  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable.  Gas/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  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.  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.  In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Drowsiness. Unconsciousness.  Use closed system or 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.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

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. The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system. 

Inhalation risk
On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas. 

Effects of long-term or repeated exposure
 


Occupational exposure limits
MAK: 1800 mg/m3, 1000 ppm; peak limitation category: II(4); pregnancy risk group: D 

ENVIRONMENT
 

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.
