Respiratory Protection Program: The Complete OSHA 1910.134 Guide
Every element the standard requires — selection, medical evaluations, fit testing, training, voluntary use, and recordkeeping — with the CFR paragraph for each.
What Is a Respiratory Protection Program?
A respiratory protection program is the written, worksite-specific plan that OSHA requires under 29 CFR 1910.134(c) whenever respirators are necessary to protect employee health or are required by the employer. It must cover nine elements — respirator selection, medical evaluations, fit testing, use procedures, maintenance, breathing-air quality, two kinds of training, and program evaluation — and be administered by a designated, qualified program administrator. Respiratory Protection ranked #5 on OSHA's Top 10 most frequently cited standards in fiscal year 2025.
When OSHA Requires a Written Program
The trigger is 1910.134(c)(1): "In any workplace where respirators are necessary to protect the health of the employee or whenever respirators are required by the employer, the employer shall establish and implement a written respiratory protection program with worksite-specific procedures." Two words matter most:
- Written
A policy that lives in a manager's head does not satisfy the standard. OSHA inspectors ask for the document.
- Worksite-specific
A generic template is a starting point, not a finished program — procedures must reflect your hazards, your respirators, and your site, and be updated as workplace conditions change.
The program must be administered by a program administrator who is "qualified by appropriate training or experience that is commensurate with the complexity of the program" (1910.134(c)(3)). And the cost rule is explicit: the employer provides respirators, training, and medical evaluations at no cost to the employee (1910.134(c)(4)).
The 9 Required Program Elements
1910.134(c)(1)(i)-(ix) lists the provisions every written program must include, as applicable to your workplace. Use this as your audit checklist:
Respirator selection procedures
Evaluate the respiratory hazards, identify workplace and user factors, and select NIOSH-certified respirators appropriate to the exposure.
Medical evaluations
Every employee required to use a respirator must be medically evaluated before fit testing and first use — the element RespiratorTest.com handles end to end.
Fit testing procedures
Tight-fitting facepieces require a fit test with the same make, model, style, and size before first use and at least annually thereafter.
Procedures for proper use
Rules for routine use and reasonably foreseeable emergencies, including seal checks and prohibited conditions.
Maintenance schedules
Cleaning, disinfecting, storing, inspecting, repairing, and discarding respirators on defined schedules.
Breathing air quality
For atmosphere-supplying respirators: procedures to ensure adequate air quality, quantity, and flow.
Hazard training
Training employees on the respiratory hazards they are potentially exposed to in routine and emergency situations.
Respirator use training
Training on donning, doffing, limitations, and maintenance — repeated at least annually per 1910.134(k).
Program evaluation
Procedures for regularly evaluating the effectiveness of the program, including consulting the employees who wear the respirators.
Where the Medical Evaluation Fits — and Why Programs Fail There
Element (ii) is the sequencing gate for the whole program: "The employer shall provide a medical evaluation to determine the employee's ability to use a respirator, before the employee is fit tested or required to use the respirator in the workplace" (1910.134(e)(1)). No clearance, no fit test; no fit test, no respirator; no respirator, no work in the hazard area. Programs most often break down here because the medical step is the one element that traditionally required scheduling an outside clinic visit for every employee.
The mechanics are simpler than most administrators expect. The employer identifies a PLHCP — a physician or other licensed health care professional — who reviews either the OSHA Appendix C medical questionnaire or an exam that obtains the same information (1910.134(e)(2)). The questionnaire's mandatory portion contains 12 administrative items and 9 health question groups covering more than 50 conditions; a "yes" to any of questions 1-8 in Part A Section 2 triggers a follow-up examination (1910.134(e)(3)). The employer never sees the answers — only the PLHCP's written determination (1910.134(e)(6)).
"In respiratory protection programs that fall behind, the medical evaluation is almost always the bottleneck — not because it is medically complex, but because it was built around clinic appointments. Move that one element online and the other eight suddenly have a schedule they can keep."
— Dr. Nader Mikhail, MD, Medical Review Officer, RespiratorTest.com
Fit Testing and Training: The Annual Clock
Two program elements run on an annual cycle. Fit testing (1910.134(f)(2)): every employee using a tight-fitting facepiece must be fit tested with the same make, model, style, and size of respirator they will wear — "prior to initial use of the respirator, whenever a different respirator facepiece (size, style, model or make) is used, and at least annually thereafter." An additional fit test is required whenever a physical change could affect fit — facial scarring, dental changes, cosmetic surgery, or an obvious change in body weight (1910.134(f)(3)).
Training (1910.134(k)) must be comprehensive, understandable, and recur at least annually — covering why the respirator is necessary, its capabilities and limitations, donning and doffing, seal checks, maintenance, and recognizing medical signs that limit effective use. See the full respirator fit testing guide and respirator training requirements.
