OSHA Respiratory Protection Medical Evaluations in 2026: What the Proposed Rule Actually Means for Your Program

If you have heard that OSHA is eliminating respirator medical evaluations for N95s and loose-fitting PAPRs, you have heard the right thing about the wrong timeline. OSHA proposed that change in July 2025. As of today — June 9, 2026 — it is still a proposal. The existing standard is the law. Every medical evaluation requirement under 29 CFR 1910.134(e) is in full force, and if your workers are using respirators without current medical clearance, you are exposed to a violation that generated more than 500 citations in fiscal year 2024 alone.

This piece explains where the rulemaking stands, what remains required today, why the proposed change may not survive in its current form, and what practical steps an EHS manager should take before the public comment window closes on July 6, 2026.

What OSHA Actually Proposed

On July 1, 2025, OSHA published a Notice of Proposed Rulemaking in the Federal Register (90 FR 28463) that would remove the medical evaluation requirement from 29 CFR 1910.134(e) for two specific respirator types: filtering facepiece respirators (FFRs) — your N95s, KN95s, P100 disposables — and loose-fitting powered air-purifying respirators (PAPRs).

OSHA’s rationale is substantive, not just deregulatory posturing. The agency argues that FFRs and loose-fitting PAPRs impose a significantly lower physiological burden than tight-fitting elastomeric respirators or SCBAs, and that the existing evidence base is insufficient to confirm that pre-use medical evaluations meaningfully prevent adverse health outcomes for workers wearing these two types. The agency estimated that eliminating these evaluations would save employers approximately $58.5 million annually and would eliminate roughly 1.2 million questionnaires per year.

That is the proposal. It is not the rule.

What the proposed rule does not touch:

Medical evaluations for tight-fitting half-face and full-face elastomeric respirators: still required
Medical evaluations for tight-fitting PAPRs: still required
Medical evaluations for supplied-air respirators and SCBAs: still required
Medical evaluations required by chemical-specific OSHA standards — asbestos (29 CFR 1910.1001), lead (29 CFR 1910.1025), silica (29 CFR 1910.1053), cadmium, formaldehyde, hexavalent chromium — those standards carry independent medical surveillance requirements that are entirely separate from this rulemaking and are not affected

If your workers wear tight-fitting elastomeric respirators, this proposed rule is a non-event for your program.

The Part of the Story Most EHS Managers Missed

On March 31 and April 1, 2026, OSHA consulted its Advisory Committee on Construction Safety and Health (ACCSH) on this proposed rule. The committee voted — five to four — to recommend that OSHA not proceed with the proposal and instead focus on identifying best practices and providing guidance to employers.

That vote was not a procedural formality. It reflects a genuine technical disagreement within the occupational safety community about what the medical evaluation actually does. The committee’s concern: the pre-use questionnaire is the only formal mechanism where a physician or licensed health care professional can identify an undiagnosed cardiac or pulmonary condition before a worker begins wearing a respirator. Remove the requirement for FFRs, and you remove the touchpoint entirely — not just for the workers who are clearly healthy, but for the 55-year-old with undiagnosed coronary artery disease who has been wearing an N95 without complaint for six months.

The same ACCSH meeting produced unanimous opposition to a related proposal to remove express HEPA filter requirements for substance-specific standards covering asbestos, cadmium, lead, and inorganic arsenic. The committee deadlocked on proposed changes to assigned protection factor requirements. Taken together, the ACCSH consultations tell you that OSHA’s broader respiratory protection modernization package is facing meaningful institutional resistance from the technical community, not just organized labor.

OSHA responded to the ACCSH vote by reopening the rulemaking record on June 3, 2026 (91 FR 33130) for an additional 30 days of public comment. That comment period closes July 6, 2026.

There is no finalization date on the calendar. There is no implementation deadline. The rule may be finalized, substantially modified, or withdrawn.

What Your Program Must Include Today

The 1910.134 standard has been in effect since April 1998. The medical evaluation requirements have not changed. Here is what remains required:

Before any employee uses a respirator on the job (whether the use is mandatory or voluntary with a tight-fitting respirator), the employer must provide a medical evaluation. The evaluation uses the OSHA Respirator Medical Evaluation Questionnaire (Appendix C of 1910.134) or an equivalent medical examination. A physician or other licensed health care professional (PLHCP) must review the questionnaire and provide written clearance. The employer pays for the evaluation. The employee’s medical information is confidential — the PLHCP gives the employer a recommendation, not a diagnosis.

Fit testing cannot happen until medical clearance is obtained. This is the sequence that most respiratory protection programs get wrong when they are running behind: they schedule fit testing, then realize they do not have current medical evaluations. You cannot reverse the order.

Medical evaluations must be repeated when: an employee reports signs or symptoms related to respirator use; the employee’s condition changes in a way that may affect respirator use; the employer, PLHCP, or supervisor observes conditions suggesting the evaluation should be updated; or the respirator type changes.

