[3]Research search result documented in this record's search ledger; the search did not locate a ship-specific asbestos survey, abatement record, or material inventory [other_primary]

- See search ledger rows 01, 02, and 04 and the limitations note for the sources searched and access limits
- Finding type
- historical_record
- Finding
- Within the official sources searched for this record, no ship-specific asbestos survey, abatement record, or material inventory for PC-493 was located. This is a search result, not evidence that asbestos was absent.

- Limitations
- This negative finding is limited to the sources and access available in this session. The NARA list is a deck-log inventory, not an asbestos record; Firecrawl was quota-blocked and CourtListener research was cut short by the shared pacing limiter. Absence of a located record does not establish absence of asbestos or exposure.
