Written Respiratory Protection Program Requirements

Written Respiratory Protection Program: OSHA 1910.134(c) Requirements (2026 Guide)

Published June 10, 2026 · Last updated July 27, 2026

Any workplace where respirators are required — or even provided for voluntary use — falls under the written respiratory protection program (WRPP) requirement at OSHA 29 CFR 1910.134(c). The written respiratory protection program is not optional documentation; it is the structural foundation that makes every downstream element of the respiratory protection standard enforceable. Safety managers, EHS coordinators, field supervisors, and industrial hygienists responsible for any respirator program — from a single spray-painter to a multi-site industrial operation — must have a site-specific written program in place before workers put on respirators.

This reference guide decodes OSHA 1910.134(c) line by line: what triggers the written program requirement, all 12 required elements, how selection, medical evaluation, fit testing, training, and program evaluation obligations are documented, and how voluntary-use programs differ. A worked example — a spray-painting contractor — walks through every documentation step using real NIOSH-approved equipment sold on this site.

Why this matters.
OSHA's most frequently cited respiratory protection violation is the complete absence of a written respiratory protection program — not a deficient one, an absent one. A Serious violation for no written program carries a penalty up to $16,550 per violation as of 2026; willful violations reach $165,514. More importantly, an employee using a respirator without a medical evaluation, fit test, or properly selected cartridge documented in a written program is potentially working in a false sense of protection. The written respiratory protection program under 1910.134(c) is the control document that connects hazard identification to the correct respirator, the medical clearance to use it, and the verified fit that makes it protective.

What triggers a written respiratory protection program

OSHA 1910.134(c)(1) states the written program requirement applies to all employers with a workplace where respirators are necessary to protect worker health or where respirators are provided for employee use. The regulation uses both triggers intentionally.

When respirators are "required"

A respirator is required when an OSHA standard mandates its use — for example, when airborne lead concentrations exceed the action level under 29 CFR 1910.1025, or when silica exposures exceed the permissible exposure limit under 29 CFR 1910.1053. A respirator is also required when the employer's own hazard assessment determines that engineering and administrative controls cannot bring exposures below the applicable occupational exposure limit (OEL). The governing OEL selection process — choosing between OSHA PELs, ACGIH TLVs, and NIOSH RELs — is explained in the ACGIH TLVs vs OSHA PELs respirator selection guide.

When respirators are "provided"

A respirator is provided when the employer makes respirators available to workers even though their use is not strictly compelled by any OSHA standard or the employer's own hazard assessment. The moment the employer provides respirators — even with the message that use is optional — the respiratory protection standard applies. The distinction between "provided but voluntary" and "required" determines the scope of the written program (see Part 6 on voluntary-use programs), but a written obligation exists in both cases.

The written requirement is literal

The standard specifies "written" — verbal instructions, on-the-job demonstrations, and even detailed training do not satisfy 1910.134(c). The program must be a retrievable document. It does not need to be paper — digital formats are acceptable (see FAQ 6) — but it must be a coherent, site-specific document that covers all applicable elements, not a binder of generic manufacturer literature.

The 12 required WRPP elements

1910.134(c)(1) requires the written program to cover procedures and elements for all required respirator use at the site. The 12 elements below reflect the complete enumeration drawn from 1910.134(c)(1) and the specific subsections that govern each element.

OSHA requires the written program to address "each applicable [element]" — if the facility does not have IDLH operations, element 12 may be abbreviated to state that IDLH procedures are not applicable at this site, with a brief explanation of how IDLH conditions are identified. Blanket omissions without explanation are a citation risk.

Respirator selection procedures in the written program

The selection-procedures section of the WRPP is the document that links each identified hazard to a specific, NIOSH-approved respirator class with a demonstrated adequate assigned protection factor (APF). It must be written with enough specificity that any competent person — not just the original author — can reproduce the selection decision.

Documenting OEL identification

For each chemical or particulate hazard, the WRPP selection section must document: (1) the chemical or contaminant identity, (2) the measured or estimated exposure concentration, and (3) the applicable OEL used as the decision standard. The ANSI/ASSP Z88.2 respiratory protection program standard provides the most complete guidance on OEL selection hierarchy for respirator programs. Per ANSI Z88.2, if multiple OELs exist for the same substance, the program should use the most protective applicable value. The ACGIH TLVs vs OSHA PELs respirator selection guide on this site covers that decision in detail.

Documenting APF calculation and MUC

The maximum use concentration (MUC) for any respirator is the product of the assigned protection factor (APF) and the applicable OEL: MUC = APF × OEL. The WRPP must document this calculation for each hazard and each respirator class specified. OSHA 1910.134(d)(3)(i) establishes the APF table — half-face APR (APF 10), full-face APR (APF 50), powered air-purifying with half-face or loose-fitting facepiece (APF 25/25), tight-fitting PAPR (APF 1,000), supplied-air (APF 1,000), and SCBA (APF 10,000). The selection section must show that the MUC for the selected respirator class equals or exceeds the measured or expected exposure concentration at the worksite.

Specifying NIOSH-approved respirators

The selection procedures must identify respirators by NIOSH approval (TC number). Generic references to "half-face respirator" without naming a NIOSH-approved model do not satisfy 1910.134(d)(1). For 3M full-face mask respirators, the relevant TC numbers are documented on the NIOSH approval label — a process explained in the NIOSH 42 CFR Part 84 respirator certification guide. The WRPP should list, for each hazard, the approved respirator by make, model, NIOSH TC number, and facepiece size per worker.

