Army IH Role:
IHs are typically involved in sampling (both area & personal) for heavy metal exposures. IH would also be involved in implementing controls to help minimize or eliminate heavy metal exposures.
Occupational Exposure Limits:
The most current and conservative occupational exposure limits (OEL) are listed below:
Beryllium
TLV 0.00005 mg/m3 (inhalable fraction)
Cadmium
OSHA PEL TWA 0.005 mg/m3 (total fraction)
ACGIH TLV TWA 0.002 mg/m3 (respirable fraction)
Hexavalent Chromium
ACGIH TLV 0.0002 mg/m3 (inhalable fraction); STEL 0.0005 mg/m3 (inhalable fractrion)
Lead
OSHA PEL TWA 0.05 mg/m3
