PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE HEAVY POWDER

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating above 270° producing toxic fumesincluding arsenic, lead and their compounds.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Pb3(AsO4)2) 0.15 mg/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 dust 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 , the skin and the respiratory tract . The substance may cause effects on the gastrointestinal tract and nervous system.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the gastrointestinal tract, nervous system, kidneys, liver and blood. This substance is carcinogenic to humans. May cause reproductive toxicity in humans.
