- Finding type
- historical_record
- Finding
- NARA identifies ship-specific Navy correspondence, class-level machinery correspondence, shipyard correspondence, ship deck logs, and muster rolls as research avenues for investigating asbestos aboard a particular naval vessel. It cautions that class and yard records require hull-specific research and that vessels of the same class built at different yards may differ.

[7]Source review and search ledger for this record: archived NHHC DANFS Bethany entry; NARA ship-plan index, deck-log list, and asbestos research guide; GAO HRD-80-2 summary; CourtListener helper attempt (see search_ledger) [other_primary]
- Locator
- Search ledger rows sl-uss-bethany-pc620-01 through -09
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, material inventory, abatement record, or hazmat disclosure was located in the sources reviewed. This is a limited search result and does not show that asbestos was absent. The required CourtListener searches were not completed, so no litigation negative is reported.

- Limitations
- Absence of a located document is not evidence that asbestos was absent from the ship. NARA plan microfilm and deck logs were identified but not reviewed. CourtListener coverage is incomplete because the fleet pacing helper denied a token; litigation status is unresolved.
