- Limitations
- The finding aid confirms the file-series entry and its listed date, not the contents of the file. The table does not label the date's event; this record does not treat it as a commissioning date. It does not establish asbestos materials, quantities, condition, exposure, causation, or legal eligibility.

- Finding type
- asbestos_application
- Finding
- No qualifying ship-specific asbestos record located: the accessible public sources searched for LSM-186 located no asbestos survey, product inventory, abatement contract, hazmat disclosure, or ship-specific exposure record. Asbestos aboard this hull remains unknown.

- Study period
- 1944-2026
- Population
- Construction workers, ship's company, and disposal workers
- Limitations
- This is a negative public-source finding, not proof that asbestos was absent. Firecrawl was quota-blocked, and CourtListener pacing stopped the required litigation sweep before a response; those are disclosed gaps. The finding does not establish or defeat exposure, causation, or legal eligibility.
