Important Data
|
Physical State; Appearance:
SLIGHTLY OILY, COLOURLESS LIQUID
, WITH PUNGENT ODOUR.
Physical Dangers:
The vapour is heavier than air.
Chemical Dangers:
May explode on heating and on shock.
The substance decomposes
on heating and
under influence of light
producing toxic fumes including hydrogen chloride and nitrogen oxides.
Reacts violently with alcoholic sodium hydroxide, sodium methoxide, propargyl bromide, aniline+heat.
Occupational Exposure Limits:
TLV: 0.1 ppm; 0.67 mg/m3 (as TWA); A4 (ACGIH 1998).
MAK: 0.1 ppm, 0.68 mg/m3
Peak limitation category: I(1)
(DFG 2006).
OSHA PEL: TWA 0.1 ppm (0.7 mg/m3)
NIOSH REL: TWA 0.1 ppm (0.7 mg/m3)
NIOSH IDLH: 2 ppm See: 76062
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
Tear drawing.
The substance
irritates strongly the eyes, the skin and the respiratory tract.
Inhalation of vapor may cause lung oedema (see Notes).
Exposure above the OEL may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:

N O T E S
|
Depending on the degree of exposure, periodic medical examination is indicated.
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 inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT take working clothes home.
