Frequently Asked Questions About Cadmium fume(g)(Z37.5-1970) Exposure

What is the legal OSHA PEL for Cadmium fume(g)(Z37.5-1970)?

Under OSHA 29 CFR 1910.1000 Table Z-1, the 8-hour Time-Weighted Average (TWA) Permissible Exposure Limit (PEL) for Cadmium fume(g)(Z37.5-1970) (CAS 0.1 mg/m3) is 0.3 ppm. In addition, NIOSH recommends a Recommended Exposure Limit (REL) of 1 ppm.

How do extended 10-hour and 12-hour shifts affect Cadmium fume(g)(Z37.5-1970) exposure limits?

Because OSHA PELs are formulated for 8-hour workdays, working 10-hour or 12-hour shifts reduces recovery time. Applying the standard Brief & Scala mathematical model reduces the allowable concentration by a Reduction Factor (RF = 0.700 for 10-hr, RF = 0.500 for 12-hr). For Cadmium fume(g)(Z37.5-1970), an 8-hr PEL of 0.3 ppm adjusts to half that value on a 12-hour shift.

What respirator and PPE is required when handling Cadmium fume(g)(Z37.5-1970)?

When atmospheric concentrations exceed the permissible limit up to 10× PEL, OSHA 29 CFR 1910.134 mandates a half-mask elastomeric respirator equipped with P100 / HEPA Particulate (Magenta). For dermal exposure, Nitrile or Neoprene Chemical Barrier are recommended.

What is the IDLH threshold for Cadmium fume(g)(Z37.5-1970)?

The Immediately Dangerous to Life or Health (IDLH) concentration established by NIOSH for Cadmium fume(g)(Z37.5-1970) is 3 ppm. Any entry into atmospheres at or above this concentration requires positive-pressure supplied air or Self-Contained Breathing Apparatus (SCBA).
