- historical_record
- Finding
- NARA inventories deck logs for this hull: 'YMS-391 9/24/1943 5/17/1946' - logbooks exist in Record Group 24 holdings at the National Archives covering 24 September 1943 through 17 May 1946. YMS-391 does not appear in the NARA list of deck logs digitized online in the National Archives Catalog, so the logs are physical-holdings material at College Park.

- Finding
- A named crew member is documented aboard this hull: the Veterans History Project service summary for Charles A. Dasey (Gunner's Mate Second Class, U.S. Navy, enlisted, WWII) lists 'USS YMS-391 (Yard Minesweeper)' among his service units alongside USS LST-344 and USS LST-1066. His aggregate service history covers the European Theater - Gela, Sicily, Salerno, and Omaha Beach - and campaigns including Torch, Husky, and Overlord.

- Crew member (Gunner's Mate Second Class) - service aboard this hull within the WWII window
- Limitations
- The VHP summary is veteran-level: it lists ships and campaigns in aggregate and does NOT allocate specific campaigns or locations to specific ships - it does not establish that YMS-391 was at any of the named actions. YMS-391 was not completed until 19 September 1943, after Torch (Nov 1942) and the Husky assault phase (July 1943). This is a service record, not an exposure record; contains no asbestos content.

[6]YMS-1 class configuration per NavSource specifications for this hull (diesel plant, wooden-hull type per class literature); corroborating yard-list displacement figures per shipbuildinghistory.com YMS list [other_primary]

- Finding type
- asbestos_application
- Finding
- Era inference for asbestos applications aboard a WWII YMS-1 class hull: the class was wooden-hulled with a twin GM diesel plant and no boilers or steam system, eliminating the boiler/turbine lagging and steam-line insulation pathways dominant on steam vessels. Era-standard applications that could still have applied aboard a craft of this type and period: machinery and exhaust gaskets, valve packing, electrical insulation, and limited interior fireproofing/housekeeping materials.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, or work package located for YMS-391. Names era-standard possibilities, not confirmed installed materials. No quantity. Diesel wooden-hulled craft carried materially less asbestos-relevant plant than contemporary steel steamships; inference should not be read as ship-proven.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]
- Locator
- GAO product page HRD-80-2, Highlights section
- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards, specifically covering 'the use of asbestos in Navy ships.' The product page states the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas - documenting that asbestos insulation remained installed aboard Navy ships through at least the late 1970s, and that this hull's 1943-47 service era predates the Navy's substitution policies entirely.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming YMS-391 was found in the public sources searched. NavSource states no DANFS history exists for this hull; no Wikipedia article exists; the hull was never renamed and has no AMS-era documentation. No asbestos-content assertion about this hull was found in any authoritative source.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. Deck logs (1943-46) exist at NARA College Park but are not digitized; builder work packages for a defunct small yacht yard are not located in public sources; post-sale fate unknown. Does not establish or defeat any claim of exposure or legal eligibility.
