What Are California's Respirator Requirements?
California workplaces follow Cal/OSHA Section 5144 (8 CCR 5144, "Respiratory Protection") — the state's own respiratory protection standard, not the federal 29 CFR 1910.134. Under 8 CCR 5144(e)(1), the employer must provide a medical evaluation before any employee is fit tested or wears a respirator; under 5144(e)(2), it is performed by a physician or other licensed health care professional (PLHCP) using the questionnaire in Section 5144's own Appendix C. Healthcare and related employers carry an additional California-only standard, 8 CCR 5199 (Aerosol Transmissible Diseases). The evaluation can be completed online: RespiratorTest.com administers the Appendix C questionnaire content in about 15 minutes for $22, reviewed by a California-licensed physician.
8 CCR 5144: California's Own Respiratory Protection Standard
California runs its own workplace safety program under Title 8 of the California Code of Regulations, enforced by Cal/OSHA. For respirators, the governing section is 8 CCR 5144. Its requirements parallel the federal respiratory protection standard — key passages, including the medical evaluation requirement in 5144(e)(1) and the annual fit test requirement in 5144(f)(2), are textually identical to their federal counterparts — but a Cal/OSHA citation names the California section. If your written program, training materials, or clearance records reference only the federal standard, a Cal/OSHA inspector will be looking for 5144.
The scale is national, but the citation is local: an estimated 5.0 million workers across U.S. workplaces wear respirators either occasionally or routinely (OSHA Technical Manual) — and every one of them working in California does so under Section 5144, not the federal rule.
Section 5144 requires, for every California workplace where respirators are necessary or required: a written respiratory protection program with worksite-specific procedures and a designated program administrator (5144(c)(1), (c)(3)); a medical evaluation before fit testing and first use (5144(e)); fit testing before first use and at least annually (5144(f)(2)); training; and recordkeeping (5144(m)). Under 5144(o), compliance with Section 5144's Appendices A, B-1, B-2, C, and D is mandatory — meaning California's Appendix C medical questionnaire is not optional paperwork; it is the required content of the medical evaluation. The program-level requirements mirror the nine federal elements covered in our respiratory protection program guide.
The 5144(e) Medical Evaluation — and How the Online Evaluation Satisfies It
8 CCR 5144(e)(1) requires: "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." Here is each requirement of paragraph (e), and how the online evaluation meets it:
- 5144(e)(2) — PLHCP review of the Appendix C questionnaire
The evaluation must be performed by a physician or other licensed health care professional using the information requested by Sections 1 and 2, Part A of Appendix C. RespiratorTest.com administers that questionnaire content online, and every submission is reviewed by Dr. Nader Mikhail, MD — a California-licensed physician (License #G88906).
- 5144(e)(3) — follow-up examinations when triggered
A yes answer to any of questions 1-8 in Section 2, Part A triggers a follow-up medical examination. About 98% of employees clear instantly; flagged cases receive individual physician review within 24 hours, including follow-up examination referral when required.
- 5144(e)(4) — confidential administration during working hours
The questionnaire must be administered confidentially, during normal working hours or at a convenient time and place. The online format satisfies this directly: employees answer privately, and employers never see medical responses — only the clearance determination.
- 5144(e)(6) — written medical determination
The employer must obtain a written recommendation from the PLHCP on the employee's ability to use the respirator. Every clearance certificate is that written determination, delivered digitally and stored for your records.
- 5144(m)(1) — records kept per 8 CCR 3204
California requires medical evaluation records to be retained and made available in accordance with 8 CCR 3204, California's employee medical records standard. The platform retains evaluation records digitally for 30 years.
"California didn't soften the federal rule — it adopted the same requirements nearly word for word and enforces them under its own letterhead. The medical evaluation your Cal/OSHA inspector asks about is cited 8 CCR 5144(e), and the questionnaire behind it is the same one I review every day."

8 CCR 5199: The California-Only ATD Standard for Healthcare
California healthcare and related employers carry a second respiratory standard that has no direct federal OSHA counterpart: 8 CCR 5199, Aerosol Transmissible Diseases. Under 5199(a)(1), it covers hospitals, skilled nursing facilities, clinics and medical offices, home health and hospices, EMS and medical transport, certain police operations, public health services, correctional facilities, homeless shelters, drug treatment programs, laboratories handling aerosol transmissible pathogens, and mortuaries.
