0911 LEAD ARSENATE


IMPORTANT DATA
Physical State; Appearance Routes of exposure
ODOURLESS WHITE HEAVY POWDER The substance can be absorbed into the body by inhalation of
its dust and by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on heating above 270! producing
toxic fumes including arsenic, lead and their compounds. Evaporation at 20/C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly when
dispersed, especially if powdered.
Occupational exposure limits

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.
