   asbestos_application

   Finding

   A steel-hulled PC-461-class diesel submarine chaser built February-October 1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel patrol craft of this type and period were engine and exhaust lagging, machinery-space thermal insulation, gaskets, valve packing, electrical insulation, and fireproofing/deck coverings. As a twin-screw diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply. Her asbestos-relevant availability history includes a documented 1945 overhaul at Pearl Harbor and a 1959-60 reserve-fleet lay-up period.

The Atlas yard record also documents asbestos products at the yard (pipe covering, insulation blankets, amosite blankets, gaskets, asbestos mud/cloth) and asbestos contamination concentrated around Dry Dock 3 under EPA site HI6170024339.

    litigation_documented

    Finding

    Published Ninth Circuit opinion documenting asbestos exposure at this hull's builder yard: all parties stipulated that decedent James McAllister, a shipyard carpenter, died of mesothelioma caused by exposure to asbestos during maritime-situs employment for three Portland/Seattle shipyard employers, including Albina Engine & Machine, where he worked in 1956 doing work 'essentially identical' to his WISCO employment (WISCO admitted asbestos exposure at its yard). Procedural chain: the ALJ twice found Lockheed liable; the Benefits Review Board reversed and remanded twice (incl. BRB No. 04-0887, Aug. 19, 2005 - McAllister I, which remanded employment-specific exposure issues); on second remand ALJ Berlin found the evidence insufficient to show an absence of exposure at Albina and assigned liability to Albina as last responsible employer; the Board affirmed (Dec. 30, 2008); the Ninth Circuit granted review and, on burden-of-proof analysis, held Lockheed liable instead. Exposure at the Albina yard was treated as established in the record; the appellate disposition turned on burden allocation among employers, not on any finding that asbestos was absent at Albina.

    U.S. Navy crew recorded in deck logs

    Limitations

    The guide identifies log coverage, not log contents - the underlying logs were not retrieved and are not digitized. Coverage ends 31 December 1945; postwar logs (1946-1959) are not in this entry. Establishes nothing about asbestos, materials, exposure, or litigation - it marks where hull-level evidence would live.

    Finding

    No qualifying ship-specific asbestos record located for this hull: no asbestos survey, abatement contract, hazmat disclosure, material specification, or verified litigation naming PC-581 or Manville was found in the public sources searched. CourtListener status is PARTIAL: the 'USS Manville' opinion search (type=o, limit 20) completed and returned zero hits; the remaining three required base queries were still pending behind the fleet-wide request pacer at record time - logged as blocked in the search ledger, not as a negative result. Secondary web sweeps surfaced the yard-level Albina litigation (ev-10), the Jane's Indonesian-era listing (ev-06), and the NARA Special List 44 coverage entry (ev-12), and no qualifying hull case.

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - a 1942 naval vessel of this type sits inside the documented era of asbestos use in U.S. naval shipbuilding, and the hull served continuously through that era. The three unrun CourtListener base queries are a genuine open gap (blocked by pacing, not searched). NARA RG 24 deck logs (coverage listed to 1945 only), builder work packages, and the 1945 Pearl Harbor overhaul records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
