TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Not combustible. Heating will cause rise in pressure with risk of bursting. 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 |
|
AVOID EXPOSURE OF (PREGNANT) WOMEN!
|
|
| Inhalation |
Unconsciousness. Suffocation. (See Notes).
|
Ventilation.
|
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 |
See Skin.
|
Safety goggles, or eye protection in combination with breathing protection.
|
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.
|
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Ventilation. NEVER direct water jet on liquid. Do NOT let this chemical enter the environment (extra personal protection: chemical protection suit including self-contained breathing apparatus).
|
UN Hazard Class: 2.2
|
| EMERGENCY RESPONSE | STORAGE |
Transport Emergency Card: TEC (R)-20G39.
|
Fireproof if in building. Cool.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
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 and hydrogen fluoride. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation. INHALATION RISK: A harmful concentration of this gas in the air will be reached very quickly on loss of containment. EFFECTS OF SHORT-TERM EXPOSURE: Rapid evaporation of the liquid may cause frostbite. Exposure at high level may result in unconsciousness. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Animal tests show that this substance possibly causes toxic effects upon human reproduction. |
| PHYSICAL PROPERTIES | |
|
Boiling point: 6.9°C
Melting point: -105.5°C Relative density (water = 1): 1.4 Solubility in water, g/100 ml at 25°C: 0.89 Vapour pressure, kPa at 20°C: 180 Relative vapour density (air = 1): 4.1 |
|
| ENVIRONMENTAL DATA | |
|
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer. Avoid release to the environment in circumstances different to normal use.
|
| NOTES | |
|
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 133a, Genetron 133a are trade names.
