  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Heating will cause rise in pressure with risk of bursting.        In case of fire in the surroundings, use appropriate extinguishing media.   

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Lethargy. Headache. Suffocation.  Use 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 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. 
Ingestion

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
Asphyxiation. The liquid may cause frostbite. 

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
 

ENVIRONMENT
 

NOTES
Other UN number: 1006 Argon, compressed.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
