PHYSICAL STATE; APPEARANCE:
BLUE OR BLUISH-GREEN POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes of arsenic (see ICSC 0013). Reacts withacids releasing toxic arsine gas (see ICSC 0222).

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as As) 0.01 mg/m3; 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, 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 is irritating to the eyes and the respiratory tract. The substance may cause effects on the central nervous system, digestive tract, circulatory system , resulting in severe haemorrhagic, losses of fluids and electrolytes, collapse, shock and death. Exposure at low level 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 peripheral nervous system, skin, mucous membranes, and liver , resulting in neuropathy, pigmentation disorders, perforation of nasal septum, and cirrhosis. This substance is carcinogenic to humans.

PHYSICAL
PROPERTIES

Solubility in water:
none

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to water. It is strongly advised that this substance does not enter the environment.

N O T E S

Temperature of decomposition unknown in literature. Do NOT take working clothes home. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