For employees using FFRs voluntarily — when the respirator is not required by OSHA or the employer — the employer must provide Appendix D of 1910.134 (the voluntary use information sheet). If the voluntary use involves a tight-fitting respirator, the full program including medical evaluation applies.

Retain medical evaluation records for the duration of employment plus 30 years per 29 CFR 1910.1020.

Why This Standard Is in Your Top Four Citation Risks

In fiscal year 2024, 29 CFR 1910.134 was the fourth most frequently cited OSHA standard — up from seventh in FY2023. That movement matters. Citation frequency is partly a function of inspection targeting, and respiratory protection has been getting increased attention in industries where silica, isocyanates, welding fume, and grain dust are present.

Within 1910.134, the medical evaluation provision (e)(1) generated 508 citations in FY2024. Most of those were not from employers who refused to conduct evaluations. They were from employers who had evaluations that were outdated, incomplete, or not documented to the standard’s requirements. An evaluation completed at hiring that was never repeated when the employee moved from an N95 to a half-face elastomeric respirator is not a compliant evaluation. An evaluation where the PLHCP filled out the questionnaire without reviewing it with the employee is legally questionable. An evaluation form stored with HR rather than the respiratory protection program file creates a documentation gap.

The exposure math is straightforward. At $16,550 per serious violation (the current maximum, frozen at the 2025 level through at least January 14, 2027 per OMB action canceling the 2026 inflation adjustment), a respiratory protection inspection at a facility with 20 workers lacking current medical evaluations can produce $331,000 in serious violation exposure. OSHA has authority to apply instance-by-instance citation authority for high-gravity respiratory protection violations. A willful violation maxes at $165,514 per instance.

A single willful OSHA violation costs up to $165,514. An iSi industrial hygiene assessment that catches it before the inspector does costs $4,050. That is a 41:1 return on a phone call.

The Specific Gap That Catches Programs Off Guard

The most common failure pattern in respiratory protection medical evaluations is not absence — it is staleness. An employer ran a proper medical evaluation program in 2021 when OSHA’s return-to-workplace enforcement activity was high. The evaluations were completed, documented, PLHCPs reviewed the questionnaires, clearances were issued. Then the program ran on autopilot for three years.

In those three years: two workers changed respirator types; one worker had a cardiac event and returned to work without any updated evaluation; the company added a new job classification requiring a half-face elastomeric respirator but the new hires received Appendix D instead of a full evaluation; the PLHCP who conducted the original evaluations retired and no one updated the arrangement.

None of these failures are obvious without a structured program audit. They are the kind of gaps that show up during an OSHA inspection and produce a cluster of citations that the employer genuinely did not see coming.

A respiratory protection program review — typically part of an industrial hygiene assessment — covers the program documentation, the medical evaluation records, the fit test records, and the training documentation as an integrated package. It tells you where the gaps are before an inspector does.

What to Do Before July 6, 2026

If you want to comment on the proposed rule: submit through regulations.gov, Docket No. OSHA-2025-0006. Comments close July 6, 2026. Whether you support the proposal, oppose it, or want to provide data on specific industries, this is the only open window in the current rulemaking cycle.

If you want to know whether your respirator program is current: the answer requires a look at your documentation, not a reading of the Federal Register. The proposed rule does not change today’s compliance requirements. The questions that matter for your program are: When were your medical evaluations last conducted? Are they properly matched to the respirator types each employee uses? Has your PLHCP relationship been documented? Do your fit test records follow the medical clearance sequence?

If your program has been running on autopilot for more than 18 months, there is a meaningful probability that something has drifted. The 508 citations under 1910.134(e)(1) in FY2024 came from programs that looked adequate from a distance.

iSi’s industrial hygiene assessment includes a written respiratory protection program review as a standard component. If you are in iSi’s COOP retainer, your program should have received an advisory on this rulemaking the week the June 3 notice published — that is what the retainer is for. If you are managing a respirator program independently and want a current-status review, that is a defined scope of work with a fixed price.

What Happens After July 6

OSHA will review the comments, consider the ACCSH recommendation, and decide whether to finalize the rule as proposed, modify it, or withdraw it. There is no statutory deadline for that decision. Given the 5-4 ACCSH vote against proceeding and the broader political complexity of a deregulatory health-and-safety rollback, the timeline for finalization — if it happens at all — is uncertain.

If the rule is eventually finalized, employers with FFR or loose-fitting PAPR programs will need to update their written respiratory protection programs to reflect the changed medical evaluation requirements. That update will not be complex, but it will need to happen within whatever compliance window OSHA establishes in the final rule.

Until then: your existing obligations under 29 CFR 1910.134(e) are the standard. The evaluation requirement is intact. The fit testing sequence is intact. The PLHCP relationship is intact. The record retention requirements are intact.

The proposed rule is worth tracking. It is not worth acting on.
