Chrome plating tanks, stainless steel welding operations, and chromate-based coating processes all generate hexavalent chromium (Cr(VI)), a confirmed human carcinogen classified as Group 1 by the International Agency for Research on Cancer. Under 29 CFR 1910.1026, the permissible exposure limit for Cr(VI) in general industry is 5 micrograms per cubic meter of air (µg/m3) as an 8-hour TWA, with an action level of 2.5 µg/m3. Cleaning crews who sweep, vacuum, or wipe surfaces in chrome plating shops or heavy fabrication facilities with stainless steel welding can be exposed to Cr(VI) in settled dust at concentrations that exceed both thresholds.
The carcinogenicity of Cr(VI) means that OSHA classifies inadequate controls as a Serious hazard with high probability of causing serious physical harm. The 2026 penalty ceiling is $16,550 per Serious violation and $165,514 per Willful or Repeat. Medical surveillance violations, particularly failure to provide required examinations to workers with confirmed exposure at or above the action level, have been cited as Willful in OSHA enforcement cases.
What the Standard Requires
1910.1026 follows the same structural pattern as the lead and silica standards: a PEL with an action level, a hierarchy of controls, specific housekeeping prohibitions, and a medical surveillance program triggered by the action level. The standard at 1910.1026(j) explicitly prohibits dry sweeping, dry brushing, or the use of compressed air to clean Cr(VI)-contaminated surfaces unless these methods are shown to be infeasible.
| Requirement | Specific Obligation | CFR Section |
|---|---|---|
| PEL and action level | PEL: 5 µg/m3 TWA; Action Level: 2.5 µg/m3; STEL: 50 µg/m3 (15-min) | 1910.1026(c) |
| Housekeeping prohibition | No dry sweeping, dry brushing, or compressed air cleaning of Cr(VI)-contaminated surfaces unless infeasible | 1910.1026(j)(1) |
| Housekeeping methods | HEPA-equipped vacuums, wet sweeping, or other methods that minimize exposure | 1910.1026(j)(2) |
| Exposure assessment | Initial assessment; full monitoring when initial assessment indicates exposure at or above AL | 1910.1026(d) |
| Medical surveillance | Required for workers exposed at or above AL for 30 or more days/year; includes OSHA-directed medical questionnaire and examination | 1910.1026(l) |
| Respirator program | Required when engineering controls cannot maintain exposure below PEL; full 29 CFR 1910.134 program required | 1910.1026(g) |
| Training | Annual training covering Cr(VI) health effects, exposure controls, and medical surveillance | 1910.1026(m) |
The medical surveillance program under 1910.1026(l) requires the employer to provide medical examinations at no cost to the worker. The examination includes a medical and work history focused on Cr(VI) exposure, a physical examination of the respiratory system, and a physician's written opinion. Workers exposed above the action level for 30 or more days per year must receive this surveillance upon initial assignment, annually, and upon termination of employment.
Who It Applies To
The standard applies to general industry employers with workers occupationally exposed to Cr(VI). The primary industries are hard and decorative chrome plating operations, chromate pigment manufacturing, stainless steel welding (which generates Cr(VI) in the welding fume), aerospace maintenance shops, and facilities that apply chromate conversion coatings to aluminum. Cleaning contractors assigned to these facilities need to assess whether their housekeeping tasks bring workers into contact with settled Cr(VI) dust or residue on surfaces and equipment.
The OSHA hexavalent chromium topic page identifies the industrial sectors with the highest Cr(VI) exposure potential and lists OSHA's enforcement priorities for the standard.
What the Inspector Looks At
An OSHA inspection in a chrome plating or welding facility will focus on housekeeping methods as a primary leading indicator of overall Cr(VI) program quality. An inspector who observes dry sweeping in an area with visible chromate residue will cite immediately. The inspection will then proceed to verify the air monitoring program, medical surveillance enrollment, and training records.
| Inspector Check | Common Deficiency | Citation Risk |
|---|---|---|
| Dry sweeping prohibition | Dry brooms, dry rags, or compressed air used to clean Cr(VI)-contaminated surfaces | Serious, $16,550 |
| Exposure monitoring records | No initial exposure assessment; monitoring records not current after process changes | Serious |
| Medical surveillance enrollment | Workers exposed at or above AL for 30+ days/year not enrolled in medical surveillance program | Serious to Willful |
| Respirator fit-test records | Respirators provided without fit testing; APF calculations not documented | Serious |
| Training records | Annual Cr(VI) training not completed; workers cannot describe safe housekeeping methods | Serious |
Common Citations and What They Cost
The most common Cr(VI) citation for cleaning operations is 1910.1026(j)(1): use of dry sweeping or compressed air for surface cleaning in Cr(VI)-contaminated areas. This is a Serious citation at up to $16,550. Where the employer cannot show an infeasibility analysis for wet methods or HEPA vacuuming, the citation is difficult to contest. Grouped with medical surveillance failures at 1910.1026(l), the total initial citation package for a single chrome plating shop inspection can approach $50,000 to $80,000 before informal settlement negotiations. Willful designations for medical surveillance failures have been upheld in OSHA Review Commission cases where employers had actual knowledge of worker exposure levels and failed to provide required examinations.
Tradeoffs and Operator Reality
Chrome plating and heavy fabrication accounts pay premium cleaning rates precisely because the compliance infrastructure is expensive. A BSC taking on a chrome plating shop needs: HEPA-equipped vacuums certified for Cr(VI) applications, a respiratory protection program, a medical surveillance vendor relationship, and annual Cr(VI) training documentation. The all-in compliance cost for a 4-person crew at a single chrome plating account can run $3,000 to $5,000 in year one, including equipment, medical exams, and training administration. Bidding this account at standard janitorial rates is a formula for operating at a loss or cutting corners on compliance. The SOW must price the compliance infrastructure as a separate line item, and the client must understand what they are paying for. Clients who push back on the compliance cost should be shown the OSHA citation history for their industry and the penalties that result from inadequate housekeeping controls in Cr(VI) environments.
What to Put in the SOW and Training Matrix
The SOW for chrome plating, stainless steel fabrication, or coating operations should specify the housekeeping methods (HEPA vacuum model and filtration standard, wet method protocols), the PPE requirements (respirator type, glove specification), the medical surveillance program enrollment criteria, and the training schedule. It should also define the boundary between the BSC's scope and the client's engineering controls, such as ventilation maintenance, which affect the Cr(VI) concentrations the cleaning crew encounters.
