The USS Casco (AVP-12), a United States Navy Barnegat-class small seaplane tender in commission from 1941 to 1947, was laid down on 30 May 1941 at Puget Sound Navy Yard in Bremerton, Washington. It was launched on 15 November 1941, sponsored by Mrs. W. J. Giles, and commissioned on 27 December 1941 with Commander Thomas S. Combs in command. After its decommissioning, the U.S. Navy loaned the USS Casco (AVP-12) to the United States Coast Guard, in which it served as the cutter USCGC Casco (WAVP-370), later WHEC-370, from 1949 to 1969. Because of the unique properties of asbestos, the following are the most common applications onboard ships: bulkhead and deck insulation (blankets, panels, and sprayed insulation); wall and ceiling panels (sandwich type); floating floors; floor tiles; cement, adhesive-like glue (e.g., mastics), and fillers; packing in pipe/cable penetrations; seals and sealing putty; gaskets (in pipe flanges). When asbestos fibers are inhaled, they become stuck in the lungs, which may lead to the formation of scar tissue. A buildup of scar tissue restricts airflow in and out of the lungs, making it difficult for the patient to breathe properly.
