Important Data
|
Physical State; Appearance:
COLOURLESS
GAS
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The gas is heavier than air.
Chemical Dangers:
The substance decomposes
on heating at 550°C
producing
toxic and corrosive fumes
.
Reacts vigorously with water and moisture to form a highly acidic hydrates.
Attacks
glass
and most
metal
s.
Occupational Exposure Limits:
TLV: 0.1 ppm; 0.68 mg/m3 (skin) (ACGIH 2000).
MAK not established.
OSHA PEL: none
NIOSH REL: TWA 0.1 ppm (0.7 mg/m3) skin
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and through the skin.
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:
The substance
is severely irritating to
the eyes,
the skin and
the respiratory tract.
Inhalation of this gas may cause lung oedema (see Notes).
Rapid evaporation of the liquid may cause frostbite.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Animal tests show that this substance possibly causes malformations in human babies.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.

|
N O T E S
|
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
