Defense contractors and other federal contractors working at government facilities occupy a unique compliance position: they are private-sector employers subject to full OSHA jurisdiction, even when their worksite is a military installation or federal facility. This creates a compliance boundary that is frequently misunderstood — by contractors who assume the host agency's program covers them, and by government facility managers who assume contractors are someone else's problem. Both assumptions are wrong, and both can lead to OSHA citations.
Soundtrace supports defense contractors and federal contractors with automated in-house audiometric testing, audiologist review on every record, and complete 1910.95-compliant HCP documentation — independent of the host facility's program.
Defense contractor employees are private-sector workers. Their employer is the contractor, not the U.S. government. OSHA 29 CFR 1910.95 applies in full. The contractor is responsible for providing a compliant HCP. The host installation's military or federal agency program cannot substitute for the contractor's own compliance obligation.
The applicable OSHA noise standard depends on the type of work being performed — not where the work is located. On a single military installation, different contractor activities may fall under different standards simultaneously.
| Type of Work | Applicable Standard | Action Level | PEL | Notes |
|---|---|---|---|---|
| General industry operations (maintenance, manufacturing, depot work) | 29 CFR 1910.95 | 85 dBA TWA | 90 dBA TWA | Most common standard for defense contractors; covers audiometric testing, HCP, HPD |
| Construction activities (new construction, demolition, major renovation) | 29 CFR 1926.52 | 90 dBA TWA | 90 dBA TWA | Higher action level than 1910.95; hearing conservation program requirements differ from general industry |
| Shipyard employment (ship repair, shipbuilding at naval facilities) | 29 CFR 1915 Subpart B | 85 dBA TWA | 90 dBA TWA | Applies to shipyard activities at naval installations; similar HCP requirements to 1910.95 |
| Maritime operations (longshoring) | 29 CFR 1917/1918 | Varies | 90 dBA TWA | Applies to specific maritime activities; rarely applicable to most defense contractors |
Contractors performing maintenance work (replacing equipment, servicing HVAC, painting) generally fall under 1910.95, not 1926.52 construction. Construction standards apply to new construction, demolition, and major renovation — not ongoing maintenance and repair. OSHA interprets the activity, not the job title.
OSHA has jurisdiction over contractors at federal facilities and exercises it. The fact that a contractor's worksite is located within a military installation or government-owned facility does not create any special protection from OSHA enforcement.
OSHA and DoD have a Memorandum of Understanding (MOU) governing OSHA access to military installations for inspecting contractor worksites. OSHA inspectors may access installations subject to security and access requirements — which may require advance coordination, but do not prevent inspections.
Military installation safety offices that identify HCP deficiencies in contractor operations may refer the matter to OSHA for inspection. Installation safety offices have direct channels to the Department of Labor's Office of Federal Agency Programs (OFAP) and to regional OSHA offices. A contractor operating in noise-hazardous areas without an HCP is at real risk of referral.
| Compliance Element | Contractor Responsibility | Government Responsibility |
|---|---|---|
| HCP documentation | Contractor must maintain its own written HCP | Government program covers government employees only |
| Noise monitoring | Contractor must assess noise exposures for its own employees | Installation IH surveys are for government employees; contractor may use government data only with explicit authorization |
| Audiometric testing | Contractor must provide testing to its noise-exposed employees at no cost | Government testing covers government employees only |
| Professional supervision | Contractor must have its own professional supervisor per 1910.95(g)(3) | Government audiologist covers government employees; not available to contractor workers |
| OSHA 300 Log | Contractor maintains its own 300 Log for contractor employees | Government 300 Log for civilian employees is separate |
| HPD program | Contractor must provide HPDs to its noise-exposed employees at no cost | Government HPD issuance covers government employees only |
| Training | Contractor must provide annual 1910.95(k) training to its covered employees | Installation training covers government employees; cannot satisfy contractor's own obligation |
Common HCP-related SOW provisions include requirements that the contractor: comply with all applicable OSHA standards including 1910.95; submit a safety and health plan before work begins; complete baseline audiograms before contractor employees begin work in noise-hazardous areas; make audiometric records available to the contracting officer upon request; and provide evidence of professional supervisor arrangements.
