| UN #: 1010 (stabilized)
|EC Number: 203-450-8
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Extremely flammable. Gas/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state.||Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with water spray, powder, carbon dioxide, foam. In case of fire: keep cylinder cool by spraying with water.|
|AVOID ALL CONTACT!|
|Inhalation||Cough. Headache. Drowsiness.||Use closed system and ventilation.||Fresh air, rest. Refer for medical attention.|
|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||ON CONTACT WITH LIQUID: FROSTBITE.||Wear face shield.||ON FROSTBITE: rinse with plenty of water. Refer immediately for medical attention.|
|Ingestion||Do not eat, drink, or smoke during work.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Shut off cylinder if possible. Isolate the area until the gas has dispersed. NEVER direct water jet on liquid.||
