Physical dangers

Chemical dangers
Decomposes on heating. This produces toxic fumes of arsenic (see ICSC 0013). Reacts with acids. This produces toxic arsine gas (see ICSC 0222).

Formula: As₂Cu₃H₈O₁₂ / Cu₃(AsO₄)₂.4H₂O

Solubility in water: none

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance and the aerosol are irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system, digestive tract and circulatory system. This may result in severe haemorrhage, loss of fluids and electrolytes, collapse, shock and death. Exposure far above the OEL could cause death. The effects may be delayed.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the peripheral nervous system, skin, mucous membranes and liver. This may result in neuropathy, pigmentation disorders, perforation of the nasal septum and cirrhosis. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
