Important Data
|
Physical State; Appearance:
CRYSTALS.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing toxic fumes including sulfur oxides, nitrogen oxides and sodium oxide.
The substance is a weak base.
Occupational Exposure Limits:
TLV not established.
MAK: 2 mg/m3 (Inhalable fraction); sensitization of skin (Sh);
Peak limitation category: II(2) Pregnancy risk group: D. See Notes
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
The substance
irritates the skin.
Effects of Long-Term or Repeated Exposure:

N O T E S
|
Health effects of exposure to the substance have been investigated, but none has been found.
The reaction with nitrosating agents can result in the formation of carcinogenic N-nitrosodiethylamine (DFG 2008).
Imuthiol is a trade name.
