OSHA Respiratory Protection Requirements: Program, Fit Testing & Records
Quick Answer
Under 29 CFR 1910.134, employers who require or permit respirator use must have a written respiratory protection program that includes: procedures for selecting respirators, medical evaluations, fit testing, use (routine and emergency), maintenance and care, and training. The program must be administered by a designated program administrator and reviewed at least annually.
29 CFR 1910.134 — written program elements, medical evaluation requirements, annual fit testing, and the records you must maintain for every respirator user.
The most common respirator violation isn't wearing the wrong mask — it's missing documentation.
OSHA cites respiratory protection violations primarily for: no written program, no medical evaluation before use, no fit test records, and improper respirator selection. The program requirements exist because using the wrong respirator in the wrong way provides a false sense of protection.
Required Written Program Elements
Respirator Selection Procedures
How respirators are selected based on hazard type, airborne concentration, oxygen levels, and IDLH conditions
Medical Evaluation
Process for obtaining medical clearance before fit testing or use — must use OSHA questionnaire or equivalent
Fit Testing
QLFT or QNFT procedures for tight-fitting respirators; conducted before use and annually; records maintained
Procedures for Proper Use
Covers routine use, emergency use, IDLH atmospheres, and interior structural firefighting
Maintenance, Care & Storage
Cleaning, disinfecting, inspecting, repairing, and storing procedures; SCBA inspection frequency requirements
Training & Information
Why respirator use is necessary, limitations, proper use/fit/maintenance, emergency procedures, and medical signs of overexposure
Program Evaluation
Regular consultation with workers, annual review to assess program effectiveness
Medical Evaluation Process
Worker completes OSHA Questionnaire
Appendix C to 1910.134 — covers medical history, symptoms, current conditions relevant to respirator use
PLHCP reviews questionnaire
Physician or Licensed Health Care Professional reviews responses — may follow up with examination or questions
PLHCP provides written recommendation
Worker is approved, conditionally approved (specific respirator types only), or medically unable to use respirators
Fit testing may proceed
Only after medical clearance. Worker cannot be fit-tested or use a tight-fitting respirator without PLHCP clearance
Re-evaluation triggers
Worker reports symptoms, PLHCP recommends re-eval, program administrator observes symptoms, or worker requests it
Medical records are confidential
The PLHCP sends only the written recommendation to the employer — not the actual questionnaire responses or medical details. Employers must protect medical records per OSHA 1910.1020 and retain them for duration of employment plus 30 years.
Program Requirements by Respirator Type

Half-Face Air-Purifying Respirator Chemical vapors, welding fumes, pesticides | Required | Required | Required |
Full-Face Air-Purifying Respirator Higher concentration hazards, eye protection needed | Required | Required | Required |
Powered Air-Purifying (PAPR) Asbestos, lead, healthcare aerosol procedures | Required | Not required (loose-fitting) | Required |
SCBA / Supplied-Air IDLH atmospheres, confined space rescue, firefighting | Required | Required | Required |
Records to Maintain
| Record | Retention | CFR Citation |
|---|---|---|
| Written Respiratory Protection Program | Current version; review annually | 1910.134(c) |
| Medical Evaluation Records (PLHCP results) | Duration of employment + 30 years | 1910.1020 / 1910.134(m) |

Frequently Asked Questions
What does OSHA require for a respiratory protection program?
Under 29 CFR 1910.134, employers who require or permit respirator use must have a written respiratory protection program that includes: procedures for selecting respirators, medical evaluations, fit testing, use (routine and emergency), maintenance and care, and training. The program must be administered by a designated program administrator and reviewed at least annually.
When is a medical evaluation required before respirator use?
OSHA requires a medical evaluation before a worker is fit-tested or uses a respirator. The evaluation uses OSHA's mandatory questionnaire (Appendix C to 1910.134) or a licensed physician's equivalent. A PLHCP (Physician or Licensed Health Care Professional) must review responses and determine medical ability to use the respirator. Workers cannot be fit-tested until medically cleared.
How often is fit testing required under OSHA?
Fit testing is required before initial use of a tight-fitting respirator, annually thereafter, and whenever the worker reports changes that could affect fit (weight gain/loss >10%, dental work, facial scarring, etc.) or whenever the PLHCP or program administrator determines re-testing is necessary. Qualitative (QLFT) or quantitative (QNFT) fit testing methods are acceptable depending on the respirator protection factor required.
Do voluntary respirator users need a written program?
If workers voluntarily use filtering facepieces (dust masks, N95s) without being required to, employers must provide Appendix D of 1910.134 (information for voluntary users) but do not need a full written program. However, if any tight-fitting respirator (half-face, full-face, SCBA) is voluntarily used, a medical evaluation is still required. The distinction matters — check your policy carefully.
What records must employers keep for respiratory protection?
OSHA requires retaining: (1) medical evaluation records — duration of employment plus 30 years (per OSHA 1910.1020), (2) fit test records — until replaced by next annual fit test result, (3) written program — current version always on file. Employers must also maintain records of respirator inspections for SCBA and supplied-air respirators. Training records are best practice but not explicitly required by 1910.134.
