Air Monitoring of Hexavalent Chromium In the Workplace

Reducing employer liability through workplace monitoring and worker protection.

A DQSI industrial hygienist can perform the following services:

  • Review workplace, equipment, materials, personnel, and controls
  • Monitor airborne concentrations of hexavalent chromium
  • Determine personal exposure levels
  • Assist in determining what level of training and personal protective equipment (PPE) needed (if any)
  • Prepare and maintain testing and certification records
  • Review liability and worker insurance requirements

Background

OSHA has determined, based upon the best evidence currently available, that at the current permissible exposure limit (PEL) for hexavalent chromium, workers face a significant risk to material impairment of their health. The evidence in the record for this rule making indicates that workers exposed to hexavalent chromium are at an increased risk of developing lung cancer. Occupational exposure to Cr6+ may result in asthma and damage to the nasal epithelial and skin.

29 CFR 1910.1026, “Occupational Exposure to Hexavalent Chromium”

  • Final rule establishes an 8-hour time-weighted average (TWA)
  • Exposure limit of 5 micrograms of hexavalent chromium per cubic meter of air (5 µg/m³)
  • Considerable reduction from the previous PEL (52 µg/m³ as hexavalent chromium)

Employer Requirements

  • Employer shall perform periodic monitoring at least every six months (when exposure exists)
  • Periodic monitoring at least every three months (when above PEL
  • Employer may discontinue monitoring only when PEL is below action level and verified over 7 day period
  • Employer shall perform additional monitoring when there has been any change in the production process, raw materials, equipment, personnel, work practices, or control methods
