- Limitations
- DANFS documents identity, service history, and specifications, not materials or asbestos content - the narrative contains no asbestos-related content whatsoever. This entry omits the laid-down and stricken dates (carried from NavSource - see ev-02). Mirror transcription cited because the live NHHC page returns 404 (standing link rot, BATCH-01). The 'San Francisco overhaul' is not yard-identified in DANFS; NavSource photo captions place it at Mare Island 12 April-22 May 1945 (ev-02).

- Finding
- NavSource operational record for this hull, compiled from official Navy photographs and logbook data: keel laid 23 February 1943 by Boston Navy Yard, Charlestown, Mass. (date absent from DANFS); launched and christened 6 April 1943 sponsored by Mrs. L. W. Canfield, mother of Ensign Canfield; commissioned 22 July 1943; decommissioned 21 December 1945 at Permanente Metals Co. Yard #2, Richmond, Cal., with the ship's logbook showing 30 November 1945; struck from the Naval Vessel Register 8 January 1946; sold 12 June 1947, scrapped. Dated official Navy photo captions place the hull in overhaul at the Mare Island Naval Shipyard from 12 April until 22 May 1945 (approaching the yard 16 May 1945; new quad 40 mm gun mount visible aft 21 May). Commanding officers: Cmdr. John Belton Cleland, Jr., USNR (22 Jul 1943-31 Dec 1943); Lcdr. Parker Emanuel Cherry, USNR (31 Dec 1943-27 Mar 1945); Lcdr. Robert E. Blackwell, USNR (27 Mar-Nov 1945); Lt. John B. Harris, Jr., USNR/USN (Nov-12 Dec 1945).

The logbook/official decommissioning date conflict is documented, not resolved. Documents yard periods and dates, not materials or asbestos content.

[3]Navypedia, 'GMT' destroyer escorts (EVARTS) member table and design specifications + DANFS specifications block for DE-262 [other_primary]
- Locator
- navypedia us_de_gmt.htm member table row DE262 Canfield + machinery spec block; DANFS DE-262 spec block ('Class: EVARTS')
- Finding type
- asbestos_application
- Finding
- Era/class inference: DE-262 is documented in the GMT (Evarts) member table - Boston N Yd Charlestown, laid 2/1943, launched 6.4.1943, commissioned 7/1943, stricken 1.1946 - matching DANFS and NavSource. The GMT design's machinery is 4 General Motors diesel-generator sets with 2 electric motors, 6,000 hp - a diesel-electric plant with no boilers or steam system. A Navy-yard-built diesel-electric escort completed mid-1943 would have carried era-standard asbestos applications appropriate to that plant: exhaust-system insulation, gaskets and packing throughout engineering spaces, electrical insulation, brake linings on winch/windlass equipment, and deck coverings - not boiler or steam-line lagging.

- Limitations
- Class/era inference only - NOT a hull-specific finding. Navypedia is a secondary reference; the DANFS spec block confirms class (Evarts) but does not state engine type. The diesel-electric plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply. Does not quantify material, does not establish that any specific product was or was not installed aboard this hull, and does not establish any individual's exposure.

- Finding
- Builder/repair/disposal-yard context: the hull was built at Boston Navy Yard (Atlas yard record 'boston-naval-shipyard', tier 3), received an overhaul at Mare Island Naval Shipyard 12 April-22 May 1945 (Atlas yard record 'mare-island-naval-shipyard', tier 2), and was decommissioned at Permanente Metals Co. Yard #2, Richmond - the Kaiser Richmond complex (Atlas yard record 'kaiser-shipyards', tier 3). Yard-level documentation establishes asbestos use at these facilities during the era, not aboard this specific hull.

Yard asbestos documentation does not establish that a particular product was installed on or disturbed aboard DE-262. The Permanente Metals Co. Yard #2 identity rests on NavSource's compiled data (ev-02); the Kaiser yard dataset entry covers the Richmond complex at yard level.

- Archival leads for this hull: NavSource's operational data quotes the ship's logbook (showing decommissioned 30 November 1945 vs the official 21 December), which resides in the NARA 'Logbooks of U.S. Navy Ships and Stations, 1941-1978' series (NAID 594258); WWII War Diaries series holds ship-submitted operational histories for commissioned vessels of this era; NARA RG 19 'General Information Books' are the open lead for hull-level material/insulation specifications. None of these records is digitized or located at hull level for DE-262 in this pass.

- No qualifying ship-specific asbestos record located for DE-262: no hull ACM survey, no abatement contract, no hazmat disclosure, and no qualifying asbestos litigation naming the vessel (CourtListener exact-name opinion and docket queries returned zero; hull-number hits were collision tokens only - see sl-10). Museum/drydock categories cannot apply because the ship was scrapped in 1947 and is not preserved. Law-firm/mesothelioma-marketing pages publish templated 'asbestos exposure' content for this hull name/number (e.g., shepardlawfirm.com, asbestos-ships.com, freeasbestostesting.com); reviewed and excluded as non-authoritative advertising content per the hard sourcing rule.

- Absence of a located public record does not prove absence of asbestos aboard during the 1943-1945 commission - era materials aboard a Navy-yard-built escort are plausible but ship-unproven. Does not establish or defeat any claim of exposure or legal eligibility.
