FIRE
|
Not combustible.
Gives off irritating or toxic fumes (or gases) in a fire.
|
|
In case of fire in the surroundings: use appropriate extinguishing media.
|
|

|
|
•Inhalation
|

Confusion.
Drowsiness.
Unconsciousness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
Artificial respiration may be needed.
Refer for medical attention.
|
|
•Skin
|
ON CONTACT WITH LIQUID: FROSTBITE.

Important Data
|
Physical State; Appearance:
COLOURLESS
GAS
OR HIGHLY VOLATILE LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The gas is heavier than air.
The vapour 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(hydrogen chloride ICSC 0163,phosgene ICSC 0007,hydrogen fluoride ICSC 0283,carbonyl fluoride ICSC 0633).
Reacts with powders of aluminium, zinc, magnesium and lithium shavings; granular barium.
Occupational Exposure Limits:
TLV: 1000 ppm (Ceiling value); A4; (ACGIH 2004).
MAK: 1000 ppm; 5700 mg/m3
Peak limitation category: II(2); Pregnancy risk group: C;
(DFG 2004).
OSHA PEL: TWA 1000 ppm (5600 mg/m3)
NIOSH REL: C 1000 ppm (5600 mg/m3)
NIOSH IDLH: 2000 ppm See: 75694
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.
Effects of Short-Term Exposure:
The liquid may cause frostbite.
The substance may cause effects on the
cardiovascular system
and
central nervous system
, resulting in
cardiac disorders
and central nervous system depression.
Exposure could cause lowering of consciousness.
See Notes.
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.

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.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The odour warning when the exposure limit value is exceeded is insufficient.
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 11, Frigen 11, Halon 11 are trade names.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
