impairment. Exposure above the OEL may result in death. The
effects may be delayed. Medical observation is indicated.
Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the mucous membranes,
skin, peripheral nervous system, liver and bone marrow, resulting
in pigmentation disorders, hyperkeratosis, perforation of nasal
septum, neuropathy, liver impairment, anaemia. This substance
is carcinogenic to humans. Animal tests show that this substance
possibly causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Sublimation point: 613/C Solubility in water: none
Density: 5.7 g/cm3
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.
NOTES
The substance is combustible but no flash point is available in literature.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
Refer also to cards for specific arsenic compounds, e.g., Arsenic pentoxide (ICSC 0377), Arsenic trichloride (ICSC 0221), Arsenic
trioxide (ICSC 0378), Arsine (ICSC 0222).
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
Card has been partly updated in October 2005 in section Effects of long-term or repeated exposure.
