Important Data
|
Physical State; Appearance:
LIQUEFIED COMPRESSED GAS
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The gas is heavier than air
and may accumulate in low ceiling spaces causing deficiency of oxygen.
Chemical Dangers:
The substance decomposes
on contact with open flames or very hot surfaces,
producing toxic gases, including phosgene, hydrogen fluoride, hydrogen chloride, hydrogen bromide.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when 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
, resulting in
cardiac disorders
.
Effects of Long-Term or Repeated Exposure:
|
|
Physical
Properties
|
Boiling point: -4°C
Melting point: -160.5°C
Solubility in water:
none
|
Relative vapour density (air = 1): 5.7
Octanol/water partition coefficient as log Pow: 2.1
|
|
Environmental
Data
|
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
|
|
N O T E S
|
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.
