Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: See 29 CFR 1910.1027, 1926.63 (FR 57; Sep 14, 1992) or IMIS C141. This code is for the exposure limits for any operations or sectors where the exposure limits in 1910.1027 or 1926.63 are stayed or otherwise not in effect. TABLE Z-2 . 0.2 mg/m3 TWA . 0.6 mg/m3 CEILING

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.01 mg/m3, 0.002 mg/m3 TWA; Appendix A2 (Suspected Human Carcinogen); BEI (TLV listed as Cadmium and Compounds, as Cd)

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): Lowest feasible concentration; Potential Carcinogen

Health Factors

Carcinogenic Classification:

International Agency for Research on Cancer (IARC): Group 1, carcinogenic to humans [62 KB PDF, 21 pages]

National Toxicology Program (NTP): Known to be a human carcinogen [115 KB PDF, 4 pages]

Potential Symptoms: Pulmonary edema; dyspnea, coughing, tight chest, substernal pain; headaches; chills, muscle aches; nausea, vomiting, diarrhea; anosmia; emphysema; proteinuria; mild anemia; (carcinogenic)

Health Effects: Cumulative kidney and lung damage (HE3) Cumulative lung damage (HE10)

Affected Organs: Respiratory system, kidneys, prostate, blood

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns
    maximum volume: 960 Liters
    minimum volume: 480 Liters
    maximum flow rate: 2.0 L/min (TWA)
    maximum volume: 30 Liters
    minimum time: 15 Minutes
    maximum flow rate: 2.0 L/min (Ceiling)
    current analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 2 (OSHA ID-121)
    sampling and analytical error: 0.10
    method classification: Fully Validated

  • alternate analytical method: Inductively Coupled Argon Plasma; ICP/DCP-AES
    method reference: 2 (OSHA ID-125G & ID-206)
    sampling and analytical error: 0.13
    method classification: Fully Validated
    note: If the filter is not overloaded, samples may be collected up to an 8-hour period when determining a PEL concentration. Analytical method does not distinguish between dust and fume.
