	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Unconsciousness. Suffocation.	Use ventilation.	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	See Skin.	Wear 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 refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COMPRESSED LIQUEFIED GAS. Physical dangers The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases including hydrogen chloride and hydrogen fluoride.	Formula: C₂H₂ClF₃ / H₂ClC-CF₃ Molecular mass: 118.5 Boiling point: 6.9°C Melting point: -105.5°C Relative density (water = 1): 1.4 Solubility in water, g/100ml at 25°C: 0.89 Vapour pressure, kPa at 20°C: 180 Relative vapour density (air = 1): 4.1

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation. Effects of short-term exposure Rapid evaporation of the liquid may cause frostbite. Exposure at high levels could cause unconsciousness.	Inhalation risk A harmful concentration of this gas in the air will be reached very quickly on loss of containment. Effects of long-term or repeated exposure Animal tests show that this substance possibly causes toxic effects upon human reproduction.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation.

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

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxic effects upon human reproduction.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
Avoid release to the environment because of 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.
