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 STORAGE PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Fireproof if in building. Cooled.
Special insulated cylinder.

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.

CHEMICAL DANGERS:

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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
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

N O T E S
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area.
