- asbestos_application
- Finding
- Construction by Kaiser at Vancouver, Wash., under a Maritime Commission contract (type S4-S2-BB3) inside the Navy's peak asbestos-insulation era, plus this hull's documented maintenance events - San Diego repairs from 15 February 1945 (facility unnamed); inactivation at Boston 1946 (Boston Naval Shipyard inference - flagged) - are the ship-specific exposure-relevant facts. Asbestos applications standard to this steam plant's era and class: boiler and steam-drum insulation, magnesia and amosite pipe covering, asbestos felt, cloth/tape lagging, millboard, insulating and finishing cements, valve and flange gaskets, and machinery packing. The documented repair/overhaul events are the maintenance-disturbance pathways on this hull.

[4]U.S. Navy, Bureau of Ships Technical Manual, NAVSHIPS 250-000, Chapter 39 'Thermal Insulation' (1960, page date 15 April 1959) - specification-level document for Navy shipboard insulation materials [other_primary]

- Finding type
- asbestos_application
- Finding
- The 1960 BuShips Technical Manual's insulation chapter enumerates the asbestos material suite standard to Navy steam plants of this class's construction era: MIL-P-2781 pipe covering including 85% magnesia 'formed from a combination of 85 percent magnesium carbonate with about 15 percent asbestos fiber' and a class 'formed from a uniform mixture of amosite asbestos fibers'; roll asbestos felt MIL-I-15091; asbestos cloth/tape SS-C-466 (80-95% chrysotile) as lagging; asbestos millboard HH-M-351; asbestos finishing cement; molded asbestos block for high-temperature service. This hull's four B&W boilers, Skinner reciprocating engines, and steam piping are the equipment classes these specifications cover.

- Opinion factual background (Navy equipment asbestos use; PSNS exposure history)
- Finding type
- litigation_documented
- Finding
- Washington Supreme Court's factual summary states that Navy specifications called for asbestos-containing insulation, gaskets, and packing aboard its vessels: 'the use of asbestos in and on Navy valves, pumps, and turbines was not by chance, but by design.' The opinion describes pipefitters/insulators disturbing asbestos insulation during shipyard maintenance at Puget Sound Naval Shipyard - the same Pacific Northwest naval-shipyard ecosystem this hull moved through.

- Finding
- Washington State Dept. of Ecology cleanup-site record for the 'Kaiser Shipyard Debris Pile': in 1942 the site was developed as part of the Kaiser Vancouver Shipyard, which 'was responsible for construction of liberty ships, escort carriers, and transport ships used during World War II'; shipyard debris (metal, pipes, firebrick, ceramics) was used as fill 1940-1946. This is the official environmental record of the yard that built this hull.
