Respiratory protection begins with controlling the inhalation hazard and determining whether a respirator is necessary or required. When it is necessary or required, 29 CFR 1910.134 requires a written, worksite-specific program administered by a suitably trained program administrator covering selection, medical evaluation, fit testing, use, maintenance, training, and evaluation.
Provide medical evaluation before fit testing or required use. A tight-fitting facepiece needs a fit test before initial use, after make, model, style, or size changes, and at least annually; repeat it after a physical change affecting the seal. Voluntary use is not a loophole: determine it will not create a hazard and provide Appendix D information. A photo cannot prove medical ability, fit, concentration, or safe selection.
Who does this apply to?
- Use for general-industry respirator use under 1910.134; other sectors and substance-specific rules may add requirements.
- A written program applies when respirators are necessary to protect health or employer-required; required respirators, training, and medical evaluations are provided at no cost.
- Medical evaluation precedes fit or required use. Tight-fitting respirators need initial, change-triggered, and at-least-annual fit testing. Voluntary use still needs hazard review and Appendix D; the written-program exception is only for sole voluntary filtering-facepiece use.
Implementation Steps
Characterize the inhalation hazard
Identify contaminant, concentration, oxygen status, task duration, emergency conditions, and existing controls. Use exposure information and process knowledge, not cartridge appearance. Substance-specific or IDLH conditions may require a different level of protection. Record source, process state, worker position, sampling basis, uncertainty, control failure mode, and whether the task is routine, upset, spill, rescue, or maintenance. Implementation questions: who can stop the job when concentration or oxygen is unknown, and what qualified review is required before selecting equipment?
- List normal, upset, maintenance, spill, and rescue scenarios separately.
- Document why protection remains necessary and escalate unknown concentration, oxygen deficiency, or IDLH questions.
Select an appropriate approved respirator
Choose a configuration matching contaminant, concentration, work rate, atmosphere, face hazards, communication, and other PPE. Follow approval and manufacturer instructions and define change schedules; odor or a photograph cannot substitute for exposure or service-life analysis. The selection record should identify the approved configuration, protection basis, limitations, cartridge or canister information where relevant, work rate, eye or face interface, emergency boundary, and person who approved the rationale. Illustrative scenario: a solvent task changes from open transfer to a spill response; the routine selection is not copied into the emergency procedure until the atmosphere, duration, and response capability are reviewed.
- Record selection rationale, approval, protection basis, limitations, and PPE compatibility.
- Identify emergency and escape equipment separately from routine equipment.
Complete medical evaluation before fit or use
Provide evaluation before an employee is fit tested or required to use a respirator. The PLHCP uses the questionnaire or equivalent and gives the employer only information needed to administer the program. Follow restrictions or re-evaluation direction and protect confidentiality. Track only authorization status, date, limitations or follow-up needed for program administration, and the occupational-health contact. Escalate when authorization is incomplete, use changes, a worker reports difficulty, or a supervisor receives medical information that should move to the confidential custodian.
- Track completion and authorization without storing unnecessary medical detail in the supervisor file.
- Provide evaluation at no cost and revisit it when use or health changes require.
Fit test and teach the actual use
Fit test a tight-fitting facepiece before initial use, after make, model, style, or size changes, and at least annually; repeat after a physical change affecting fit. Train on donning, seal checks, limits, inspection, cleaning, storage, and emergency use. Facial hair crossing the seal is incompatible.
- Record facepiece, method, date, result, tester, and retest triggers.
- Require a demonstration and stop when a worker cannot obtain a seal or the task differs.
Operate, maintain, and monitor the program
Write routine and foreseeable emergency procedures, breathing-air controls, change schedules, cleaning, storage, inspection, repair, and replacement. The administrator evaluates use, worker feedback, exposure information, and barriers. Required use must not depend on personal equipment. Completion evidence should tie an observation to respirator identity, seal or donning behavior, condition, cleaning and storage, change decision, trainer or observer, and corrective follow-up. Stop and reassess when a seal cannot be obtained, a cartridge schedule is uncertain, breathing air is suspect, or the task moves outside the written program.
- Quarantine damaged or expired equipment and document disposition.
- Verify breathing-air quality when applicable and reassess after a process, exposure, PPE, or incident change.
Handle voluntary use narrowly
If the employer permits but does not require use, determine that it will not create a hazard and provide Appendix D. Implement program elements needed for medical ability and safe maintenance unless the only voluntary use is a filtering facepiece; keep the distinction clear. Document who made the required-versus-voluntary decision, the hazard information considered, the information provided to the user, and the conditions that would move the task into required use. A voluntary label should not be used to bypass an unresolved exposure or a supervisor instruction that effectively requires the respirator.
- Document required versus employer-permitted voluntary use.
- Do not present a filtering facepiece as protection for an unknown atmosphere or substitute for control.
Document planning checklist
Use this planning list to organize applicable records. Suggested owners and review triggers are workflow recommendations; the linked standards determine which documents and retention periods are legally required.
| Document / Record | Purpose | Owner | Review Cadence |
|---|---|---|---|
| Respiratory hazard assessment | Defines contaminant, concentration, oxygen, task, emergency scenario, and control basis. | Program administrator with industrial hygiene support | Before use and after process, material, exposure, or incident change |
| Written respiratory protection program | Controls selection, use, medical evaluation, fit testing, maintenance, training, and evaluation. | Suitably trained program administrator | At least annually and after a program or workplace change |
| Respirator selection and approval record | Links approved model, configuration, protection basis, limitations, and PPE compatibility. | Program administrator | When a contaminant, respirator, approval, or task changes |
| Medical evaluation authorization tracker | Shows whether employees completed the required evaluation without exposing confidential medical details. | Occupational health record custodian | Before fit testing or required use and after indicated re-evaluation |
| Fit-test and seal-use record | Documents facepiece identity, test method, date, result, and required retest triggers. | Qualified fit tester | Before initial use, at least annually, and after a fit-affecting change |
| Training and user-observation record | Documents limitations, donning, seal checks, cleaning, storage, emergency use, and demonstrated skill. | Supervisor or trainer | At assignment, change, observed gap, or program evaluation |
| Maintenance, change-schedule, and air-quality log | Tracks inspection, cleaning, changes, repairs, air checks, and quarantine. | Equipment custodian | At service and after a defect or task change |
Common Pitfalls
Fit testing before medical evaluation
The required sequence is medical evaluation before fit testing or required use. A completed fit-test form cannot substitute for medical authorization.
Annual means only initial paperwork
Tight-fitting facepieces need tests before initial use, at least annually, after make/model/style/size changes, and after physical changes affecting the seal.
Calling voluntary use unregulated
Permitted voluntary use still needs a hazard determination and Appendix D; medical ability and safe maintenance elements may still apply.

What the AI can and can't detect
OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.
What it can catch from a photo
- Missing or incorrect PPE that is visible in the frame
- Unprotected edges, open holes, and visible fall hazards
- Housekeeping, trip, and blocked walkway or exit hazards
- Visible electrical, struck-by, and equipment-guarding hazards
What a photo can't tell it
- Hazards hidden from view or anything outside the photo
- Exact heights, distances, weights, or measurements
- Training records, procedures, or how equipment is actually used
- Full legal compliance or an official OSHA pass/fail determination
