Respirator Medical Clearance: What OSHA Requires
The medical evaluation step, what OSHA's rule actually says, who needs it, what stays private, and when it has to happen again.

The short answer
Before an employee is fit tested or required to use a respirator on the job, OSHA requires their employer to provide a medical evaluation. The evaluation determines whether the employee can safely use a respirator under the work conditions involved. Medical evaluation and fit testing are different steps — medical evaluation comes first. See the full side-by-side comparison.
What "medical clearance" actually means
Respirators protect workers, but they also add breathing resistance and physiological burden. The medical evaluation exists to catch that risk before a respirator is assigned.
It's an OSHA requirement
The respiratory protection standard requires employers to provide a medical evaluation for employees who must use respirators on the job.
Reviewed by a PLHCP
A Physician or other Licensed Healthcare Professional determines clearance status and any limitations, based on the OSHA questionnaire and follow-up if needed.
You need documentation
The employer keeps the PLHCP's written recommendation and clearance result for records and audits — not the employee's detailed answers.
OSHA has proposed changes that could affect medical-evaluation requirements for certain respirator types (including some filtering facepieces and loose-fitting PAPRs). Until a final rule is issued and adopted, the current 29 CFR 1910.134 requirements — and any applicable state-plan rules — still apply.
What OSHA requires under 29 CFR 1910.134(e)
Employers must provide a medical evaluation to determine an employee's ability to use a respirator before the employee is fit tested or required to use it at work. The evaluation is completed using OSHA's Respirator Medical Evaluation Questionnaire (Appendix C), or an initial medical exam that obtains the same required information. See how the questionnaire works.
Confidentiality is part of compliance
Employers shouldn't review the employee's questionnaire responses. The PLHCP receives that information confidentially, and the employer retains only the written recommendation or clearance determination.
What the employer must be able to show
An audit-ready file set — not just a single clearance PDF — typically includes:
- check_circleProgram administration: a designated administrator and written procedures for your workplace
- check_circleMedical evaluation: a documented clearance determination from a PLHCP for each required user
- check_circleFit testing: records for each tight-fitting model/size used, as applicable
- check_circleTraining: records covering use, limitations, maintenance, and policy
- check_circleRe-evaluation tracking: a system that triggers additional evaluations when conditions change
Most compliance failures are process failures, not medical decisions — build a workflow that makes the right order automatic for supervisors and onboarding teams.
Who needs a respirator medical evaluation?
Any employee required to wear a respirator as part of their job needs a medical evaluation — whether that requirement comes from a hazard assessment, a client site policy, or your written respiratory protection program.
Common roles and environments
- Construction & trades: silica dust, concrete cutting, demolition, welding fumes, spraying
- Manufacturing & industrial: grinding, chemical handling, particulate exposure, shutdown maintenance
- Healthcare: required N95 use for airborne infectious-disease controls
- Utilities, remediation & cleaning: mold, asbestos, chemical disinfectants, confined spaces
- Emergency response: hazardous atmospheres, SCBA/supplied-air programs
Respirator types that commonly trigger clearance
- Filtering facepieces: N95/N99/N100/P100, when required by the employer
- Elastomeric respirators: half-mask and full-face
- PAPR: tight- and loose-fitting systems, depending on program and selection
- Supplied air / SCBA: higher-burden use cases with more stringent controls
If an employer requires an N95 as a condition of work, it's typically part of the respiratory protection program — medical evaluation comes first. Unsure whether your use is required or voluntary? See voluntary respirator use rules. Need N95-specific guidance? See N95 medical clearance.

How an evaluation actually works
Four steps, and a licensed clinician makes the decision in every single one.
-
1
The questionnaire
The employee completes the OSHA questionnaire on their own device, at any hour, usually in one sitting. No appointment is needed for this step.
-
2
Automated screening
The moment it is submitted, the answers are screened automatically. Screening can flag a response for closer review — it never decides that someone is not cleared.
-
3
Clinical review
A licensed healthcare professional reviews the submission. Some are decided on the questionnaire alone; others need follow-up information before a decision can be made.
-
4
The result is released
When the clinician releases it, the employer sees the outcome and any work restrictions that apply — and nothing else.
We don't publish a turnaround time, because we don't measure one and we won't promise a number we can't stand behind. What we can tell you is that no result reaches an employer until a person has released it.
When do you need an additional evaluation?
OSHA doesn't set one fixed expiration date — it focuses on triggers.
- monitor_heartSymptoms reported: the employee reports signs or symptoms related to respirator use
- record_voice_overPLHCP recommendation: the PLHCP indicates the employee should be reevaluated
- visibilityObserved problems: fit testing or program evaluation flags a need
- thermostatWork conditions changed: heavier workload, heavier PPE, or other factors that raise physiological burden
Your program interval determines when an employee is re-evaluated — commonly every 12 months. We track the date and flag it before it comes due.
FAQs: medical clearance and re-evaluation
Does ProTrain use the OSHA-required questionnaire, and who reviews it?
Yes. The evaluation is built around the OSHA-required respirator medical evaluation questionnaire. Automated screening runs the moment you submit, but it can only flag a response for closer review — it never decides that someone is not cleared. A licensed healthcare professional makes every clearance decision.
What happens if the PLHCP needs more information?
Sometimes a clinician needs clarification, or an in-person exam, before making a safe determination. If that happens, you'll be told exactly what's needed next. Once it's provided, the clearance determination is updated so your employer can proceed.
What does my employer see after I complete the evaluation?
Employers never see your health information — not the questionnaire, not your answers, not the clinical reasoning. They see the status of the evaluation, any work restrictions that apply, and what to do next.
How often do I need to redo the evaluation?
OSHA doesn't set one universal expiration date for every case. Your program's interval determines when you're re-evaluated — commonly every 12 months — and we track the date and flag it before it comes due.
This guide is for general information. Your requirements may vary based on your hazard assessment, respiratory protection program design, and any applicable state-plan rules.

Clinician-reviewed, not automated
Automated screening runs the moment an employee submits. It can flag a response for review, but it never decides that someone is not cleared — a licensed clinician makes every clearance decision.
