| 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. 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.
|
| EXPOSURE |
|
|
|
| Inhalation |
Drowsiness. Unconsciousness.
|
Closed system and 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.
|
Face shield.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

| 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, and may accumulate in low ceiling spaces causing deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated.
OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Aliphatic hydrocarbon gases) 1000 ppm as TWA; (ACGIH 2005).
MAK: 1000 ppm, 1800 mg/m3; Peak limitation category: II(4); Pregnancy risk group: D; (DFG 2006).
|
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.
INHALATION RISK:
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.
EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system.

| ENVIRONMENTAL DATA |
|
| NOTES |
Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Card has been partially updated in July 2007: see Occupational Exposure Limits.
