- Locator
- GAO product-page Highlights
- Finding type
- gov_survey
- Finding
- GAO's 1979 review of Navy efforts to protect workers from asbestos exposure states that it reviewed asbestos use in Navy ships and reports a 1975 Navy policy to remove and replace only damaged asbestos insulation or insulation removed for repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas.

[7]Inference from the ship-specific NavSource diesel specification, GAO Navy-wide asbestos-insulation context, and the documented source-review negative [other_primary]
- Locator
- NavSource propulsion/specification block; GAO HRD-80-2 product-page highlights; source-review negative in search ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-242 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.

- Possible categories only, not a finding that asbestos was installed aboard LSM-242. The cited hull page does not identify asbestos or insulation composition, and GAO does not name this hull; no quantity, location, condition, exposure, or causation is established.

- Finding type

- Finding
- The authenticated CourtListener API v4 exact-name opinion search for USS LSM-242 returned zero results. The remaining required exact-name docket and hull-number opinion/docket searches were not completed because the fleet-wide pacing limiter was saturated; no anonymous or non-helper request was made.

- The completed query is only one part of the required sweep and searches a text index; it is not proof that no qualifying case exists. The incomplete queries are an access gap, so this row does not classify the overall litigation sweep as a completed negative.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos documentation was located in the public sources reviewed: the NavSource hull page, official NHHC organization and photograph records, GAO program page, and completed CourtListener exact-name opinion search contain no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or qualifying asbestos litigation record for LSM-242.

- Limitations
- A negative public-source finding is not proof that asbestos was absent. CourtListener was incomplete and non-digitized Navy, shipyard, decommissioning, and scrapping records may contain additional evidence; asbestos documentation therefore remains class_or_era.

- Archival lead: NARA's Ship Plan Index identifies Record Group 19 as holding naval ship engineering-drawing series, including hull-series drawings, portfolio plans, microfilm, and aperture cards for numerous Navy vessels. A hull-specific LSM-242 drawing or work-package record was not located in the digitized index and would require further NARA catalog or research-room work.
