How to Recover Audiometric Records From a Previous Testing Vendor or Mobile Van Provider

When audiometric testing runs through a vendor — a mobile van provider, an occupational health clinic, a testing service — the records that program generates frequently live only in the vendor’s system. That arrangement works until the relationship ends. Under OSHA 29 CFR 1910.95(m), the retention and access obligations belong to the employer, not the vendor: audiometric records must be kept for the duration of each worker’s employment, and employees and former employees are entitled to them within 15 working days of a request under 1910.95(m)(4) and 29 CFR 1910.1020. If a former vendor holds your only copy, you are one purge cycle, acquisition, or unreturned email away from a recordkeeping gap you did not create but will own. This guide is the recovery playbook.

Records Ownership: Whose Data Is It?

Start from the regulatory reality: OSHA’s recordkeeping obligations attach to the employer. If a compliance officer asks for a worker’s baseline and annual series, “our former vendor has it” is not a defense — the citation lands on you. If a former employee’s attorney requests records under 1910.1020, the 15-working-day clock runs against you, not the vendor. The plain-language 1910.95(m) guide covers the underlying requirements in detail.

Service contracts vary in what they say about data return, retention after termination, and export fees — and some say nothing at all. Read yours before making the request so you know whether you are invoking a contractual right or asking a favor. Either way, the practical position is the same: these are records of your employees’ occupational health surveillance, generated under your program, to satisfy your regulatory obligations. Reputable vendors treat them accordingly. Record portability is also one of the first things to evaluate in any new vendor relationship — a point made forcefully in Thinking of Changing Your Audiometric Testing Vendor in 2026?

What to Request, Item by Item

The most common recovery failure is under-asking. A vendor asked for “our records” will often send recent summary reports and consider the job done. Request the complete set, by name:

• Every baseline audiogram for every worker ever tested under your account — including workers who have since left. Former-employee records are the ones hearing loss claims reach for decades later.
• Every annual audiogram and retest, with per-frequency thresholds in dB HL for each ear — not just pass/fail or STS-flag summaries.
• Baseline revision history: which test is the operative baseline for each worker, when any revision occurred, and the professional determination behind it.
• STS determinations and reviews: shift calculations, age-correction applications, professional supervisor findings, and work-relatedness assessments.
• Test conditions data: audiometer calibration dates and ambient booth levels — required record content under 1910.95(m)(2).
• Employee notification records: documentation of the written STS notifications the standard requires.
• Any noise monitoring data the vendor collected under your program, per 1910.95(m)(3).

Also ask the vendor to state, in writing, whether the export is complete — and if any records were purged, which ones and when. A completeness statement turns an export into an auditable event.

Export Formats: Structured Data Plus Source PDFs

Format determines whether the recovered records are usable or merely archived. Insist on both halves:

• Structured data — CSV, spreadsheet, or database export with one row per test: employee identifier, test date, test type, examiner, calibration date, and thresholds per frequency per ear. This is what makes future STS comparison, per-employee indexing, and program analytics possible.
• Original report PDFs — the signed, formatted documents as evidentiary source records, linked to the structured rows they correspond to.

A PDF-only export is half a recovery: the tests are preserved as pictures, but every threshold still has to be extracted before the data can do anything. Why that matters — and how to convert a PDF archive you are stuck with — is the subject of Scanned PDF Audiograms vs. Structured Data.

How to Make the Request

Treat the request as a compliance action, not an errand:

• In writing, to a named contact, with your account details, facility names, and the date range of the testing relationship.
• Enumerate the record categories from the list above and specify the formats — structured export plus PDFs.
• Cite the basis: your retention and access obligations under 1910.95(m) and 1910.1020, and any contractual data-return clause.
• Set a reasonable deadline (two to four weeks is common), ask for confirmation of receipt, and ask up front about any export fee so it cannot become a later stall.
• Keep every exchange: the correspondence trail is itself a compliance record — if recovery ultimately fails, it documents the good-faith effort.

The best time to export your records was before the contract ended. The second-best time is today, in writing, with the complete list attached.

Slow, Defunct, or Unresponsive Vendors

When the polite request stalls, escalate in stages:

• Follow up on a schedule, in writing, referencing the prior request and deadline. Move from your operational contact to the vendor’s management or compliance function.
• Invoke the contract: if a data-return or records clause exists, cite it specifically; involve procurement or counsel for a formal demand letter if needed.
• Trace acquisitions: testing providers consolidate frequently. If the vendor was acquired or dissolved, the successor company or the supervising audiologist of record may hold the archive. OSHA’s transfer provision at 1910.95(m)(5) contemplates exactly this kind of succession for employers, and reputable successors understand the principle.
• Ask affected workers: employees sometimes retained their own copies of results — a legitimate partial source worth collecting while the formal channel grinds on.
• If recovery fails, document and remediate: close the file with the full correspondence trail, then handle the resulting gaps — especially missing baselines — through the documented investigation and re-establishment process in Lost or Missing Baseline Audiograms.

What to Do With the Records Once You Have Them

A recovered export is raw material, not a finished archive. Three steps make it usable:

• Validate: check completeness against the request list, confirm thresholds and dates are plausible, and reconcile the worker list against your roster — including former employees.
• Index by employee: assemble each worker’s series — baseline, revisions, annuals in order — and merge the vendor data with whatever paper, PDF, or spreadsheet history you already hold, flagging duplicates rather than double-counting them.
• Land it in managed custody: a structured, backed-up, employee-indexed system with retention controls, so the next vendor transition is a non-event.

The end-to-end method — gathering, conversion, validation, and per-employee indexing across all your sources at once — is covered in the complete guide to digitizing historical audiogram records by employee. And if you would rather not run the project internally: Soundtrace’s historical records audit accepts vendor exports in any format alongside your paper and PDFs, and digitizes, validates, and loads everything per employee at no cost, no contract required.
