TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances.  NO open flames, NO sparks and NO smoking. NO contact with flammables. NO contact with reducing agents.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with combustible substances or reducing agents.    In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Cough. Dizziness. Sore throat. See Notes.    Fresh air, rest. 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 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. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid.  Special insulated container.

Fireproof. Separated from combustible substances and reducing agents. Cool. 

IMPORTANT DATA
Physical State; Appearance
LIQUEFIED GAS. COLOURLESS-TO-BLUE EXTREMELY COLD LIQUID. 

Physical dangers
The gas is heavier than air. 

Chemical dangers
The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
 

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. The substance at very high concentrations is irritating to the respiratory tract. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA

NOTES
Work clothes saturated with oxygen may be a serious fire hazard.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Inhalation symptoms are characteristic of exposure to extremely high concentrations only.
Also consult ICSC #0138 Oxygen.
Card has been partly updated in October 2005.
