[4]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 Oct 1979), incl. Enclosure I Attachment 1 (Navy CNO Ser 4542/318054 of 5 Jan 1979) and Note 1 [gao]

- HRD-80-2 main text and Enclosure I Attachment 1 (TRIDENT SSBN block lists 726-730 only; hull 732 absent)
- Finding type
- gov_survey
- Finding
- Class/era federal record: GAO HRD-80-2 documents the Navy's asbestos-elimination policy - thermal-insulation product specifications changed to asbestos-free materials by late 1973; October 1975 policy (NAVSEAINST 5100.2) to remove/replace only damaged or work-required asbestos insulation, modified January 1979 to add selective replacement in high-maintenance areas; the Navy stated 'most ships delivered in the last several years or now under construction have little or no asbestos as thermal insulation,' while noting asbestos remained in applications lacking substitutes (gaskets, pipe hanger liners per Note 1; also brakes/clutches, deck tile, cabling, galley ranges per the letter text) - 'nearly impossible to build a Navy ship free of the mineral.' This hull (construction start 1983) is not among the hulls listed; the TRIDENT block covers 726-730 only.

- Limitations
- Class/era documentation only - this hull is not listed in Attachment 1 (construction began four years after the 1979 statement), so no ship-specific insulation designation exists for SSBN-732 in this source. Era context does not document materials aboard this hull.

- Finding type
- gov_survey
- Finding
- NIOSH Health Hazard Evaluation at Electric Boat Division, Groton (field visits July 1979-March 1981; report August 1983 - the year this hull was laid down): 'Historical reports of overexposure to asbestos were common among workers with eight or more years work experience at Electric Boat,' occurring 'primarily in the course of submarine overhaul and/or retrofit' performed at the Groton shipyard and a naval base in Spain; 'since the introduction of alternative forms of insulation for the reactor vessel and its complex of piping, asbestos use in the shipyard and on the submarines is slowly being phased out.' The report identifies the Trident class as one of the two submarine types manufactured at Electric Boat.

- Litigation sweep result: exact-name and hull-number searches ('USS Alaska' / 'Alaska' + 'SSBN-732') across CourtListener/indexed RECAP documents and the five retrieved N.D. Cal. asbestos complaint exhibits (Halseth, Cooks, Davis, Cronin, McIntyre rosters) produced no qualifying asbestos litigation naming this hull. 'Alaska' is a high-collision name - returned hits were unrelated litigation, military matters, name collisions, or non-asbestos documents.
