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	Containers may burst in the heat of a fire!		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. Unconsciousness.	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.	Safety goggles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid.	UN classification UN Hazard Class: 2.2 GHS classification Signal: Warning Cylinder May be harmful if inhaled Contains refrigerated gas; may cause cryogenic burns or injury

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-20S1013 or 20G2A	Fireproof if in building. Cool. Ventilation along the floor.

IMPORTANT DATA

Physical State; Appearance
ODOURLESS, COLOURLESS COMPRESSED LIQUEFIED GAS.

Physical dangers
The gas is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen. Build up of static electricity can occur at fast flow rates and may ignite any explosive mixtures present. Free-flowing liquid condenses to form extremely cold dry ice.

Chemical dangers
The substance decomposes on heating above 2000°C producing 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 liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas.

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

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/100 ml 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.
