Who Can Perform Respirator Fit Testing in California?
A facility that needs respirator fit testing usually starts with a practical question: who do we call?
A facility that needs respirator fit testing usually starts with a practical question: who do we call? The answer matters because Cal/OSHA does not accept “we had a fit test” as a checkbox. The agency expects the test administered correctly per a specific protocol, the records kept, and the person running the test trained to recognize what a failed seal looks like.
Here is what California regulations actually require of the person conducting a respirator fit test, the difference between clinical and consulting providers, and what to ask before you hire anyone.
What Cal/OSHA Requires of a Fit Tester
Title 8 CCR §5144 (California’s respiratory protection standard) does not require a state-issued certification to perform fit testing. What it requires is that the test be conducted per the protocols in Appendix A, by a person competent enough to follow them.
In practice, that competence means three things:
Knowledge of the protocol.
The qualitative fit test using Isoamyl Acetate, saccharin, Bitrex, or irritant smoke is a defined procedure with specific steps. So is the quantitative fit test using equipment like the PortaCount. Each protocol has equipment, test agents, fit-test exercises, and pass/fail criteria spelled out in the regulation.
Ability to recognize a failed test.
A fit tester needs to know what a leak looks like on each exercise. If an employee detects the test agent during the bending exercise but not during normal breathing, the test fails. The employee needs a different respirator model and a retest.
Documentation skill.
§5144 requires a specific set of records for each test: employee name, date, respirator make, model, size, test type, and pass/fail. A test that wasn’t documented properly is, for Cal/OSHA purposes, a test that didn’t happen.
What §5144 does not require: a license, a state-issued credential, or membership in any organization. There is no “California Fit Tester Certificate.” Anyone competent in the Appendix A protocol can administer the test if their employer has set them up to do it correctly.
That is a low bar to meet on paper. In a Cal/OSHA inspection, it is not.
Who Actually Performs Fit Testing
In California, fit testing is delivered by three types of providers. They do different things.
Occupational Health Clinics
Concentra, Examinetics, and similar clinical providers run fit tests as one service inside a broader occupational medicine offering. The employee drives to the clinic, gets tested, and leaves with a fit-test card.
Clinics are a fit for facilities that:
- Already send employees to that clinic for physicals, drug screens, or medical evaluations.
- Have a handful of employees and don’t want a vendor on site.
- Want the fit test only, not the program or training that surrounds it.
What clinics typically do not deliver: the written respiratory protection program required by §5144, employee training on respirator use, or the analysis that tells you whether your respirator selection actually matches your chemical exposures.
EHS Consulting Firms
Consulting firms like CDMS deliver the test as one component of the broader program required by §5144. A typical engagement bundles four things:
- The written respiratory protection program: the site-specific document Cal/OSHA expects every covered employer to have on file.
- Training for all respirator users, classroom plus hands-on, covering the topics the standard requires.
- The fit test itself, performed on site for employees who use tight-fitting respirators.
- Coordination of the medical evaluation that has to be completed before the fit test happens.
The fit-test card is the same fit-test card. What changes is that the rest of the regulatory package is built around it.
Internal Staff
Some employers train their own people to run fit tests. This is common at hospitals and large industrial sites with a full-time safety officer. For most California facilities under 200 employees, the math doesn’t work. The equipment, training, and recordkeeping overhead exceed the cost of bringing a qualified vendor on site once a year.
Why On-Site Matters
The single most useful question to ask a provider is: do you come to us?
Sending employees to a clinic in batches sounds efficient until you count the time. A facility with 25 respirator users and a one-hour round trip to the nearest clinic burns roughly a full workday of labor that doesn’t show up on the fit-test invoice. Multiply that by the annual fit-test requirement and the math gets uncomfortable.
On-site fit testing keeps employees on the floor. Our team drives to your facility with the kit, the protocol, and the documentation, and runs testing through your shift. Production interruptions are limited to the few minutes each employee spends going through the test exercises.
CDMS work is field-service from end to end. We come to you. There is no version where you drive to our office.
What to Ask Before You Hire a Provider
Before you sign with any fit-test provider, ask these four questions:
Do you provide the written respiratory protection program, or only the test?
If you don’t already have a §5144 program on file, a test-only provider leaves you with a partial deliverable. The written program is what a Cal/OSHA inspector asks to see first.
What protocol do you use, and is it Cal/OSHA-recognized?
Qualitative protocols (Isoamyl Acetate, saccharin, Bitrex, irritant smoke) and quantitative protocols (PortaCount or equivalent) are listed in §5144 Appendix A. Anything outside that list is not a compliant test.
How do you document each test?
A passing test that lives only in someone’s notebook isn’t an inspection record. You want a per-employee record that names the respirator make, model, and size, the date, the protocol, and the pass/fail result.
What happens if an employee fails?
Failed employees aren’t done with respiratory protection. They need a different respirator and a retest. A provider who plans for failure has a process for it. A provider who doesn’t will leave you to figure it out.
These four questions separate providers who treat fit testing as a transaction from providers who treat it as a regulatory deliverable.

What CDMS Delivers
CDMS performs qualitative respirator fit testing per Title 8 §5144 Appendix A, on site, anywhere in California. For N95s and other filtering facepieces that means a saccharin or Bitrex protocol; the isoamyl acetate protocol is used where the respirator carries an organic vapor cartridge. Our consultants develop the written program first, train your respirator users, then run the fit test in the same engagement so the documentation chain runs unbroken from program to per-employee record.

Trusted throughout California
BSY started working with CDMS last year after our in-house EHS person departed the company. CDMS reviewed our existing operational permits as well as any additional Federal, State and Local regulations that could apply and helped us to create a comprehensive compliance calendar to track regulatory deadlines and submittal due dates. The CDMS team does an excellent job of tracking everything and can be relied upon to complete the forms accurately and assist with submittals, allowing me to focus on our business.
