[2]U.S. General Accounting Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct. 18, 1979), p. 3 [gao]

- GAO HRD-80-2, enclosure I, Navy letter dated Jan. 5, 1979, PDF pp. 10–11
- Finding type
- asbestos_application
- Finding
- A Navy letter enclosed in GAO HRD-80-2 states that ships on its list of vessels delivered since 1973 or under construction had several types of asbestos-containing materials installed. The Navy identified thermal insulation for machinery, equipment, and piping systems as the major shipboard application.

- Study period
- 1979 report; general shipboard practice
- Population
- Navy ships delivered since 1973 or under construction, as described in the Navy letter; not this identified hull
- Limitations
- General Navy context only; the listed population is later-delivered or under-construction vessels, and the report does not identify or inspect Clarion River. This does not establish that any asbestos-containing material was aboard this 1945 hull, or its quantity, location, condition, or persistence.

[4]GAO HRD-80-2 live product page; documented research coverage and negative finding [other_primary]
- Locator
- Search ledger queries and access notes in this record; GAO product page identifies its fieldwork scope
- Finding type
- abatement_record
- Finding
- No public ship-specific asbestos survey, abatement record, or hazardous-material disclosure for USS Clarion River/LSMR-409 was verified in the sources accessible for this batch. A complete litigation sweep was not possible. The GAO review located is program-level and covers Long Beach and Norfolk Naval Shipyards, not this hull.

- Population
- Publicly accessible records searched for this hull
- Limitations
- This is a bounded search result, not proof that no such records exist. Firecrawl was unavailable because its keyless MCP quota was exhausted; CourtListener authenticated searches for the exact name and hull number were blocked by the fleet pacing limiter. No no-result conclusion is drawn for litigation. See search_ledger and report.
