[4]NHHC, United States Naval Aviation 1910-1995, Appendix 12 'Ships Named for Naval Aviators' (entry: Hart - LT Patrick H. Hart, USN, commissioned 4 Nov 1944) [other_primary]

- Finding type
- historical_record
- Finding
- NHHC appendix confirms this hull's namesake and commissioning: 'Hart' listed among ships named for naval aviators as named for LT Patrick H. Hart, USN, with commissioning date 4 November 1944 - matching the DANFS commissioning date for DD-594. The first Hart (DD-110/DM-8, named for Ezekiel Bishop Hart and John E. Hart) was stricken 11 November 1931, freeing the name before DD-594's 21 March 1944 renaming from Mansfield.

[5]DANFS specifications block (Fletcher class; 2,050-ton destroyer) + Atlas shipyard dataset, Puget Sound Naval Shipyard record (DTIC AD0715808 Mangold/Beckett/Bessmer 1970; Environ Res 1976 PMID 1065583; 1940-1965 visual-historical review PMID 19235622) + NARA RG19 General Information Books archival lead [other_primary]

- asbestos_application
- Finding
- Era/yard inference: a WWII Fletcher-class destroyer with a four-boiler steam plant would have carried period-standard asbestos insulation, lagging, gaskets, packing, and fireproofing. The builder yard (Puget Sound Navy Yard, Bremerton) is documented at yard level in the Atlas dataset (tier 1): a peer-reviewed visual-historical review of PSNSY asbestos conditions circa 1940-1965 (overlapping this hull's 1943-44 construction) documents high airborne asbestos concentrations from raw fiber and insulation work; the 1970 yard study (DTIC AD0715808) and its 1976 follow-up (PMID 1065583) document amosite/chrysotile insulation products (preformed 85% magnesia block ~15% asbestos; asbestos cements; asbestos cloth) and fiber counts of 40-150 f/cc during rip-out. NARA RG19 'General Information Books' per-vessel material specifications are an archival lead for hull-level specs.

- Puget Sound Navy Yard construction trades 1943-44; crew 1944-46
- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding. Yard-level asbestos documentation at PSNSY is largely postwar (study period 1962-1972 for measurements; the visual review covers 1940-1965 as representative of era practice) and documents yard conditions, not materials aboard DD-594. PMID 19235622 co-authors include industry consultants (Paustenbach; Mangold, the original 1970 investigator) - noted in the yard dataset. NARA GIB retrieval not performed. Does not quantify material or establish any individual's exposure.

- Finding type
- gov_survey
- Finding
- Program-level era context: GAO documented that the Navy's major asbestos use aboard ships was thermal insulation, that substitution of alternative materials did not begin until the early 1970s - after this hull was already in the reserve fleet - that the October 1975 policy was remove-and-replace only when insulation was damaged or had to be removed for repairs, and that a one-time removal program was rejected on ~$2 billion estimated cost. Hart was stricken and sold for scrapping in 1973, before either removal policy existed.

- Finding type
- environmental_record
- Finding
- The site where this hull was broken up is a documented contaminated ship-breaking property: Oregon DEQ records the Portland South Waterfront site as an ironworks shipyard before WWII, purchased by Zidell in 1946, with 336 ships dismantled over ~30 years and scrap/waste used as site fill; contaminants include asbestos alongside metals, PCBs, PAHs, and petroleum; DEQ's 2005 Record of Decision drove upland capping/hot-spot removal, sediment work, and a certified asbestos-abatement project. EPA lists Zidell Explorations Inc. (ORD027765650) as NFRAP - assessed and not qualifying for the NPL.

- Limitations
- Documents the disposal SITE's contamination, not this hull: the source does not attribute asbestos to any specific vessel broken there, does not record this hull's breakup handling, and does not establish materials aboard DD-594. Retained as lifecycle context (the hull ended at a documented asbestos-contaminated scrapping site) - parallel to the Midway 'Building 11 is not the ship' discipline.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming DD-594 was found in the public sources searched (see search_ledger). CourtListener returned zero opinions and zero dockets for "USS Hart", zero opinions for "DD-594", and only name-collision dockets for "DD-594" (an in-document identifier match inside an unrelated employment case, Barbounis v. Middle East Forum, E.D. Pa.).
