Important Data
|
Physical State; Appearance:
RED CRYSTALS
OR POWDER.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing oxygen and toxic fumes.
Reacts
violently with
reducing agents
causing fire hazard.
Occupational Exposure Limits:
TLV: (as Pb) 0.05 mg/m3 as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: (as Pb) (Inhalable fraction);
Carcinogen category: 3B; Germ cell mutagen group: 3A;
(DFG 2004).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
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:
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
blood
,
bone marrow
,
central nervous system
,
peripheral nervous system
and
kidneys
, resulting in anaemia, encephalopathy (e.g., convulsions), peripheral nerve disease, abdominal cramps and kidney impairment.
Causes toxicity to human reproduction or development.
