|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.||Use carbon dioxide, powder, water spray.|
|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). Use non-sparking handtools.||In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.|
|Inhalation||Dizziness. Drowsiness. Unconciousness. Suffocation.||Use ventilation.||Fresh air, rest.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||See Skin.||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|
|Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Remove vapour with fine water spray. NEVER direct water jet on liquid.||
