- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. The entry text ends August 1974 and does not cover the December 1974 striking or the 1975 sale (see ev-02). Mirror transcription cited because the live NHHC page returns 404.

- Finding
- Secondary-compilation record for this hull's disposition: 'Stricken December 1 1974. Sold July 31 1975 to Boston Metals, Baltimore for $173,666 and broken up for scrap.' The same page repeats the DANFS build dates (laid down Bath Iron Works 7 December 1942; launched 24 April 1943; commissioned 29 June 1943) and gives machinery as 60,000 SHP General Electric geared turbines, 2 screws, crew 273. Consistent strike/sale figures appear in other secondary sources (globalsecurity.org DD-643 page; NavalCoverMuseum; Wikipedia).

- Limitations
- NavSource is a reputable volunteer secondary compilation, not a primary source; no primary disposal instrument was located (the Naval Vessel Register excludes pre-1987 disposals, and the DANFS entry ends August 1974). The $173,666 sale price is single-source (NavSource). The same page reads 'Decommissioned March 1 1947' against DANFS's 20 March 1946 - conflict carried in gaps rather than silently reconciled.

- asbestos_application
- Finding
- Era/yard inference: a WWII Fletcher-class destroyer built 1942-43 with a four-boiler/60,000-shp steam plant would have carried period-standard asbestos boiler and steam-line insulation, turbine lagging, gaskets, packing, fireproofing, and deck coverings; the builder yard (Bath Iron Works, Bath, ME) is documented at yard level in the Atlas dataset (tier 2), including a 1942 Harvard industrial-hygiene study by Dr. Philip Drinker recording a 'fairly serious dust risk' at ten times the safe threshold in the yard's pipe-covering shops - contemporaneous with this hull's construction.

- Bath Iron Works construction trades 1942-43; crew 1943-60
- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding. The 1942 Drinker study documents yard conditions during the period this hull was built but does not identify materials installed aboard DD-643; no hull-specific finding is made from it. Does not quantify material or establish any individual's exposure. NARA RG19 per-vessel General Information Books not retrieved (archival lead).

- GAO product page HRD-80-2
- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - placing DD-643's construction (1942-43) and entire commissioned service (1943-1960) inside the documented asbestos-use era.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located for DD-643: no hull ACM survey, abatement record, materials inventory, or hazmat disclosure exists in the sources searched, and no qualifying asbestos litigation names this hull - CourtListener opinion queries for 'USS Sigourney', 'Sigourney' + asbestos, and 'DD-643' returned zero hits; bare-name opinion hits are surname collisions (an 1841 chancery opinion and like-era reporters); and docket sweeps for 'Sigourney' (702 hits) and 'DD-643' (3 hits) resolve entirely to name collisions - bankruptcy and civil dockets for persons named Sigourney, street-address parties, and unrelated patent/employment document numbers - none naming this ship. The hull was stricken and sold for scrap in 1974-75 - before modern asbestos documentation practice - and never became a museum, so the disclosure channel that produced records for preserved hulls is absent.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 steam destroyer retained in reserve through 1974 is consistent with era-standard insulated fit, but that is class/era inference, not a ship-specific finding. Does not establish or defeat any claim of exposure or legal eligibility.
