IMPORTANT DATA
Physical State; Appearance
BROWN POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes of arsenic and iron. 

Occupational exposure limits
TLV (as As): 0.01mg/m³ as TWA; A1 (confirmed human carcinogen); BEI issued; (ACGIH 2004).
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 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 irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system, liver, skin, kidneys and gastrointestinal tract. This may result in kidney impairment, neuropathy, severe gastroenteritis, degenerative liver damage and dermatitis. Exposure could cause death. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis, grey skin and hyperkeratosis. The substance may have effects on the nervous system, liver, cardiovascular system and respiratory tract. This may result in neuropathy, gangrene, degenerative liver damage and perforation of the nasal septum. 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 plants, air quality and water quality. It is strongly advised not to let the chemical enter into the environment.
