Hearing Conservation SOW Requirements for Government Contracts

Government contract statement of work hearing conservation requirements for noise-hazardous federal contracts

Government contracts involving noise-hazardous work — construction, maintenance, depot operations, facility services — should include hearing conservation program requirements in the Statement of Work (SOW) or Performance Work Statement (PWS). This isn’t just contractually sound; it’s the mechanism by which the government verifies that contractor employees working on its facilities and projects are protected under OSHA 1910.95. This guide covers what HCP SOW provisions should include, which FAR clauses are relevant, and what documentation the government should require.

Soundtrace supports defense contractors and federal contractors with automated in-house audiometric testing, licensed audiologist review, and complete 1910.95-compliant documentation — designed to satisfy government SOW documentation requirements at contract award and throughout performance.

Why SOW Language Matters

A contract SOW that requires HCP compliance creates contract performance obligations in addition to OSHA obligations. A contractor who fails to maintain a compliant HCP faces contract performance deficiency findings, potential cure notices, and in severe cases, termination for default — on top of OSHA citation risk.

What HCP SOW Provisions Should Include

Effective HCP SOW language covers all six elements of 29 CFR 1910.95 at an appropriate level of specificity. Boilerplate stating only “comply with applicable OSHA standards” is insufficient — it doesn’t create measurable deliverables or documentation requirements that contracting officers and CORs can verify.

  • Noise hazard identification: The contractor shall assess noise exposures for all employees assigned to noise-hazardous work areas and notify employees of exposures at or above 85 dBA TWA
  • HCP establishment before work begins: A written HCP meeting all requirements of 29 CFR 1910.95 shall be established before employees begin work in areas where noise exposures may reach or exceed 85 dBA TWA
  • Baseline audiograms before exposure: Baseline audiograms completed before employees begin work in noise-hazardous areas, or within the timeframe permitted by 1910.95(g)(2)
  • Professional supervisor identification: The contractor shall identify, in HCP documentation submitted to the COR, the name and credentials of the licensed audiologist, otolaryngologist, or physician serving as professional supervisor per 1910.95(g)(3)
  • Annual audiogram completion: Annual audiometric testing completed for all enrolled employees within the one-year anniversary of their baseline per 1910.95(g)(6)
  • STS notification compliance: When a Standard Threshold Shift is identified, the contractor shall notify the affected employee within 21 days per 1910.95(g)(8)(ii)
  • Records available for government audit: Audiometric records maintained and available to the Contracting Officer or COR within 5 business days of written request
  • HPD provision and adequacy verification: Appropriate HPDs provided at no cost to employees; attenuation adequacy verified for actual exposure levels
  • Annual training: Annual hearing conservation training per 1910.95(k) provided and records maintained

Relevant FAR Clauses

FAR ClauseRelevance to HCPApplication
FAR 52.223-3 (Hazardous Material)General baseline safety compliance obligationIncorporated by reference in most contracts; establishes OSHA compliance obligation
FAR 52.236-13 (Accident Prevention)Construction contracts safety program requirementApplies to construction contracts; requires contractor safety plan including OSHA compliance
Project-specific safety clauseHCP-specific requirements beyond FAR baselineAdded under CO authority; most effective vehicle for substantive HCP SOW requirements

DoD Contracts: DoDI 6055.12 Requirements

For contracts performed at DoD installations, SOW language should specify compliance with DoDI 6055.12 in addition to OSHA 1910.95. Key additions:

  • Baseline audiograms before assignment to noise-hazardous duty (DoDI requires this before exposure; OSHA allows 6 months)
  • PAR hearing protector fit testing for contractor employees with documented exposures above 95 dBA TWA per DoDI 6055.12 Change 1 (November 2023), where the government determines this requirement applies
  • Coordination with the installation HRO for noise area designations and posted noise zone compliance
Whether DoDI 6055.12 applies to contractors at DoD installations is a contracting decision that must be made deliberately. Including DoDI requirements in the SOW makes them contract obligations — enforceable through contract administration in addition to OSHA enforcement.

Documentation Requirements During Performance

Documentation ItemWhen RequiredPurpose
Written HCP document with professional supervisor identificationPrior to first noise-hazardous work / at contract awardConfirms HCP exists and 1910.95(g)(3) is satisfied before work begins
Baseline audiogram completion certificationBefore employees begin noise-hazardous workConfirms baselines established before exposure
Annual audiogram completion status reportAnnually during contract performanceDocuments annual testing compliance for enrolled employees
STS log with notification compliance documentationQuarterly or upon occurrenceDocuments STS identification and 21-day notification compliance
Training completion recordsAnnuallyDocuments annual 1910.95(k) training for enrolled employees

Contract Surveillance for HCP Compliance

  • Spot checks of posted HPD requirements in noise-hazardous work areas
  • Verification that employees in noise-hazardous areas are wearing appropriate HPDs
  • Review of submitted HCP documentation for completeness and currency
  • Random requests for audiometric records for specific enrolled employees to verify testing currency
  • Review of STS log and notification documentation upon occurrence

Subcontractor Flow-Down Requirements

  • Prime contractors must include HCP compliance requirements in subcontracts for noise-hazardous work
  • Prime contractors should verify subcontractor HCP documentation before subcontractor employees begin noise-hazardous work
  • Prime contractors should maintain documentation of subcontractor HCP compliance as part of contract file

Frequently Asked Questions

What HCP requirements should be in a government contract SOW?

At minimum: contractor responsibility for a 1910.95-compliant HCP; baseline audiograms before noise-hazardous work; independent record maintenance; records available for government audit within 5 business days; and professional supervisor identification. For DoD contracts, DoDI 6055.12 requirements may also be specified.

Can contracting officers require HCP compliance beyond OSHA minimums?

Yes. Contracting officers have authority to include safety requirements beyond OSHA minimums where there’s a legitimate program interest. For DoD contracts, requiring DoDI 6055.12 compliance is appropriate. Substantive SOW HCP requirements protect the government from contractor non-performance risk.

What FAR clauses are relevant to contractor hearing conservation compliance?

FAR 52.223-3 establishes baseline OSHA compliance obligations. FAR 52.236-13 applies to construction contracts. The most effective vehicle for substantive HCP requirements is a project-specific safety clause added under CO authority that explicitly enumerates 1910.95 elements as contract deliverables.

Should government contracts include audiometric testing documentation requirements?

Yes. Contracts should require contractors to maintain audiometric records, make them available to the COR within 5 business days of written request, and retain them per 1910.95(m). Requiring professional supervisor identification at contract start is particularly important — this is the most common and consequential HCP gap.
