Important Data
|
Physical State; Appearance:
PURE: COLOURLESS CRYSTALS
;
TECHNICAL: BROWN FLAKES
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing toxic fumes including sulfur oxides, chlorine fumes.
Reacts with bases
causing toxic (sulfur dioxides fumes) hazard.
Attacks iron.
Occupational Exposure Limits:
TLV: 0.1 mg/m3 (as TWA), A4 (skin) (ACGIH 1997).
OSHA PEL: none
NIOSH REL: TWA 0.1 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin, and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance may cause effects on the central nervous system, blood
, resulting in irritability, convulsions and renal failure.
Exposure at high levels may result in death.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
|
|
Physical

|
Environmental
Data
|
The substance is very toxic to aquatic organisms.
This substance may be hazardous to the environment; special attention should be given to birds, and soil organisms.
In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms.
The substance may cause long-term effects in the aquatic environment.
Avoid release to the environment in circumstances different to normal use.
|
|
N O T E S
|
Use of alcoholic beverages enhances the harmful effect.
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Beosit, Chlortiepin, Cyclodan, Devisulphan, Endocel, Endosol, Hildan, Insectophene, Malix, Rasayansulfan, Thifor, Thimul, Thiodan, Thionex, and Thiosulfan are trade names.
