|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames.||In case of fire in the surroundings, use appropriate extinguishing media.|
|EXPLOSION||In case of fire: keep cylinder cool by spraying with water.|
|Inhalation||Irregular heartbeat. Confusion. Drowsiness. Unconciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.|
|Skin||ON CONTACT WITH LIQUID: FROSTBITE.||Cold-insulating gloves.||ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear safety goggles.||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.|

|This substance may be hazardous to the environment. Special attention should be given to its impact on the ozone layer.|
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Freon 22, Frigen 22, Halon 22 are trade names.
Card has been partially updated in July 2007: see Occupational Exposure Limits.
