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). 

Occupational exposure limits
MAK: Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004). 

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 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 at low levels could cause death. The effects may be delayed. 

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. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Solubility in water: none  This substance may be hazardous to the environment. Special attention should be given to water quality. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Temperature of decomposition unknown in literature.
Do NOT take working clothes home.
Card has been partly updated in October 2005.
