TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE 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 water spray, alcohol-resistant foam, dry 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).
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE


Inhalation Dizziness. Nausea.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
Skin ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.
Eyes
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Remove vapour with fine water spray. Personal protection: self-contained breathing apparatus.
