IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE, AMORPHOUS POWDER

CHEMICAL DANGERS:
Upon heating, toxic fumes are formed. Reacts with acids to produce toxic arsine gas (see ICSC 0222).

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as As) 0.01 mg/m; 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 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the gastrointestinal tract, cardiovascular system, central nervous system, kidneys, resulting in severe gastroenteritis, loss of fluid and electrolytes, cardiac disorders, shock and kidney impairment. Exposure above OEL may result in 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 skin, mucous membranes, peripheral nervous system, bone marrow and liver, resulting in pigmentation disorders, perforation of nasal septum, neuropathy, lesions of blood cells and liver impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes malformations in human babies.
PHYSICAL PROPERTIES
Melting point: 1455C
Density: 3.62 g/cm
Solubility in water: none
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to water organisms. Avoid release to the environment in circumstances different to normal use.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response, Effects of long-term or repeated exposure.
