- Hingham shipyard workers; Navy crew; salvage and stripping workers
- Limitations
- DANFS documents identity, service, casualty, and disposition chronology only; it does not identify asbestos, insulation composition, product manufacturers, quantities, individual exposure, or present-day ACM. The cited URL is an archived copy; the live NHHC page was verified as unavailable at research time.

[3]NavSource Online, USS LST-921 hull page (live page verified 2026-10-03) [other_primary]
- Locator
- Hull page history lines and specifications/propulsion block
- Finding type
- historical_record
- Finding
- The hull page identifies LST-921 as a 542-class tank landing ship, gives the 1 May 1944 keel date, 2 June launch, 23 June commission, 14 August 1944 loss, 29 September decommissioning, 14 October striking, and NKAC call sign. Its specification block lists two General Motors 12-567A 900-hp diesel engines, one Falk main reduction gear, three diesel-drive 100-kW ship-service generators, two propellers, and 1,700 shp; it lists 7 officers/104 enlisted as complement and 16 officers/147 enlisted as troop accommodation.

- Population
- Ship crew and embarked troops; engineering and maintenance personnel
- Limitations
- NavSource is a secondary archival reference and its complement figure differs from some class-level compilations; the figure is retained only as a source-reported specification, not as a verified crew census. The machinery block establishes a diesel plant, not asbestos content or absence.

- Navy crew and shipboard operations during the indexed period
- Limitations
- The index establishes that records are listed and gives their date range; it does not disclose the deck-log contents, asbestos materials, maintenance, casualties, or exposure conditions. The deck logs were not retrieved or reviewed in this batch.

[5]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (published 1979; product page live but full report access was blocked to automated retrieval) [gao]
- Locator
- GAO product page Highlights
- Finding type
- gov_survey
- Finding
- GAO describes Navy asbestos use and the Navy's 1975 policy of replacing damaged or repair-disturbed insulation, modified in 1979 to include selective replacement in high-maintenance areas.

- Population
- Navy shipyard workers and Navy asbestos-management program
- Limitations
- Navy program and policy context, not a record about LST-921, its builder, or its materials. It does not establish that any asbestos-containing product was installed aboard this hull, does not quantify material, and does not establish exposure or present-day condition. Full report retrieval was blocked; the official product-page highlights were used.

[6]Batch-7464 public-source sweep: DANFS/NHHC, NARA, NavSource, GAO, and targeted web searches [other_primary]
- Locator
- Search ledger rows sl-uss-lst-921-lst921-01 through -08
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, material schedule, product-identification record, or museum/hulk hazmat disclosure was located for LST-921 in the sources searched. No ship-specific asbestos finding is therefore asserted.

- Limitations
- This is a bounded public-record search result, not proof that asbestos was absent. The vessel's 1944 Navy construction makes era-level material use a research possibility, but the hull-specific question remains unknown. NARA deck-log and Bureau of Ships construction/specification records were not fully retrieved.
