Respirator readiness starts with your team.

Respirator medical evaluation and fit testing answer different questions. The medical evaluation assesses whether you can safely use the assigned respirator in the actual work conditions. A fit test checks the seal of a particular tight-fitting make, model, style and size on your face. Employers must arrange the medical evaluation before required respirator use or fit testing. A fit-test result alone does not supply medical clearance.

The employer selects a hazard-appropriate NIOSH-certified respirator and operates the written respiratory-protection program. Tight-fitting respirators require fit testing before initial use, at least annually, and when the facepiece changes or physical changes may affect fit. Loose-fitting respirators have different fit requirements. Voluntary use of a filtering facepiece also has a specific OSHA exception. Ask the employer which use case applies instead of treating every mask as the same program.

Send the employer’s respirator and work-condition information to the evaluating professional. Complete the confidential questionnaire accurately and discuss concerns directly with that professional. Complete any follow-up evaluation they require. The professional gives a written recommendation about ability to use the respirator, limitations and follow-up. Once the appropriate medical evaluation is complete, attend the fit test with the exact approved facepiece and accessories you will use.

Bring the employer authorization, respirator make, model, style and size, and any medical-evaluation documentation. Ask whether the employer or testing service supplies the facepiece. Tell the team about glasses, dentures, recent dental work, facial changes and symptoms with respirator use. Facial hair cannot interfere with the seal or valve function of a tight-fitting respirator. Follow the test provider’s instructions for the selected protocol before attending.

Ask the employer-service coordinator whether the requested screening can be provided at your worksite or on recurring dates. Send the coordinator the site, headcount, shifts, requested services and deadline. Confirm trained professionals, necessary equipment, privacy, accessibility, sample transport where relevant, result review, billing and a plan for workers who miss the event. Agree on the actual event dates and services before arranging employee attendance.

No universal spirometry requirement appears in OSHA’s general respiratory-protection standard. A PLHCP uses the required questionnaire or equivalent examination and orders additional evaluation when needed. Another exposure-specific standard may require testing. Spirometry, medical clearance and fit testing remain separate services.

The employer and qualified testing service must select a method allowed for the assigned respirator and required protection. Qualitative testing uses an approved sensory protocol; quantitative testing measures leakage. The two methods are not interchangeable in every situation.

The employer must ensure that the administrator can perform the selected fit-test protocol properly. That includes using and checking equipment and recognizing invalid results. OSHA does not require every fit-test administrator to be a physician. Medical evaluation is a separate step performed by a physician or another licensed health care professional whose scope permits that evaluation. Before booking, confirm the respirator make, model, style and size, the required test method and who will administer it. A medical clearance alone does not complete the fit test.

First complete the required medical evaluation. At the fit test, use the actual tight-fitting respirator make, model, style and size intended for work. Bring eyewear or other equipment that could affect its fit. The administrator explains the selected OSHA protocol and checks how the respirator sits on your face. Depending on the protocol, you breathe, speak and move your head or body while the test assesses leakage. Qualitative testing uses your response to an approved test agent. Quantitative testing measures leakage with equipment. A user seal check or a home video demonstration does not replace the formal fit test.

A physician or other licensed health care professional, called a PLHCP, reviews the required medical questionnaire or an examination obtaining equivalent information. The review considers the respirator, work effort, duration of use, protective clothing and heat or other conditions. A qualitative fit test uses a worker’s response to an approved test agent. A quantitative fit test measures leakage numerically. The permissible method depends on the respirator and required protection, rather than convenience alone.
