Arizona ADOSH — Arizona's OSHA-approved State Plan administered by the Arizona Division of Occupational Safety and Health (ADOSH), Industrial Commission of Arizona — enforces hearing conservation requirements under Arizona Revised Statutes Title 23, Chapter 2. Like all State Plan states, Arizona must maintain occupational safety standards at least as effective as federal OSHA. For hearing conservation, Arizona ADOSH adopts 29 CFR 1910.95 by reference, meaning the substantive requirements are identical to federal OSHA. This guide covers what Arizona employers need to know about operating a compliant hearing conservation program under Arizona ADOSH's enforcement framework.
Soundtrace delivers audiometric testing and noise monitoring for employers across all 50 states including Arizona — ANSI S3.1-compliant and supervised by a licensed audiologist.
Arizona ADOSH Overview
Arizona ADOSH is an OSHA-approved State Plan that allows Arizona to operate its own occupational safety and health program in place of federal OSHA enforcement. State Plans must be at least as effective as federal OSHA. Arizona ADOSH is administered by the Arizona Division of Occupational Safety and Health (ADOSH), Industrial Commission of Arizona under Arizona Revised Statutes Title 23, Chapter 2.
Arizona semiconductor manufacturing (Intel, TSMC expansion, etc.) involves cleanroom environments that are typically below the action level, but facilities also contain utility areas, mechanical rooms, and support operations with significant noise. Area monitoring to confirm which worker classifications are at or above the action level is essential before assuming sub-action-level exposure across a semiconductor campus.
Hearing Conservation Requirements in Arizona
ADOSH adopts federal OSHA standards including 29 CFR 1910.95 by reference. No additional hearing conservation requirements. Arizona's major industrial sectors include semiconductor manufacturing, copper mining (MSHA for underground/surface mining), aerospace defense, food processing, and construction.
The substantive hearing conservation requirements under Arizona ADOSH are identical to federal 1910.95: the 85 dBA action level triggers the full six-element program, the PEL is 90 dBA, baseline audiograms must be established within 6 months of enrollment, annual audiograms are required within 12 months of the previous test, and STS detection triggers a specific chain of employer actions. See: audiometric testing for employers: complete OSHA guide.
Jurisdiction and Coverage
Arizona ADOSH enforces 29 CFR 1910.95 for both private sector employers and state/local government employees. Federal OSHA retains jurisdiction over federal government employees and contractors working in Arizona.
| Employer Type | Governing Agency | Hearing Conservation Standard |
|---|---|---|
| Private sector employers in Arizona | Arizona ADOSH | 29 CFR 1910.95 |
| State and local government employers | Arizona ADOSH | 29 CFR 1910.95 (adopted by reference) |
| Federal government employees | Federal OSHA | 29 CFR 1910.95 |
| Mining operations (underground/surface) | MSHA | 30 CFR Part 62 |
Enforcement and Penalties
ADOSH penalties: Serious up to $15,625. Willful/repeated up to $156,259.
Penalty amounts are adjusted annually for inflation. Arizona ADOSH enforcement priorities may differ from federal OSHA Area Office priorities — Arizona's dominant industries often drive local enforcement focus. Employers subject to Arizona ADOSH enforcement are not subject to concurrent federal OSHA jurisdiction for the same violations.

Key Noise-Exposed Industries in Arizona
The following industries in Arizona have significant occupational noise exposure profiles relevant to hearing conservation compliance: semiconductor manufacturing, aerospace defense, food processing, construction, copper smelting (MSHA boundary varies). Employers in these sectors should prioritize noise monitoring by job classification to confirm which workers meet the 85 dBA action level threshold.
Building a Compliant HCP in Arizona
The six required elements of an OSHA 1910.95 hearing conservation program apply identically in Arizona: noise monitoring, audiometric testing, hearing protection devices, annual training, recordkeeping, and access to information. There are no Arizona-specific additions to these requirements under Arizona ADOSH.
The most common compliance gaps found during Arizona ADOSH inspections mirror federal OSHA patterns nationwide: late or missing baseline audiograms, annual audiogram schedule failures, and inadequate HPD variety. See: OSHA HCP inspection guide.

Arizona ADOSH is Arizona's OSHA-approved State Plan. It adopts federal 29 CFR 1910.95 by reference, meaning the substantive hearing conservation requirements are identical to federal OSHA. Arizona ADOSH enforces 1910.95 for both private sector employers and state/local government employees.
Yes. The hearing conservation requirements — the 85 dBA action level, six required program elements, baseline and annual audiograms, STS detection and employer response requirements — are identical to federal 1910.95. The only difference is that Arizona ADOSH (rather than a federal OSHA Area Office) conducts inspections and issues citations for private sector employers in Arizona.
ADOSH penalties: Serious up to $15,625. Willful/repeated up to $156,259.
Underground and surface mining operations in Arizona fall under MSHA (30 CFR Part 62), not Arizona ADOSH or federal OSHA. Surface facilities at mining operations that are not engaged in mining activities may fall under Arizona ADOSH/"OSHA" jurisdiction. Employers in the mining sector should confirm jurisdiction for each worksite.
