| TYPES OF HAZARD / EXPOSURE |
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.
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
|
|
| Inhalation |
Suffocation.
|
Ventilation.
|
Fresh air, rest. Artificial respiration may be needed. 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.
|
Face shield or eye protection in combination with breathing protection.
|
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 |
Evacuate danger area! Ventilation. Remove all ignition sources. Personal protection: complete protective clothing including self-contained breathing apparatus.

| IMPORTANT DATA |
PHYSICAL STATE; APPEARANCE:
ODOURLESS COLOURLESS COMPRESSED LIQUEFIED GAS
PHYSICAL DANGERS:
The gas is heavier than air, and may travel along the ground; distant ignition possible.
CHEMICAL DANGERS:
The substance may polymerize. Reacts violently with oxygen and oxidants causing fire and explosion hazard.
OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
|
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.
INHALATION RISK:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.
EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite.
|
| PHYSICAL PROPERTIES |
Boiling point: -6℃
Melting point: -185℃
Solubility in water: none
Vapour pressure, kPa at 21℃: 464
Relative vapour density (air = 1): 1.93
|
Flash point: Flammable Gas
Auto-ignition temperature: 385℃
Explosive limits, vol% in air: 1.6-10.0
|
| ENVIRONMENTAL DATA |
|
| NOTES |
Health effects of exposure to the substance have not been investigated. Check oxygen content before entering area. Card has been partly updated in October 2005. See section Emergency Response.