Cartridge selection and change-out schedule

For air-purifying respirators, the selection procedures must include the specific cartridge or filter type selected for each hazard. For chemical hazards with no IDLH or TLV-C concern, cartridge selection is governed by chemical class matching (OV, acid gas, organic vapor/P100, etc.). The WRPP must also reference the cartridge change-out schedule — when cartridges are replaced, per the respirator cartridge change-out schedule reference. For 3M respirator cartridges and filters, the cartridge change-out interval is documented in the WRPP selection section based on chemical service life data or a breakthrough-time calculation.

Medical evaluation and fit testing in the written program

Elements 2 and 3 of the WRPP — medical evaluation and fit testing — are procedural documentation requirements. The WRPP does not need to contain the actual medical questionnaire or fit test results; it must document the process by which those activities are administered, recorded, and maintained. Full procedural requirements for each are covered in the respirator medical evaluation requirements guide and the respirator fit testing guide.

Documenting the PLHCP designation

The medical evaluation procedures section of the WRPP must identify the physician or other licensed health care professional (PLHCP) designated to administer or supervise medical evaluations. The WRPP should document: PLHCP name, credentials, facility name and address, contact information, and the process by which the Appendix C questionnaire is distributed to workers and returned confidentially to the PLHCP. The WRPP must also document what triggers a re-evaluation: change in the worker's medical status, worker reports signs or symptoms related to respirator use, an OSHA inspector or supervisor observes signs of physiological distress, or a change in the work conditions that requires a different class of respirator.

Documenting fit testing protocol

The fit testing section of the WRPP must specify: (1) whether qualitative (QLFT) or quantitative (QNFT) testing is used, referencing the applicable Appendix A protocol; (2) the pass/fail threshold — for QLFT, a negative response to the challenge agent; for QNFT, a fit factor of at least 100 for half-face and at least 500 for full-face respirators; (3) who administers the tests and how their competency is established; (4) the annual testing schedule; and (5) how records are retained. Per 1910.134(f)(2), fit testing must be completed before the worker is required to wear the respirator in the workplace, whenever a different make, model, style, or size of respirator is used, and annually thereafter. Records must document worker name, test date, name of test conductor, make/model/style/size of respirator tested, and test results.

Training requirements: what 1910.134(k) requires in the written program

The WRPP training section must define the training process — not reproduce the training content itself. The section documents when training is conducted, by whom, using what format, and how completion is recorded.

Timing: initial and annual

OSHA 1910.134(k)(1) requires training before the worker is required to use a respirator in the workplace. Annual retraining is required unless the program administrator can demonstrate that the worker's knowledge and behavior from previous training are adequate. OSHA does not mandate a specific training format — in-person instruction, video-based training, and online completion are all permissible, provided the topics in 1910.134(k)(1) are covered and the training includes hands-on practice (donning, doffing, and fit checking cannot be accomplished in a purely passive format).

Required training topics

Per 1910.134(k)(1)(i)–(vii), training must cover: why the respirator is necessary and how improper fit, usage, or maintenance can compromise protection; the limitations and capabilities of the respirator; how to use the respirator effectively in emergency situations; how to inspect, put on and remove, use, and check the seal of the respirator; the procedures for maintenance and storage; how to recognize medical signs and symptoms that may limit or prevent the effective use of respirators; and the general requirements of the respiratory protection standard. The WRPP training section should list these topics as a checklist and document that training content addresses each one.

Training documentation requirements

The WRPP must describe the training record format. At minimum, records should capture: worker name, date of training, name of trainer, topics covered, and training method (in-person, video, written test score if applicable). Training records are among the records OSHA inspectors request first during a respiratory protection inspection — the WRPP must describe how and where they are retained. Per 1910.134(m)(1)(i), training records are not subject to the 30-year medical records retention requirement of 29 CFR 1910.1020, but they must be available to OSHA upon request.

Voluntary use programs and Appendix D

1910.134(c)(2) creates a reduced obligation for employers whose workers use respirators voluntarily — that is, the employer neither requires respirator use nor has determined through hazard assessment that it is necessary, but makes respirators available for workers who want them.

What qualifies as voluntary use

A respirator program is voluntary only when two conditions are met: (1) no OSHA standard compels respirator use for the applicable hazard, and (2) the employer's own hazard assessment has not determined that respirators are necessary to protect worker health. If either condition is not met, the program is mandatory and the full WRPP obligation under 1910.134(c)(1) applies. An employer who suspects that exposures may exceed an OEL but has not completed industrial hygiene sampling cannot default to calling the program voluntary — the failure to sample does not eliminate the compliance obligation.

Appendix D obligation for voluntary use

For voluntary-use programs, 1910.134(c)(2)(ii) requires only that the employer provide workers with the information in OSHA Appendix D to 1910.134. Appendix D covers: how the respirator should not be used as a substitute for engineering controls; what conditions may prevent safe use; proper care, maintenance, and storage; and when the wearer should stop using the respirator and seek medical assistance. Providing Appendix D does not require a formal written program document under 1910.134(c)(1), and no medical evaluation, fit testing, or training to the standard of 1910.134(k) is required for voluntary-use programs. The one exception is filtering facepiece (N95/P100 disposable) voluntary use — Appendix D must be provided, but there is no fit test requirement.

Voluntary use exceptions

Two categories of voluntarily used respirators remain subject to the full 1910.134 program even if the employer considers use voluntary: supplied-air respirators and self-contained breathing apparatus (SCBA). The complexity and consequence of incorrect use of these devices means OSHA does not permit a reduced-program approach regardless of whether use is mandatory or voluntary. An employer providing SCBAs for voluntary use must maintain a full written program, medical evaluation, fit testing, and training program covering those devices.
