Most occupational exposures to heavy metals are associated with metal working and machining, including but not limited to fabrication, smelting, welding, forges, foundries, grinding, refinishing and repair work. ​

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:

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
