- Finding type
- asbestos_application
- Finding
- A peer-reviewed historical study documents asbestos use as fireproofing and insulation in World War II U.S. shipbuilding. For LSM-181, that supports only class/era context: possible applications include machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck or fireproofing materials; the study does not name LSM-181 or establish that any listed material was installed aboard this hull.

[7]Source-review negative across NARA RG 181 and the live NavSource LSM-181 hull page; Firecrawl access gap recorded in search ledger [other_primary]
- Locator
- Search-ledger rows sl-uss-lsm-181-lsm181-01 through -07
- Finding type
- historical_record
- Finding
- The public source review located no ship-specific asbestos survey, product inventory, abatement record, hazmat disclosure, or condition report for USS LSM-181. The located NARA finding aid and NavSource hull page document identity, construction, specifications, service/disposition, and commissioning records but do not document asbestos or insulation composition.

- Limitations
- A negative public-source finding is not proof that asbestos was absent. The undigitized commissioning file, non-public Navy records, conversion records, and unsearched litigation results may contain additional evidence; asbestos documentation remains class_or_era.
