TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible. Heating will cause rise in pressure with risk of bursting.
|
|
In case of fire in the surroundings: all extinguishing agents allowed.
|
| EXPLOSION |
|
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

| EXPOSURE |
|
|
|
| Inhalation |
Suffocation (see Notes).
|
Ventilation.
|
Fresh air, rest. Artificial respiration if indicated. 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 |
See Skin.
|
Safety goggles, or face shield.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
|
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Ventilation. NEVER direct water jet on liquid (extra personal protection: chemical protection suit including self-contained breathing apparatus).
|
UN Hazard Class: 2.2
Special insulated cylinder. |
| EMERGENCY RESPONSE | STORAGE |
Transport Emergency Card: TEC (R)-20G48
|
Fireproof if in building. Cooled.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
ODOURLESS , COLOURLESS, COMPRESSED LIQUEFIED GAS PHYSICAL DANGERS: The gas is heavier than air. and may accumulate in low ceiling spaces causing deficiency of oxygen. OCCUPATIONAL EXPOSURE LIMITS: TLV 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: The liquid may cause frostbite. |
| PHYSICAL PROPERTIES | |
|
Boiling point: -153°C
Melting point: -157°C Solubility in water: none Relative vapour density (air = 1): 2.9 |
Octanol/water partition coefficient as log Pow: 1.2 (est.)
|
| ENVIRONMENTAL DATA | |
|
|
| NOTES | |
|
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
