Important Data
|
Physical State; Appearance:
WHITE CRYSTALLINE POWDER.
Physical Dangers:
Chemical Dangers:
The substance decomposes
under the influence of
light
and
on heating to 450°C
producing very toxic fumes of mercury and
sulfur oxides
.
The solution in water is a medium strong acid.
Reacts with hydrogen halides.
Occupational Exposure Limits:
TLV: (as mercury) 0.025 mg/m3 (skin); A4 (not classifiable as a human carcinogen); BEI issued (ACGIH 2005).
MAK: (as Hg) 0.1 mg/m3
Peak limitation category: II(8);
sensitization of skin (Sh);
Carcinogen category: 3B; BAT issued;
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol,
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 when dispersed.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes,
the skin and
the respiratory tract.
Corrosive on ingestion.
The substance may cause effects on the
gastrointestinal tract
and
kidneys
, resulting in
tissue lesions
and
kidney damage.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
kidneys
,
central nervous system
and peripheral nervous system
, resulting in ataxia, sensory and memory disturbances, tremors, muscle weakness
and kidney impairment.

Physical
Properties
|
Decomposes below melting point at 450°C
Density: 6.5
g/cm3
|
Solubility in water:
reaction
Auto-ignition temperature: >450°C
|
|
Environmental
Data
|
The substance is very toxic to aquatic 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.
|
|
N O T E S
|
Depending on the degree of exposure, periodic medical examination is indicated.
Do NOT take working clothes home.