The medical evaluation has no fixed calendar interval — re-evaluation is event-driven (symptoms reported, PLHCP or supervisor request, fit-test observations, or changed workplace conditions, per 1910.134(e)(7)). Most programs still re-evaluate annually alongside the fit test so the two records renew together.
Voluntary Use and Appendix D
Where respirator use is not required, an employer may still permit employees to wear respirators at their request or allow them to bring their own — provided the use does not itself create a hazard (1910.134(c)(2)). Voluntary users must receive the information in Appendix D of the standard, which tells them to follow the manufacturer's instructions and to choose respirators certified by NIOSH.
| Scenario | Written program? | Medical evaluation? | Appendix D? |
|---|---|---|---|
| Required respirator use | Yes — full program | Yes, before fit test and use | — |
| Voluntary use, elastomeric/other respirators | Yes — elements ensuring medical ability and maintenance | Yes | Yes |
| Voluntary use, filtering facepiece (N95/dust mask) only | No (explicit exception) | No | Yes |
Source: 29 CFR 1910.134(c)(2)(i)-(ii), including the filtering-facepiece exception, and Appendix D.
Recordkeeping and Program Evaluation
1910.134(m) requires three record types, and they are the first things an inspector requests:
- Medical evaluation records
Retained per 29 CFR 1910.1020 — at least the duration of employment plus 30 years. Digital storage satisfies this; paper files in a clinic basement often don't survive it.
- Fit test records
Employee name, test type, respirator make/model/style/size, date, and result — kept until the next fit test.
- The written program itself
A current copy, reflecting today's workplace conditions — not the version from the year the program launched.
Finally, element (ix) closes the loop: the employer must conduct workplace evaluations as necessary to verify the program is implemented properly, and must consult the employees who actually wear the respirators to ensure they are being used correctly (1910.134(l)).

Respiratory Protection Program FAQs
What is a respiratory protection program?
A respiratory protection program is the written, worksite-specific plan OSHA requires under 29 CFR 1910.134(c) whenever respirators are necessary to protect employee health or are required by the employer. It must cover respirator selection, medical evaluations, fit testing, use procedures, maintenance, breathing-air quality, training, and program evaluation, and it must be run by a designated program administrator.
When is a written respiratory protection program required?
Whenever respirators are necessary to protect the health of the employee or whenever the employer requires respirator use (1910.134(c)(1)). For voluntary use, the employer must still implement the program elements needed to ensure the user is medically able and the respirator is kept clean — with one exception: employees whose only use is voluntary filtering facepieces (dust masks) need not be covered by a written program.
What are the required elements of a respiratory protection program?
OSHA 1910.134(c)(1) lists nine, as applicable: (1) respirator selection procedures; (2) medical evaluations of employees required to use respirators; (3) fit testing procedures for tight-fitting respirators; (4) procedures for proper use in routine and foreseeable emergency situations; (5) schedules for cleaning, disinfecting, storing, inspecting, repairing, and maintaining respirators; (6) procedures to ensure adequate breathing-air quality for atmosphere-supplying respirators; (7) training in respiratory hazards; (8) training in proper respirator use and maintenance; and (9) procedures for regularly evaluating program effectiveness.
Who can be a respiratory protection program administrator?
Anyone qualified by appropriate training or experience commensurate with the complexity of the program (1910.134(c)(3)). OSHA does not require a specific credential — in many companies it is a safety manager, industrial hygienist, or operations lead who understands the worksite's respiratory hazards and the program's procedures.
Does a respiratory protection program require medical evaluations?
Yes — medical evaluation is a required program element (1910.134(c)(1)(ii)), and 1910.134(e)(1) requires it before the employee is fit tested or wears a respirator at work. A physician or other licensed health care professional (PLHCP) reviews the OSHA Appendix C questionnaire or performs an equivalent exam, at no cost to the employee (1910.134(c)(4)).
Do voluntary N95 users need to be in the program?
Employees whose only respirator use is voluntary filtering facepieces (dust masks) do not need to be included in a written program, but the employer must still provide them the Appendix D information (1910.134(c)(2)). Voluntary users of other respirator types (e.g., elastomeric half-masks) must be covered by the program elements that ensure they are medically able to use the respirator and that it is cleaned, stored, and maintained safely.
How often must a respiratory protection program be updated?
As necessary to reflect changes in workplace conditions that affect respirator use (1910.134(c)(1)). In addition, fit tests must be repeated at least annually, training must recur at least annually, and the employer must conduct workplace evaluations as necessary to verify the program is being implemented properly (1910.134(l)).
How long must respiratory protection program records be kept?
Medical evaluation records must be retained per 29 CFR 1910.1020 — at least the duration of employment plus 30 years. Fit test records (employee, test type, respirator make/model/style/size, date, result) must be kept until the next fit test, and a written copy of the current program must be retained (1910.134(m)).
