TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion as a result of decomposition when heated.    In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position. 
 
EXPOSURE      
Inhalation Dizziness. Headache. Elevated blood pressure. Increased heart rate. Suffocation. Unconciousness.  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.

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. Free-flowing liquid condenses to form extremely cold dry ice. 

Chemical dangers
Decomposes above 2000°C . This produces toxic carbon monoxide. 

Occupational exposure limits
TLV: 5000 ppm as TWA; 30000 ppm as STEL; (ACGIH 2006).
MAK: 5000 ppm, 9100 mg/m³; Peak limitation category: II(2); (DFG 2006). 

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

Inhalation risk
On loss of containment this substance can cause serious risk of suffocation when in confined areas. 

Effects of short-term exposure
Rapid evaporation of the liquid may cause frostbite. Inhalation of high levels may cause unconsciousness. Asphyxiation. 

Effects of long-term or repeated exposure
The substance may have effects on the metabolism. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: -79°C
Solubility in water, ml/100ml at 20°C: 88
Vapour pressure, kPa at 20°C: 5720
Relative vapour density (air = 1): 1.5
Octanol/water partition coefficient as log Pow: 0.83  
 

NOTES
Carbon dioxide is given off by many fermentation processes (wine, beer, etc.) and is a major component of flue gas.
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
No odour warning if toxic concentrations are present.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Other UN classification numbers for transport are: UN 1845 carbon dioxide, solid (Dry ice); UN 2187 carbon dioxide refrigerated liquid.
