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.
The most current and conservative occupational exposure limits (OEL) are listed below:
TLV 0.00005 mg/m3 (inhalable fraction)
OSHA PEL TWA 0.005 mg/m3 (total fraction)
ACGIH TLV TWA 0.002 mg/m3 (respirable fraction)
ACGIH TLV 0.0002 mg/m3 (inhalable fraction); STEL 0.0005 mg/m3 (inhalable fractrion)
OSHA PEL TWA 0.05 mg/m3