For respiratory protection, 5199 does not replace 5144 — it builds on it. 5199(g)(2) requires covered employers to maintain a written respiratory protection program that meets the requirements of Section 5144, which pulls in the 5144(e) medical evaluation for every N95-wearing nurse, EMT, and lab tech. 5199(g)(4) lists the situations requiring respirators — among them entering airborne infection isolation rooms, performing procedures on airborne infectious disease cases, and transporting such cases in an enclosed vehicle — and 5199(g)(6)(B) requires fit testing at initial fitting, on any change of size, make, model, or style, and at least annually. Paragraph (h) adds ATD medical services: TB assessment available at least annually (5199(h)(3)) and the Appendix E vaccines offered within 10 working days of assignment (5199(h)(5)).
"I hold a California license, and a large share of the clearances I review are for California crews. The practical difference between 5144 and the federal standard is not the medicine — it is the citation on the inspector's paperwork. Do the evaluation properly and you satisfy both."

Cal/OSHA Respirator Requirements FAQs
What is Cal/OSHA 5144?
Cal/OSHA Section 5144 (8 CCR 5144, "Respiratory Protection") is California's own respiratory protection standard. It requires a written respiratory protection program (5144(c)), a medical evaluation before fit testing or respirator use (5144(e)(1)), fit testing before first use and at least annually (5144(f)(2)), and training. Its requirements parallel federal 29 CFR 1910.134, but California workplaces are cited under 8 CCR 5144, not the federal standard.
Is Cal/OSHA 5144 the same as OSHA 1910.134?
The core requirements match — key paragraphs such as the medical evaluation requirement (5144(e)(1)) and the annual fit test requirement (5144(f)(2)) are textually identical to their federal counterparts. The differences are the citation itself (California employers must comply with 8 CCR 5144), Section 5144's own mandatory appendices including its Appendix C medical questionnaire (5144(o)), medical recordkeeping under California's 8 CCR 3204 (5144(m)(1)), and California-only companion standards like 8 CCR 5199 for aerosol transmissible diseases in healthcare.
Are online respirator medical evaluations valid in California?
Yes. 8 CCR 5144(e)(2) requires the evaluation to be performed by a physician or other licensed health care professional (PLHCP) using the questionnaire content in Sections 1 and 2, Part A of Appendix C. Like the federal (e)(2) text it mirrors, 5144(e)(2) permits a questionnaire-based evaluation — it does not require an in-person visit. RespiratorTest.com administers that questionnaire content online, confidentially per 5144(e)(4), and every submission is reviewed by Dr. Nader Mikhail, MD, a California-licensed physician (License #G88906), who issues the written determination required by 5144(e)(6).
What is Cal/OSHA 5199 and who does it cover?
8 CCR 5199 is Cal/OSHA's Aerosol Transmissible Diseases (ATD) standard — a California-only standard with no direct federal OSHA counterpart. Under 5199(a)(1) it covers hospitals, skilled nursing facilities, clinics, home health, hospices, EMS and medical transport, certain police operations, public health services, correctional facilities, homeless shelters, drug treatment programs, laboratories, and mortuaries. Covered employers need a written respiratory protection program meeting Section 5144 (5199(g)(2)), annual fit testing (5199(g)(6)(B)), and ATD medical services including annual TB assessment (5199(h)(3)).
Who needs a respirator medical evaluation under Cal/OSHA?
Every California employee required to wear a respirator must receive a medical evaluation before being fit tested or using the respirator in the workplace (8 CCR 5144(e)(1)). Voluntary users of respirators other than filtering facepieces must also be medically evaluated; the one exception is employees whose only use is voluntary filtering facepieces (dust masks), who need the Appendix D information but no written program coverage (5144(c)(2)).
Does a medical evaluation done for 1910.134 satisfy Cal/OSHA 5144?
The medical content is the same: both standards require a PLHCP review of the same Appendix C questionnaire information, a written determination, and follow-up examinations on the same triggers. What matters in California is that your program documents compliance with 8 CCR 5144 — your written program, records (kept per 8 CCR 3204), and citations should reference the California standard. RespiratorTest.com evaluations obtain the Appendix C questionnaire information with PLHCP review, which is what 5144(e)(2) requires.
