insufficient.
Card has been partly updated in April 2005.
