Important Data
|
Physical State; Appearance:
YELLOW
,
OILY
LIQUID
, WITH PUNGENT ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
toxic and corrosive fumes
including
hydrogen sulfide
and
sulfur oxides
.
The substance decomposes
on contact with
water
producing
hydrogen chloride
, sulfur dioxide and carbon dioxide.
Reacts
with
bases
,
oxidants
and
reducing agents
.
Attacks many metals.
Occupational Exposure Limits:
TLV: 0.1 ppm (ACGIH 2003).
MAK: IIb (not established but data is available) (DFG 2005).
OSHA PEL: TWA 0.1 ppm (0.8 mg/m3)
NIOSH REL: TWA 0.1 ppm (0.8 mg/m3)
NIOSH IDLH: 10 ppm See: 594423
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
through the skin
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:
The substance
is severely irritating to
the eyes
,
the skin
and
the respiratory tract
.
Inhalation of vapour at high concentrations 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:
|
|
Physical
Properties
|
Boiling point: 147-148°C
Relative density (water = 1): 1.7
Solubility in water:
none
|
Vapour pressure, kPa at 20°C: 0.4
Relative vapour density (air = 1): 6.4
|
|
Environmental
Data
|
|
|
N O T E S
|
Environmental effects from the substance have not been investigated adequately.
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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The name Perchloromethyl mercaptan is also used for a compound with CAS number 75-70-7 (CCl3SH).
