- asbestos_application
- Finding
- A diesel-powered PC-461-class submarine chaser built 1943-44 at a Navy contract yard sits inside the documented WWII naval-construction asbestos era: the 1946 Fleischer/Drinker survey of Navy and contract yards documents amosite pipe covering, asbestos cloth, and asbestos cement as standard pipe-covering materials in naval vessel construction, and GAO documents Navy-wide asbestos insulation use into the early 1970s. Era-standard applications aboard a small diesel combatant of this period were thermal insulation, diesel-engine and exhaust-system lagging, gaskets and valve packing throughout machinery spaces, electrical insulation and cable, deck coverings, accommodation-space insulation, brake linings, and fireproofing. The hull carries no boilers or steam plant - the boiler/turbine lagging pathway does not apply. Her own war diaries document repeated work on the diesel plant that is the era-relevant disturbance pathway: a ten-day 'complete inspection of main engines' availability (May 1945, Pearl Harbor Navy Yard), a three-day tender availability alongside USS ZEUS (June 1945), five days for 'repair of main engine mufflers' (August 1945, Eniwetok), and a further availability 'for replacing main engine mufflers' (August 1945, Pearl Harbor) - maintenance on the exhaust/muffler system where era lagging would have been applied.

The pipe covering 'frequently employed was amosite' (a magnesium-iron silicate asbestos), and 'much asbestos cloth and asbestos cement were likewise used.' Documents that amosite insulation materials were standard in naval-vessel construction during the period this hull was built at a Navy contract yard.

The MARAD Vessel History Database contains no record for this hull. Secondary web sweeps surfaced no qualifying litigation and no ship-specific asbestos material; the only 'asbestos' content encountered for PC-class hulls generally is law-firm listicle content excluded by source policy.