The Federal Acquisition Regulation (FAR) requires contractors to comply with all applicable federal safety and health laws. OSHA violations can create contract performance issues and default risk in addition to direct citation exposure. FAR Clause 52.223-3 and related clauses establish baseline safety compliance obligations.
| Worker Type | Governing Standard | Who Runs the HCP | OSHA 300 Log |
|---|---|---|---|
| Military service members | DoDI 6055.12 only (exempt from OSHA) | Installation HRO / military medical | Not applicable |
| DoD civilian employees | OSHA 1910.95 + DoDI 6055.12 | Installation HCP (civilian component) | Federal agency OSHA 300 Log |
| Defense contractor employees | OSHA 1910.95 (private sector) | Contractor's own HCP | Contractor's own OSHA 300 Log |
| Subcontractor employees | OSHA 1910.95 (private sector) | Subcontractor's own HCP (prime may be responsible under multiemployer doctrine) | Subcontractor's own OSHA 300 Log |
Under OSHA's multiemployer worksite doctrine, a prime contractor may have HCP compliance exposure for subcontractor employees if the prime created, controlled, or had the ability to correct the hazard. Prime contractors should include HCP compliance requirements in subcontracts and verify subcontractor documentation before work begins in noise-hazardous areas.
| Compliance Gap | Why It Happens | Citation Risk |
|---|---|---|
| No baseline audiograms for employees in noise-hazardous areas | Contractor assumes installation's testing covers its employees | High — 1910.95(g)(2) violation; each uncovered employee is a potential separate violation |
| No professional supervisor arrangement | Contractor uses audiometer but has no audiologist/physician oversight | High — 1910.95(g)(3) violation; undermines validity of entire testing program |
| Missing annual audiograms for enrolled employees | Annual testing cycle not tracked; employees miss testing due to assignment changes | High — 1910.95(g)(6) violation |
| No STS determination or follow-up documentation | Results generated but not compared to baseline; no notification workflow | High — 1910.95(g)(7)/(8) violations; potential 300 Log violation |
| HPD adequacy not verified for actual exposure levels | Generic earplugs issued without attenuation verification | Moderate — 1910.95(j)(2) violation if NRR de-rated value is insufficient |
| No hearing conservation training records | Training conducted informally without documentation | Moderate — 1910.95(k)(1) violation |
Defense contractors performing general industry work are covered by OSHA 29 CFR 1910.95. Construction contractors fall under 29 CFR 1926.52. Shipyard contractors at naval facilities may fall under 29 CFR 1915. The standard is determined by the type of work, not the location.
No. The installation's program covers DoD military and civilian personnel only. Even if contractor employees are physically enrolled in installation audiometric testing, the contractor retains its independent OSHA 1910.95 obligation and can be cited separately.
Yes. OSHA inspects contractor worksites on military installations under an MOU with DoD and has full citation authority. Contractor sites are not shielded by their location on a federal facility. Installation safety offices may also refer contractor deficiencies to OSHA.
A compliant SOW should specify contractor responsibility for its own 1910.95-compliant HCP; baseline audiograms before work begins in noise-hazardous areas; independent record maintenance; records available for government audit; and professional supervisor arrangements satisfying 1910.95(g)(3).
In 2025, OSHA serious violation penalties reach up to $16,550 per violation. Willful or repeat violations can reach $165,514. Multiple HCP deficiencies can each be cited as separate violations with separate penalty calculations.
Soundtrace provides defense and federal contractors with automated in-house audiometric testing, audiologist review on every record, and complete 1910.95-compliant documentation — independent of the host installation's program.
