Respirator Medical Clearance: What Employers Need to Know
Every employee who wears a tight-fitting respirator in a California facility has to be medically cleared before they put it on for the work.
Every employee who wears a tight-fitting respirator in a California facility has to be medically cleared before they put it on for the work. Not after. Not during the same visit as the fit test. Before. This sequence is built into Cal/OSHA Title 8 §5144 and 29 CFR 1910.134, and it is the single most common scheduling problem we see when employers try to stand up a respirator program quickly.
Medical clearance comes first, before either fit testing or training. Fit testing and training both have to be complete before the worker uses the respirator on the job; they are often done in the same visit. If any of the three is missing, the worker is not authorized to wear the respirator, and a Cal/OSHA inspector will find the gap as soon as they ask for records.
Why Medical Clearance Has to Come First
Wearing a respirator is physical work. A tight-fitting mask increases breathing resistance, traps heat, and can make a heart, lung, or anxiety condition worse. Cal/OSHA §5144(e) and the federal 1910.134(e) require employers to determine, through a medical evaluation, that the employee is physically and psychologically able to use the respirator safely before assigning it.
The clearance also drives the fit test. A worker medically restricted from a tight-fitting half-mask may need a powered air-purifying respirator (PAPR) or a loose-fitting hood instead. You cannot fit-test someone for a respirator they have not been cleared to wear. For a complete walk-through of how the program fits together, see our California respirator fit testing program guide.
What the OSHA Medical Evaluation Questionnaire Asks
Cal/OSHA §5144 incorporates the OSHA medical questionnaire (Appendix C of 1910.134) as the default screening tool. It is the form most California employers will use. The questionnaire has two mandatory parts that every respirator user completes, regardless of respirator type:
Demographic and respirator-use information. Age, height, weight, contact information, the type of respirator to be worn, the work the respirator will be used for, and the expected duration of use per shift and per week.
Health history. A structured set of yes/no questions covering:
- Heart and circulatory conditions (history of heart attack, angina, high blood pressure, irregular heartbeat)
- Lung and respiratory conditions (asthma, COPD, emphysema, tuberculosis, lung cancer, pneumothorax, chest injuries or surgery)
- Other conditions that can affect respirator tolerance (seizures, diabetes, claustrophobia, hearing or vision problems that interfere with the mask seal, back or muscle problems that limit movement, allergic reactions that affect breathing)
- Current medications that may interfere with respirator use
- Whether the employee has ever worn a respirator before, and if so, whether they had any problems
Full-facepiece and supplied-air respirators trigger additional history questions specific to higher-effort use. The employee completes the questionnaire confidentially. The employer never sees the answers. The completed form goes directly to a physician or other licensed health care professional (PLHCP).
The PLHCP’s Role
Cal/OSHA §5144 requires the medical evaluation to be reviewed by a PLHCP. In practice, this is a physician, a physician assistant, or a nurse practitioner whose state license allows them to perform employee health evaluations.
The PLHCP reviews the questionnaire and issues a written recommendation to the employer. It states whether the employee is medically able to use the respirator, whether any restrictions apply (time limits, respirator-type limits, follow-up exam), and whether a re-evaluation is needed. The employer sees only the clearance decision, not the medical answers.
When a Physical Exam Is Required
Most employees clear on the questionnaire alone and move directly to fit testing. A physical exam is required when something flags a concern: a reported heart or lung condition, a positive answer the PLHCP needs to verify, or a respirator type that demands a higher level of physical capability. The PLHCP, not the employer, makes that call.
The exam is a separate appointment with an occupational health provider. Cal/OSHA §5144 also triggers a new exam when the employee, the supervisor, or the PLHCP determines one is needed because of new symptoms, changed workplace conditions, or information that surfaced during fit testing or actual respirator use.
How CDMS Handles the Medical Clearance Workflow
When CDMS builds a respiratory protection program for a California facility, the medical evaluation is a defined step in the sequence:
We provide the OSHA medical questionnaire to each employee on your respirator roster, with the confidentiality framing the standard requires.
Completed questionnaires are routed to a PLHCP for review. Individual answers do not come back to the employer.
The PLHCP returns a written clearance decision: cleared, cleared with restrictions, or physical exam required.
When a physical exam is required, we coordinate the appointment with an occupational health provider. CDMS does not perform physical exams in-house.
Once clearances are complete, fit testing is scheduled. For the on-site portion, see what a respirator fit test actually involves.
Quote requests for this work routinely come in by headcount of medical evaluations: “Please submit quote for 20 medical evaluations” is a verbatim example from our inbox. That phrasing tracks the gating sequence. Medical evaluations get scoped first because nothing else can happen until they are done.
When Medical Clearance Can Be Discontinued
This question comes up regularly. An employee changes roles, moves to a job that does not require a respirator, or the facility eliminates the respirator-required task entirely. Does that employee still need medical clearance?
The short answer is no. Cal/OSHA §5144 requires medical evaluation for employees who wear a respirator. Once a worker is no longer assigned to respirator use, the medical evaluation requirement ends for that worker, and §5144(e) expressly lets the employer discontinue evaluations at that point. Document the change: a note in the personnel file indicating the date the assignment ended, signed by the supervisor or program administrator. That documentation explains why a former respirator user’s records stop.
If the same employee is later reassigned to a respirator-required task, the clearance has to be re-established before they wear the respirator again. The clock resets.
What Triggers a Repeat Medical Evaluation
§5144 does not set a fixed annual medical exam. Instead, it requires the initial evaluation before respirator use and an additional medical review when:
- The employee reports symptoms during respirator use (shortness of breath, chest pain, dizziness, wheezing)
- A supervisor or the program administrator observes signs that the employee cannot wear the respirator safely
- The PLHCP, the fit-test administrator, or the employee themselves recommends a re-evaluation
- A change in workplace conditions (new chemicals, higher exposure levels, hotter or more strenuous work) increases the physiological burden of respirator use

Trusted throughout California
BSY started working with CDMS last year after our in-house EHS person departed the company. CDMS reviewed our existing operational permits as well as any additional Federal, State and Local regulations that could apply and helped us to create a comprehensive compliance calendar to track regulatory deadlines and submittal due dates. The CDMS team does an excellent job of tracking everything and can be relied upon to complete the forms accurately and assist with submittals, allowing me to focus on our business.
