PHYSICAL & CHEMICAL INFORMATION
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.	Formula: CO₂ Molecular mass: 44.0 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

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. Inhalation of high levels may cause unconsciousness. Asphyxiation.	Inhalation risk On loss of containment this substance can cause serious risk of suffocation when in confined areas. Effects of long-term or repeated exposure The substance may have effects on the metabolism.

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. Inhalation of high levels may cause unconsciousness. Asphyxiation.

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

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

OCCUPATIONAL EXPOSURE LIMITS
TLV: 5000 ppm as TWA; 30000 ppm as STEL. MAK: 9100 mg/m³, 5000 ppm; peak limitation category: II(2). EU-OEL: 9000 mg/m³, 5000 ppm as TWA

ENVIRONMENT

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. There is no odour warning even when toxic concentrations are present. Other UN classification numbers for transport are: UN 1845 carbon dioxide, solid (Dry ice); UN 2187 carbon dioxide refrigerated liquid.
