Cal/OSHA Hearing Conservation Program Requirements (Title 8 §5097)
If a Cal/OSHA inspector walks into your California facility tomorrow and noise has been a known issue, the first paperwork request is predictable: your documented hearing conservation program.
If a Cal/OSHA inspector walks into your California facility tomorrow and noise has been a known issue, the first paperwork request is predictable: your documented hearing conservation program. Cal/OSHA enforces hearing conservation under Title 8 of the California Code of Regulations, primarily §5097, with related obligations in §§5098, 5099, and 5100. (This page covers general-industry workplaces under Cal/OSHA Article 105. Agriculture, construction, and oil and gas well drilling and servicing operations are exempt from §§5097–5100 and may have different noise requirements.) The standard is structurally similar to federal 29 CFR 1910.95, but the citation an inspector uses in California is Title 8, and the recordkeeping rules sit in their own section.
This page breaks down what those sections actually require, where facilities most often fall short, and how the pieces fit together. For a complete overview of how a program is built and run, see our hearing conservation program guide.
What Triggers the Requirement
Under Title 8 §5097(a), the obligation kicks in at an 8-hour time-weighted average (TWA) noise exposure of 85 dBA. That number is the action level. It is not the same as the permissible exposure limit, which is 90 dBA TWA. Once measured exposure equals or exceeds 85 dBA TWA for any employee, the full hearing conservation program is required for that employee, even though their exposure is still under the PEL. For more on the distinction between the two thresholds, see our OSHA noise exposure limits article.
Determining whether you cross the action level is a measurement question, not a paperwork question. That measurement is a noise survey (industrial hygiene work) and is the diagnostic step that precedes the program. If you have not yet had a noise survey, that is the place to start.
What §5097 (and the Surrounding Sections) Actually Require
§5097 covers most of the program structure, but the full set of obligations spans four adjacent sections. The table below maps each requirement to the regulation and what a California facility must have in place.
| Requirement | Where it lives | What the facility must do |
|---|---|---|
| Noise monitoring and sampling strategy | §5097(b) | Conduct representative monitoring of employees whose exposure may equal or exceed 85 dBA TWA. Repeat when equipment, processes, or controls change. |
| Employee notification | §5097(b)(5) | Notify each affected employee of their monitoring results. (Written notification is a defensible way to document that it was done, though §5097(b)(5) does not expressly require “in writing.” STS notification under §5097(d)(4) is expressly required in writing.) |
| Audiometric testing program | §5097(c) | Establish audiometric testing at no cost to the employee. Baseline audiogram preceded by 14 hours of quiet, then annual tests, performed by a licensed audiologist, physician, or a certified technician. |
| Standard threshold shift (STS) response | §5097(d) | Compare annual audiograms to baseline. When an STS is found (an average shift of 10 dB or more at 2,000, 3,000, and 4,000 Hz), notify the employee in writing within 21 days, refit hearing protectors, retrain, and review the program. |
| Hearing protectors | §5098 | Provide protectors at no cost, with multiple options, that reduce exposure to at most 90 dBA TWA (or 85 dBA TWA for employees who have experienced an STS). Train on use and care, and verify fit. |
| Training program | §5099(a) | Train every enrolled employee annually on three required categories: the effects of noise on hearing; the purpose, advantages, disadvantages, attenuation, selection, fitting, use, and care of hearing protectors; and the purpose of audiometric testing with an explanation of test procedures. Update content as equipment or processes change. |
| Access to information | §5099(b) | Make §5097 and related materials available to affected employees and their representatives. |
| Recordkeeping | §5100 | Retain noise exposure measurement records for at least 2 years; retain audiograms for the duration of the affected employee’s employment. Transfer records to a successor employer on sale or closure. |
This is the structural skeleton an inspector is working from. Each requirement has nuances the regulation spells out in detail; the table is the map.
Cal/OSHA vs Federal OSHA: What Actually Differs
The substance of California’s standard tracks federal 29 CFR 1910.95 closely. The practical differences are about who enforces, how citations get issued, and how the citation reads:
- Inspections are conducted by the Cal/OSHA Division of Occupational Safety and Health (DOSH), not federal OSHA.
- Citations reference Title 8, not 29 CFR. Your written program should cite the California sections.
- California’s penalty schedule and appeals process (Cal/OSHA Appeals Board) are separate from the federal system.
- California puts its hearing conservation recordkeeping in a standalone section (§5100). Federal 1910.95 keeps recordkeeping inside the same section. Easy to miss if you copied a federal template.
A program built against federal language and never updated for California will usually still pass on the substantive controls, then trip on the citations, the recordkeeping placement, or the missing California-specific notification language.
The Recordkeeping Rules That Trip People Up
§5100 sets two retention periods that are commonly confused with each other and with the federal medical-records rule:
- Noise exposure measurement records: at least 2 years.
- Audiometric test records: for the duration of the affected employee’s employment.
Some written programs imported from federal templates state “duration of employment plus 30 years” for audiograms, borrowing from the federal medical-records standard at 29 CFR 1910.1020. That blended language is a common deficiency we see in older California programs. State the California retention precisely. If you want to retain longer for risk reasons, that is a business decision, but the regulatory minimum should be stated correctly.
Practical Notes From the Field
A few patterns recur when we walk facilities and review existing programs.
- The “we already wear ear plugs” gap. PPE in use does not equal a documented program. We see this constantly: a facility hands out plugs at the supervisor’s discretion, employees wear them in the loud areas, and there is no written program, no enrollment list, no annual training, no audiometric coordination, and no hearing protector attenuation analysis. The program is the documentation around the practice, not the practice itself. Annual hearing conservation training and coordinated audiometric testing are part of what makes it a program rather than a habit.
- Tiered vs. blanket protection. Cal/OSHA’s tiered system distinguishes between employees above the action level (program-enrolled) and those above the PEL (mandatory protector use), with a separate layer for post-STS employees. Administratively, that tiering is more brittle than it sounds. Our standing recommendation is to require hearing protection at the 85 dBA action level for every exposed employee. It is simpler to enforce, easier to train, and more defensible if an inspector ever questions why a given person was not wearing protection.
- Programs that have not kept pace. When equipment changes, layout changes, or a new line is added, the monitoring assumptions in the program go stale. §5097(b) requires repeat monitoring when conditions change. The first thing an inspector asks once the written program is on the table is when it was last reviewed against the actual floor.
How CDMS Builds a Cal/OSHA-Compliant Program
Our team writes the program, builds the sampling strategy around your facility, delivers the annual training (or reviews and certifies your existing in-house training), structures the recordkeeping to the §5100 retention periods, and coordinates audiometric testing with qualified providers. We do not run the audiograms ourselves. We build the program around them so the results feed back into the right places, including the §5097(d) STS comparison and the §5099 retraining trigger.
The program lives inside an ongoing relationship rather than as a one-time deliverable, because §5097 requires the program to keep up with the facility. When equipment, headcount, or layout shifts, the program needs to shift with it.
