[4]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 use and asbestos-insulation policy in Navy ships generally. The report does not identify USS LSM-264 or establish what material was installed aboard this hull.

- Population
- U.S. Navy ships and shipyard workers covered by the 1979 GAO review
- Limitations
- Direct access to GAO's product page and PDF returned 403 at final verification; the official search result supplied the report description and excerpt. This is Navy-wide policy and shipboard context, not hull-specific evidence. It does not establish any asbestos-containing product aboard LSM-264, quantity, location, condition, exposure, or causation.

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

- Beginning Research; General Information Books; Cartographic Branch (Ship Engineering Drawings)
- Finding type
- historical_record
- Finding
- NARA's asbestos research guide directs researchers to Bureau of Ships Record Group 19 correspondence, Amphibious Vessel General Information Books, and ship engineering drawings when investigating asbestos aboard a specific naval vessel. This identifies archival research paths; it is not an LSM-264 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-264 files were not requested or inspected; the guide itself states that the research process is complex and not comprehensive.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, product inventory, abatement record, condition report, or hazardous-material disclosure for LSM-264 was located in the public authoritative sources reviewed. Ship-specific asbestos documentation and asbestos presence aboard remain unknown.
