[2]U.S. General Accounting Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct. 18, 1979) [gao]
- Locator
- Report pp. 1, 10-11 (Navy-wide applications and response); pp. 16-17 (ship list limited to vessels delivered since 1973 or under construction)
- Finding type
- gov_survey
- Finding
- GAO's 1979 review describes asbestos applications in Navy ships generally, including thermal insulation for machinery, equipment, and piping systems as well as other shipboard applications. The report does not identify USS LSM-248 or establish what material was installed aboard this hull.

- Population
- U.S. Navy ships and shipyard workers covered by the 1979 GAO review
- Limitations

[3]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]

- Beginning Research; RG 19 correspondence (lines 68-76); General Information Books, including Amphibious Vessel General Information Books (lines 263-305)
- Finding type
- historical_record
- Finding
- NARA's asbestos research guide directs researchers to Bureau of Ships Record Group 19 correspondence and ship information books when investigating asbestos aboard a specific naval vessel. This identifies an archival research path; it is not an LSM-248 record, and no hull-specific file was reviewed.

- Population
- Researchers examining U.S. naval-vessel asbestos records through 1961
- Limitations
- NARA's guide is not a vessel history or evidence of asbestos aboard this hull. Relevant LSM-248 and same-yard ship files were not requested or inspected; the guide itself cautions that the research process is complex and not comprehensive.

[4]Documented limited source-review negative; see search_ledger sl-uss-lsm-248-lsm248-01 through -06 [other_primary]
- Locator
- Limited public-source review of NHHC/DANFS, NARA, GAO, EPA, and NVR; Firecrawl search and scrape unavailable after quota response
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, condition report, or hazardous-material disclosure for LSM-248 was located in the public authoritative sources reviewed. Ship-specific asbestos documentation and asbestos presence aboard remain unknown.

- Limitations
- A limited public-source search negative is not proof asbestos was absent. Hull-specific Navy and shipyard files, surveys, transfer records, and disposal records were not reviewed. No product, quantity, location, condition, exposure, or causation is established.
