OSHA requires respiratory protection training for all employees who are required to wear respirators in the workplace, as well as those who voluntarily use respirators (filtering facepieces/N95s used voluntarily have reduced requirements). This includes construction workers exposed to silica or dust, painters, welders, healthcare workers, firefighters, HAZWOPER workers, asbestos/lead abatement workers, laboratory workers, and anyone exposed to harmful airborne contaminants above OSHA Permissible Exposure Limits (PELs).

OSHA requires annual respiratory protection retraining - at a minimum once every 12 months. Retraining is also required when changes in workplace conditions or respirator types make previous training obsolete, when workers demonstrate inadequate knowledge, or when any other situation arises that requires retraining. Annual fit testing is also required separately.

A fit test is a procedure to verify that a specific make, model, and size of respirator forms an adequate seal on a worker’s face. OSHA requires fit testing before initial use and at least annually thereafter. There are two types: (1) Qualitative fit testing (QLFT) – a pass/fail test using taste or smell agents (like Bitrex or saccharin); (2) Quantitative fit testing (QNFT) – uses instruments to measure actual leakage into the facepiece. Online training does not replace the hands-on fit test, which must be done in person.

Air-purifying respirators (APRs) filter contaminants from ambient air using cartridges, canisters, or filters. They include N95 filtering facepieces, half-face and full-face respirators, and powered air-purifying respirators (PAPRs). Supplied-air respirators (SARs) provide clean breathing air from an external source through a hose or self-contained tank (SCBA). SARs are required in oxygen-deficient atmospheres (below 19.5%) and in IDLH (Immediately Dangerous to Life or Health) conditions where APRs are insufficient.

OSHA requires employers to establish a written respiratory protection program when respirators are required in the workplace. The program must include: procedures for selecting respirators, medical evaluation requirements, fit testing procedures, proper use and maintenance, training provisions, air quality standards for supplied-air systems, and program evaluation procedures. A designated program administrator must oversee implementation.

Before an employee can be fit tested or use a respirator, OSHA requires a medical evaluation to determine the worker’s ability to wear a respirator. The evaluation uses the OSHA Respirator Medical Evaluation Questionnaire (Appendix C to 29 CFR 1910.134) and is reviewed by a physician or other licensed health care professional (PLHCP). Workers with conditions like lung disease, heart disease, or claustrophobia may be restricted from certain respirator types.

NIOSH (National Institute for Occupational Safety and Health) tests and certifies respirators to ensure they meet minimum performance standards. OSHA requires that employers only provide NIOSH-certified respirators. Common NIOSH certifications include N95 (filters at least 95% of airborne particles), N99, N100, R95, P95, and P100 for particulate respirators, and specific approvals for gas/vapor cartridges. Always verify respirators bear the NIOSH approval label.

IDLH stands for Immediately Dangerous to Life or Health – an atmosphere that poses an immediate threat to life, would cause irreversible health effects, or would impair a worker’s ability to escape. Examples include oxygen levels below 19.5%, high concentrations of toxic gases, and fire/explosion hazards. In IDLH conditions, OSHA requires the highest level of respiratory protection: either a full-face pressure-demand SCBA or a combination full-face SAR with an escape SCBA.

Yes. eTraining’s Respiratory Protection Training covers all OSHA-required knowledge-based training topics. However, employers must still provide hands-on fit testing in person (qualitative or quantitative), medical evaluations through a licensed healthcare professional, and site-specific instruction on the particular respirators and hazards in their workplace. Online training fulfills the educational component of OSHA’s training requirements.
