|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, 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. Combat fire from a sheltered position.|
|Inhalation||Drowsiness. Unconciousness.||Use closed system or ventilation.||Fresh air, rest. 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||ON CONTACT WITH LIQUID: FROSTBITE.||Wear face shield.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.||

Check oxygen content before entering area.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Information except physical properties also apply for Isobutane (CAS 75-28-5).
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
