- search_ledger rows sl-uss-lev-iii-yp157-01 through sl-uss-lev-iii-yp157-08
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched: no asbestos survey, abatement contract, hazmat disclosure, material specification, or ship-specific asbestos litigation record naming Lev III or YP-157 was found. The canonical identity is retained once in this record because the NavSource page identifies the former name and hull number as the same vessel.

- A negative public-source search does not prove absence of asbestos aboard. It establishes only that no qualifying public record was located; it does not establish exposure, causation, legal eligibility, or present-day material condition.

- Finding type
- asbestos_application
- Finding
- The National Archives guide for researching asbestos aboard U.S. naval vessels identifies ship engineering drawings and related records as relevant avenues, including S39 insulation and lagging and S48 piping, and explains that ship-specific archival research is needed. This is research-path and Navy-era context only; it does not document asbestos aboard YP-157.
