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. 
 
EXPOSURE      
Inhalation Unconciousness. Weakness. Suffocation. See Notes.  Use ventilation.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.

ODOURLESS COLOURLESS COMPRESSED GAS. 

Physical dangers
 

Chemical dangers
 

Occupational exposure limits
TLV (SIMPLE-ASPHYXIANT): (ACGIH 2004). 

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. See Notes. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: -196°C
Melting point: -210°C
Solubility in water: poor
Relative vapour density (air = 1): 0.97  
 

NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Card has been partly updated in April 2005. See sections Emergency Response, Occupational Exposure Limits.
