The OSHA requirement to retain audiometric records for employment duration plus 30 years creates a records management obligation that outlasts most HR systems, vendor relationships, and organizational structures. For terminated employees, this means audiometric records from a worker who left in 2000 must remain accessible through 2030. For long-tenured employees who retired in 2010 after 35 years of employment, records from their hire in 1975 must remain accessible through 2040. OSHA 29 CFR 1910.95(m) and 29 CFR 1910.20 establish these retention requirements. According to CDC/NIOSH, approximately 22 million U.S. workers face hazardous noise annually, and the audiometric records generated for each worker represent an ongoing retention obligation.
The Retention Requirement in Practice
The 30-year post-employment retention period means:
- A worker hired in 2020 and terminated in 2025 — records must be retained until 2055
- A worker hired in 1990 and retired in 2025 after 35 years — records from 1990 must be retained until 2055
- A worker hired in 2000 and terminated for cause in 2005 — records must be retained until 2035
This retention horizon far exceeds the life of most software platforms, HR systems, and vendor relationships. Employers who store records in incumbent EHR or occupational health software systems will likely need to migrate records multiple times during the required retention period.
Corporate acquisitions, mergers, and divestitures create significant audiometric records risk. The acquiring company may not receive legacy audiometric records as part of the transaction, leaving a gap in the record set for workers who transfer employment. The divesting company may destroy records believing they were transferred when they were not. OSHA 29 CFR 1910.20 requires records transfer to successors or notification to NIOSH — but in practice, records are frequently lost in M&A transactions.
Transfer Obligations at Business Cessation
When an employer ceases to do business, 29 CFR 1910.20 requires that employee exposure and medical records (including audiometric records) be transferred to the successor employer or, if there is no successor, that NIOSH and affected employees are notified at least 3 months before disposal so they can request the records. Bankruptcy and liquidation situations create special challenges, and records should be addressed as a specific issue in restructuring proceedings.
When acquiring a business with noise-exposed workers, include audiometric records in due diligence: (1) confirm the target has a compliant HCP, (2) request the complete audiometric record set for current employees, (3) confirm records are in an accessible, transferable format, (4) identify the record retention system and confirm it will be transferred or migrated, (5) address former employees’ records that must be retained post-closing.
