Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air
and may accumulate in low ceiling spaces causing deficiency of oxygen.
Chemical Dangers:
The substance decomposes
on heating
producing
phosgene
,
hydrogen fluoride
and
hydrogen chloride
.
Occupational Exposure Limits:
TLV not established.
Carcinogen category: 3B
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
irritates
the eyes
.
The substance may cause effects on the central nervous system and cardiovascular system
, resulting in narcosis and cardiac disorders.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the liver.

|
|
Environmental
Data
|
This substance may be hazardous to the environment; special attention should be given to
its impact on the ozone layer
.
It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
Avoid release to the environment in circumstances different to normal use.
|
|
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.
