IDLH (NIOSH) | 5 mg/m3, as As |
Excerpts from Documentation for IDLHs | No inhalation toxicity data are available on which to base an IDLH for calcium arsenate. Therefore, the revised IDLH for calcium arsenate is 5 mg As/m3 based on acute oral toxicity data in animals [Lehman 1951] and to be consistent with the revised IDLH for other inorganic arsenic compounds which have a revised IDLH of 5 mg As/m3. |
Explanatory Notes | NIOSH REL = ceiling of 0.002 as As, 15 min |
