   DANFS record for this hull (spec line: 'AM-423: dp. 620; l. 172'; b. 36'; dr. 10'; s. 15 k.; cpl. 74; a. 1 40mm.; cl.

   Limitations

   DANFS documents service history, dates, and specifications - it contains no asbestos, insulation-material, or industrial-hygiene information for this hull. It documents where the hull was (construction and five yard periods) but says nothing about what was aboard. Yard periods listed are documented events; their asbestos scope is undocumented.

   Secondary compilation corroborating DANFS: 'Aggressive Class Ocean Minesweeper'; laid down 1951-08-01 Luders Marine Construction Co., Stamford, Conn.; launched 1953-03-15; commissioned 1954-05-13; reclassified MSO-423 1955-01-14; heavily damaged by fire of unknown origin at Bethlehem Steel Corp., Fort McHenry Shipyard, Baltimore, on 1969-10-06; decommissioned 1970-01-31; struck 1970-02-01. Specifications: displacement 630 lt / 755 fl tons; length 172 ft; beam 35 ft; draft 10 ft; speed 14 kts; complement 80; armament one 40mm mount and two .50 cal. machine guns; propulsion four Packard ID1700 diesel engines, two shafts, two controllable-pitch propellers. Sale entry: 'Sold for scrap 6 October 1969 to Steve B. Clemons of Miami Shores, FL for $2,789' - a date identical to the fire and months before striking; carried in gaps.

   Limitations

   Volunteer-compiled secondary archive, not an official record; key dates corroborate DANFS verbatim. Complement (80) conflicts with the DANFS spec line (74). Propulsion detail (Packard diesels) is consistent with the class design but not separately verified against a primary document. The scrap-sale date is internally inconsistent (same day as the fire, pre-striking) and treated as a transcription error. No asbestos information.

   Finding type

   asbestos_application

   Finding

   Class/era inference: this hull is a 1950s SCB-45A-design ocean minesweeper (Aggressive class, often cataloged Agile) - 'smaller and built primarily of wood, with bronze and stainless (non-magnetic) steel fittings to minimize their magnetic signature' (NavSource class index), diesel-powered with four Packard engines. A Navy vessel built 1951-53 and overhauled through 1969 falls inside the era when asbestos was standard marine material. Era-typical applications aboard a diesel minesweeper would include engine exhaust lagging, machinery-space insulation, gaskets, packing, electrical insulation, deck coverings, joiner/fireproofing materials, and brake/clutch linings on sweep-deck winch machinery. No located document names these materials aboard this hull.

   Population

   Construction trades (Stamford, 1951-53); crew 1954-69; yard workers at five documented repair/overhaul periods

   Limitations

   Inference only, not a ship-specific finding: no hull-level material specification, survey, or abatement record was located. The wooden hull and diesel plant imply a smaller asbestos envelope than steam combatants (no boiler or steam-line insulation), but 'smaller' is not 'absent' - electrical, gasket, and machinery applications remained asbestos-standard through the 1960s. Does not establish quantity, friability, or present-day (pre-loss) presence.

   Finding

   Identifies the yard complex where this hull spent its final 13 months and burned: Bethlehem Steel's 'Baltimore yards' were two separate repair yards - the Key Highway yard (upper yard, near the Inner Harbor) and the Fort McHenry yard (lower yard, Locust Point peninsula, adjoining the 1879 graving dock) - distinct from the Sparrows Point construction yard; at their peak the two yards employed about 1,700 craftspeople and repaired an average of 500 ships per year; Bethlehem closed them at the end of 1982.

   Peer-reviewed epidemiology establishing the ship-repair exposure pathway for vessels of this era: 'significant amounts [of asbestos] were used in vessels constructed before 1975' and repair of such vessels carried continuing exposure potential; of 286 ship-repair workers 30 or more years from employment onset, 86% had radiological evidence of asbestosis.

   Population-level evidence about ship repair generally - the abstract does not name this hull, the Bethlehem Baltimore yards, or any specific facility; the Atlas shipyards.json record characterizes the studied workforce as Bethlehem Steel's Baltimore shipyard workers, but the paper's abstract alone does not establish that link. Establishes pathway plausibility for the documented 1968-69 repair/modernization period, not asbestos presence aboard this hull.

   Absence of a located public record does not prove absence of asbestos aboard - era-consistent materials likely existed and the hull was destroyed by fire and scrapped without any documented hazmat process. This row does not establish that asbestos is or is not present, and does not establish or defeat any claim of exposure or legal eligibility.
