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, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. 
 
EXPOSURE   AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation Unconciousness. 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.

IMPORTANT DATA
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. 

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 levels could cause unconsciousness. 

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


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
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  
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.
