- Nevins construction trades (1942); Navy crew during service
- Limitations
- NavSource is a secondary compilation and photograph archive, not the underlying Navy registry or service record; its page supplies the located hull-level milestones and specifications but contains no asbestos content, service diary, commissioning date, or decommissioning date.

- YMS-8 crew and ship operations documented by the inventoried logs
- Limitations
- This is an inventory entry, not the contents of the logs. The dates are log-coverage bounds and are not asserted as commissioning or decommissioning dates. The logs were not examined for asbestos, maintenance, or exposure information; public online-log availability was checked and YMS-8 was not located in the available catalog list.

- Locator
- YMS/BYMS index class-history paragraph and general-characteristics block
- Finding type
- historical_record
- Finding
- The YMS index describes the type as wood-hulled and gives the general YMS machinery context as General Motors 8-268A diesel engines and two shafts; it describes the YMS program as a large group of yard-built minesweepers used for minesweeping and related Navy work.

[5]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) [gao]
- Locator
- GAO HRD-80-2 product page; full-text access gap recorded in report
- Finding type
- gov_survey
- Finding
- GAO's Navy program review documents extensive Navy use of asbestos insulation aboard ships and later substitution of alternative insulation materials beginning in the early 1970s; this provides era context for a hull built in 1942 and operated during the WWII period.

- Limitations
- Program-level evidence only; it does not name YMS-8, identify a product aboard this hull, establish remaining material, disturbance, dose, or individual exposure. The GAO full-text document was not retrieved because the product page was accessible but automated full-text access was blocked.

[6]Authenticated CourtListener four-query base sweep attempted through cl-auth-search.py [court_record]

- Finding type
- historical_record
- Finding
- No CourtListener result classification is made: the first exact-name opinion request entered the fleet-wide authenticated pacing queue and reported a multi-hour wait before a result was returned. The remaining three required base queries were stopped; no asbestos-qualified variants were run.

- Limitations
- This is an incomplete sweep, not a no-litigation finding. The four required queries were attempted only through the authenticated helper; because the limiter indicated a multi-hour wait, CourtListener work was stopped as instructed. No opinion or docket hit was read or classified.

- Search ledger rows sl-uss-yms-8-01 through sl-uss-yms-8-07
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos survey, abatement record, hazmat disclosure, product identification, material schedule, or adjudicated exposure finding naming USS YMS-8 was located in the authoritative and archival sources searched. Ship-specific asbestos status is unknown.

- Limitations
- A negative public-source result does not prove absence of asbestos aboard. The NARA deck logs are an undigitized archival lead, and engineering specifications, ship information books, work packages, disposal records, and any litigation outside the incomplete CourtListener sweep remain open. No class or era evidence is upgraded to a hull-specific finding.
