Important Data
|
Physical State; Appearance:
BLUE SOLID IN VARIOUS FORMS
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
toxic and corrosive fumes
including
sulfur oxides
.
The solution in water is a weak acid.
Attacks many metals in the presence of water.
Occupational Exposure Limits:
TLV: (as copper) 1 mg/m3 as TWA; (ACGIH 2004).
MAK: (as copper) (Inhalable fraction) 0.1 mg/m3
Peak limitation category: II(2); Pregnancy risk group: D;
(DFG 2004).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion
.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially, if powdered.
Effects of Short-Term Exposure:
The substance
is severely irritating to
the eyes
and
the skin
.
The aerosol
is irritating to
the respiratory tract
.
Corrosive on ingestion.
If ingested,
the substance may cause effects on the
blood
,
kidneys
and
liver
, resulting in
hemolytic anemia,
kidney impairment
and
liver impairment
.
Effects of Long-Term or Repeated Exposure:
Lungs may be affected by repeated or prolonged exposure to the aerosol.
The substance may have effects on the
liver
when ingested.
