- WWII crew (13 officers, 104 enlisted per ONI-1945 figures via NavSource); embarked troops
- Limitations
- DANFS is silent on the ship's fate after striking and gives a commissioning commanding officer (Lt. W. R. Evans) that conflicts with NavSource's CO list (LT Addison R. Brown, USNR, 16 November 1944) - see gaps. Contains no asbestos, material, or insulation information of any kind.

- Population
- WWII crew; embarked Marines (occupation lifts, 1945)
- Limitations
- NavSource is a volunteer-maintained archival compilation, not a government publication. Its final-disposition line (transfer to Occupation authorities for use by Japan) is not corroborated by DANFS and the ship's fate after 1946 is undocumented in sources searched; the Kagoshima grounding detail derives from contributor photo captions. CO list conflicts with DANFS on the commissioning commanding officer - see gaps. Contains no asbestos, material, or insulation information.

[4]U.S. GAO, HRD-80-2, 'Navy Efforts To Protect Workers From Asbestos Exposure' (1979) - product page via Wayback Machine capture 2025-04-02 (archived copy; live gao.gov returns HTTP 403 to automated fetches) [gao]

- GAO product page, report abstract (Wayback capture 2025-04-02)
- Finding type
- historical_record
- Finding
- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards - government documentation that asbestos exposure was a recognized, systemic occupational hazard in the Navy ship construction and overhaul system of the era that built and maintained this hull.

- Study period
- 1979 (report); WWII-through-1970s exposure era
- Population
- Navy shipyard workers (class context)
- Limitations
- Program- and yard-level document: it does not name this hull, any LST, or the Evansville builder yard, and its fieldwork yards were Long Beach and Norfolk. Establishes era/system context only - it is not evidence of asbestos aboard LST-820 and establishes no quantity, product, or individual exposure. Full text not pulled; row rests on the GAO product-page description (archived capture), so verification is partial.

- search_ledger rows sl-uss-lst-820-01 through sl-uss-lst-820-08
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming LST-820 was found in the public sources searched (see search_ledger). CourtListener could not be searched this session - the fleet-shared daily API quota was exhausted at research time (helper-reported wait ~6.7 h) - so litigation status is OPEN, not negative; secondary web sweeps surfaced no qualifying case naming this hull, only law-firm marketing content (excluded source class).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - WWII-era construction is consistent with retained era materials, but no hull-specific documentation confirms or excludes asbestos presence. The unsearched CourtListener index means a docketed case could exist undetected; this row must be re-run when quota resets. Does not establish or defeat any claim of exposure or legal eligibility.
