TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
|
|
In case of fire in the surroundings: all extinguishing agents allowed.
|
| EXPLOSION |
|
|
In case of fire: keep cylinder cool by spraying with water.

| EXPOSURE |
|
|
|
| Inhalation |
Confusion. Drowsiness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Artificial respiration if indicated. 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 |
|
Safety goggles.
|
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 |
Ventilation. NEVER direct water jet on liquid (extra personal protection: self-contained breathing apparatus).
|
UN Hazard Class: 2.2
Special insulated cylinder. |
| EMERGENCY RESPONSE | STORAGE |
Transport Emergency Card: TEC (R)-644
|
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. CHEMICAL DANGERS: On contact with hot surfaces or flames this substance decomposes forming corrosive and very toxic fumes (hydrogen fluoride, ICSC # 0283). OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
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: Inhalation of the vapour may cause depression of the central nervous system. The liquid may cause frostbite. Exposure could cause cardiac arrythmia and asphyxiation. See Notes. |
| PHYSICAL PROPERTIES | |
|
Boiling point: -84.4°C
Melting point: -155°C Relative density (water = 1): 1.44 Solubility in water: none Vapour pressure, kPa at 20°C: 4000 Relative vapour density (air = 1): 2.4 |
Octanol/water partition coefficient as log Pow: 0.64

| ENVIRONMENTAL DATA | |
|
|
| NOTES | |
|
To physicians: adrenergic agents are contraindicated. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. 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 23, Frigen 23, Halon 23 are trade names.
