- Limitations
- DANFS entry is the mid-1960s volume text: it does not mention the 1960s recommissioning or Vietnam service documented by NavSource and NHHC photography, and gives no recommissioning date. Contains no asbestos, material, or industrial-hygiene information; establishes identity and timeline only.

Confirms the ship was in commissioned USS service under her county name in the western Pacific in 1967 - service the DANFS text does not describe.

- The 29 May 1963 recommissioning and 30 June 1967 decommissioning dates come only from this postal-history archive and conflict with the DANFS/NavSource transfer date of 15 April 1967; both variants are carried and the conflict is logged in gaps. Museum also labels the class "LST-511 Class," an error against DANFS/NavSource consensus (LST-491 class) - not propagated.

- Finding type
- regulatory
- Finding
- GAO documented Navy-wide use of asbestos insulation in ship construction and repair through the early 1970s - the program-level era context for a 1943-built amphibious hull. Combined with the class design record (LST-491 class: diesel plant, no boilers), the asbestos-relevant applications for the type are engine-room and exhaust lagging, machinery gaskets and valve packing, deck coverings, and accommodation insulation - era inference only.

- Finding type
- litigation_documented
- Finding
- A denied VA dependency-and-indemnity-compensation appeal alleged that a WWII deck-department sailor's multiple myeloma resulted from in-service exposure to chlorinated solvents incurred at Norfolk and "in the course of his duties on the USS Chase County, LST-532." The Board found solvent-exposure contentions credible and consistent with service conditions but denied the claim on nexus grounds. The veteran's DD 214 confirmed service on LST-532 in a general deck position (service September 1943 - February 1946).

- One veteran claimant (deck department, WWII)
- Limitations
- Classified OTHER LITIGATION, not qualifying asbestos litigation: the claim concerns chlorinated solvents, not asbestos, and is a benefits adjudication, not tort litigation. The decision anachronistically calls the ship "USS Chase County" for a 1943-1946 service period when she was USS LST-532 (named only in 1955). It contains no asbestos finding and no shipboard-conditions finding beyond the solvent discussion.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum documentation, or docketed asbestos case naming LST-532 / Chase County was found in the public sources searched (see search_ledger). The only adjudicated claim naming the hull is a non-asbestos VA solvent-exposure appeal (ev-06).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-built hull of the asbestos shipbuilding era transferred to Singapore and later merchant service leaves essentially no public paper trail. Does not establish that asbestos is or was present, nor any individual exposure or legal eligibility.
