- Yard presence is documented at Philadelphia (1930-31 decommissioning) and Puget Sound Navy Yard (1944 conversion); DANFS does not describe materials removed or installed during those periods and does not establish asbestos work or exposure. The 1938 decommissioning is dated but its site is not explicitly stated (the ship arrived Charleston mid-December 1937).

- NARA's Ship Plan Index lists HATFIELD DD-231 in Record Group 19 under Alphabetical Ship Drawings (NAID 559623) and Microfilm (NAID 175669339). These collections are leads for examining ship-specific plans, including any available insulation and piping drawings.

[4]Internet Archive item dd231bogp1919, 'USA - DD-231 USS Hatfield Booklet of General Plans (1919)', New York Shipbuilding Co., Camden, N.J.; NARA RG 19 provenance [other_primary]

- Finding type
- historical_record
- Finding
- A five-sheet Booklet of General Plans dated 1 January 1919, drawn by New York Shipbuilding Co. for Destroyers #231 to 235 (title block: 'Finished Plan 42-A', 'Booklet Plan 5', with a Bureau of C&R stamp), is publicly digitized on the Internet Archive, sourced from NARA RG 19 'Alphabetical Series of Ship Engineering Drawings, 1789-1967.' The set is incomplete (cover photo; cover sheet and midship section; outboard profile; inboard profile, sections and main deck; bridges, platforms and hold). The sheets reviewed are structural and arrangement drawings labeling spaces such as the engine room and boiler room; no materials or insulation schedule was located in this digitized set.

- Limitations
- The booklet is a genuine ship-family primary document (covers DD-231 through DD-235) but is an incomplete five-sheet set of arrangement drawings; material and insulation specifications (NARA S39 insulation/lagging, S48 piping series) are not part of this set. Its absence of a materials schedule is not evidence that asbestos was or was not aboard. Handwritten annotation prevents full-text search; review was visual at reduced resolution.

- Finding
- NARA's research guide describes potential asbestos-relevant Navy record groups for the 1941-1961 period, including RG 19 destroyer General Information Books and S39 insulation/lagging and S48 piping drawings. It states that deck logs and muster rolls do not directly show asbestos aboard ships.

[6]DANFS specifications block (Clemson class; 1918-19 construction; 35 kt steam destroyer) read with NARA, 'Researching Asbestos aboard US Naval Vessel up through 1961' [other_primary]

- DANFS specifications block; NARA guide, Cartographic Branch section (S39/S48 drawing series)
- Finding type
- asbestos_application
- Finding
- Era/class inference only: a Clemson-class destroyer built in 1918-19 with steam propulsion would have carried the period-standard materials expected of a World War I-program flush-deck destroyer - boiler and machinery insulation, steam-line lagging, gaskets and packing, and fireproofing - products of the kind the NARA asbestos guide identifies as the typical documentation subjects for this era's vessels. This context prioritizes archival leads; it is not a finding that asbestos was installed aboard this hull.

- Class/era inference only. No ship-specific source reviewed documents asbestos aboard DD-231, and this row does not establish that it was present; it describes only what the era and steam propulsion would lead a researcher to look for in the S39/S48 drawings and GIB.
