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, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Suffocation. See Notes.  Use 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 See Skin.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

IMPORTANT DATA
Physical State; Appearance
ODOURLESS COLOURLESS COMPRESSED LIQUEFIED GAS. 

Physical dangers
The gas is heavier than air and may accumulate in lowered spaces causing a 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 substance 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 ENVIRONMENTAL DATA
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 (estimated) 
 

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
