| TYPES OF HAZARD / EXPOSURE | 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.
|
| EXPOSURE |
|
|
|
| Inhalation |
Cardiac arrhythmia. Confusion. Drowsiness. Unconsciousness. |
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.
|
Safety goggles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
Do not eat, drink, or smoke during work.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED LIQUEFIED GAS PHYSICAL DANGERS: The gas is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen. CHEMICAL DANGERS: On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases including hydrogen chloride (see ICSC0163), phosgene (See ICSC 0007), hydrogen fluoride (See ICSC 0283), carbonyl fluoride (See ICSC 0633). Attacks magnesium and its alloys. OCCUPATIONAL EXPOSURE LIMITS: TLV: 1000 ppm as TWA A4 (ACGIH 2001). MAK: 500 ppm, 1800 mg/m³ Peak limitation category: II(8) Pregnancy risk group: C (DFG 2006). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation. INHALATION RISK: On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas. EFFECTS OF SHORT-TERM EXPOSURE: Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system, resulting in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness. See Notes. | ||

| ENVIRONMENTAL DATA | |||
|
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
| |||
| NOTES | |||
|
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.
