[4]U.S. General Accounting Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) [gao]

- Finding type
- gov_survey
- Finding
- GAO's HRD-80-2 describes Navy-wide asbestos applications including thermal insulation for machinery, equipment, and piping systems; Navy ship decks; piping gaskets and packing; and equipment brakes and clutches, in a review covering Long Beach and Norfolk Naval Shipyards. The report does not identify USS LSM-280 or establish that any listed material was installed aboard this hull.

- Limitations
- Navy-wide context from a program review centered on two shipyards neither of which built or is documented to have serviced LSM-280. It does not establish any asbestos-containing product aboard LSM-280, quantity, location, condition, exposure, or causation.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, condition report, hazmat disclosure, or disposal record for LSM-280 was located in the bounded authoritative-source review. Ship-specific asbestos documentation and asbestos presence aboard remain unknown.

- Limitations
- A bounded public-source negative is not proof asbestos was absent. Non-digitized Navy, shipyard, inspection, maintenance, and disposal records were not reviewed; no product, quantity, location, condition, exposure, or causation is established. The CourtListener sweep is incomplete (one of four required queries blocked by fleet pacing; see gaps).

- Finding
- NARA's research guide identifies Bureau of Ships Record Group 19 correspondence, amphibious-vessel General Information Books, ship engineering drawings (series S39, Insulation and Lagging), and Record Group 38 amphibious-vessel inspection reports as research paths for vessel-specific asbestos investigation. No LSM-280 file from those series was requested or inspected.

- Finding type
- litigation_documented
- Finding
- No qualifying asbestos opinion or docket naming this hull by exact name ('USS LSM-280') or hull number ('LSM-280') was located in any of the four required CourtListener sweeps (exact-name opinion, hull-number opinion, exact-name docket, hull-number docket), each returning zero results.

- All four completed queries found no indexed opinion or docket naming this hull; this does not establish that no litigation exists, only that none was found in CourtListener's indexed collections for the completed query set. No claim of litigation status, exposure, or eligibility is made from this row.

- Finding
- The live hull page reports that LSM-280 was laid down 8 September 1944 at Federal Shipbuilding and Dry Dock Co., Newark, New Jersey; launched 21 October 1944; and commissioned as USS LSM-280 on 6 November 1944 with LTjg. Edward S. Hand, USNR, in command.

- Federal Shipbuilding construction workforce and commissioning crew
- Limitations
- The live page supports the reported construction and commissioning chronology but is not a Navy DANFS page, and no second source was found to independently corroborate it. It does not identify asbestos, insulation composition, exposure, or causation. The builder-location label 'Newark, N.J.' carries an unresolved Kearny-vs-Port Newark ambiguity (see gaps).
