    historical_record
    Finding
    HAER documents that Kaiser Cargo, Inc.'s Richmond Yard 4 was the Richmond LST yard: an 'almost skeletal workforce at Yard 4 merely assembled ship components fabricated by subcontractors throughout northern California,' the LST program there 'encountered serious problems at almost every turn' securing usable plans and Diesel powerplants, and the yard went on to become lead yard for the frigate program. NPS's Historic Richmond Shipyards page confirms the four Kaiser Richmond yards formed the largest shipbuilding complex in America.

    gov_survey
    Finding
    A U.S. Public Health Service industrial-health survey of pipe-covering operations during wartime Navy vessel construction: pipe covering on U.S. Navy vessels was amosite asbestos ('an important ingredient of pipe covering material used on U.S. Navy vessels is amosite'), with asbestos cloth and asbestos cement also in use; examinations and dust counts were run at two Government navy yards (A, B) and two Navy contract yards (C, D); of 1,074 pipe coverers X-rayed, three showed asbestosis, each with more than 20 years in the trade. The survey was triggered by an inspection of 'an important U.S. Navy Contract Yard' where pipe-covering dustiness was considerable and a few workers appeared to have asbestosis.

    Era-level documentation of wartime Navy-vessel construction, not a record for this hull: the four yards are anonymized (A-D) in the published paper, and no source consulted names Kaiser Richmond Yard 4 among them. It establishes that amosite pipe covering, asbestos cloth, and asbestos cement were standard aboard U.S. Navy vessels under construction in this period - which covers LST-485's build window - but does not prove their presence on this specific hull.

    Finding
    Documents the asbestos-supply regime in force during this hull's construction: the US classified asbestos as a critical material and began stockpiling in 1939; the first Asbestos Conservation order was issued 20 January 1942, essentially banning non-military use and giving priority to merchant and U.S./Royal Navy shipbuilding; regulations were tightened further in December 1942 - the month LST-485's keel was laid - and held until December 1944, with all orders revoked by 31 August 1945. The review also lists the Permanente yards at Richmond among the Pacific Coast emergency yards.
