Important Data
|
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.
