IMPORTANT DATA

Physical State; Appearance
BLUE SOLID IN VARIOUS FORMS

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.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point (decomposes): 110°C Density: 2.3 g/cm³ Solubility in water, g/100 ml at 0°C: 31.7	The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish. It is strongly advised that this substance does not enter the environment.

NOTES

The apparent melting point caused by loss of crystal water is given.
