- Background, pp. 4-5 of PDF
- Finding type
- environmental_record
- Finding
- NIOSH's 1986 evaluation reports that Portsmouth Naval Shipyard's insulation shop had previously prepared and stored asbestos insulation, and that shop employees performed insulation rip-outs and pipe-covering work aboard Navy ships and submarines. The report says asbestos was not then being used as insulation in that shop.

- Limitations
- Occupational context at Portsmouth Naval Shipyard in the 1980s, not a hull, class, or construction-era record. It does not identify LSM-226, prove asbestos aboard it, or establish exposure for this ship's crew or workers, quantity, remaining material, or causation.

- This is a negative result only in the public Ship Plan Index, not a comprehensive search of NARA holdings or all Navy records. It does not establish that no ship plans, asbestos records, or other hull files exist, and it does not establish presence or absence of asbestos aboard.

- Hull-specific records
- Limitations
- A negative finding limited to accessible official sources checked. The NIOSH record is Navy yard context and not hull evidence; the NARA plan index is not a complete holdings search. Firecrawl was unavailable, the GAO product page was blocked, and non-digitized Navy engineering, maintenance, and yard files were not reviewed. Absence of a located record does not prove absence of asbestos aboard and does not establish exposure, causation, quantity, current condition, or legal eligibility.
