- Finding type
- vessel_history
- Finding
- DANFS reports Percival operated chiefly off the West Coast, avoided grounding at Honda Point on 8 September 1923 and helped rescue survivors, later became flagship of Destroyer Squadron 11, and sustained only minor damage in a 31 January 1926 collision with William Jones (DD-308).

- Limitations
- Operational history does not document a shipyard repair scope or identify asbestos-containing material. The DANFS date of 12 September 1925 for becoming squadron flagship is incongruent with its 'following the Honda Point disaster' wording; the precise year is excluded pending a contemporaneous record.

[3]U.S. Bureau of Standards, Commercial Standards Monthly, 15 January 1929, American Marine Standards section [other_primary]

- PDF page 11, printed page 10, 'American Marine Standards,' paragraph 19
- Finding type
- asbestos_application
- Finding
- A January 1929 U.S. Bureau of Standards bulletin reports distribution of American Marine Standards Committee specifications for insulation of ship piping and machinery, magnesia-asbestos plaster, and asbestos millboard. This documents marine-industry materials available during the latter part of Percival's service, not installation on the vessel.

- Limitations
- Supports only the era-level marine-material context used for tier 2. These are general marine standards published about eleven years after this ship was laid down; the bulletin does not establish Navy adoption, installation on Percival, asbestos presence, product quantity, or crew exposure.

- General Information Books and Cartographic Branch sections, RG 19 Entry P 9 and 19-Hull
- Finding type
- historical_record
- Finding
- NARA's naval asbestos research guide identifies RG 19 ship engineering drawings arranged by hull number, including possible S39 insulation and lagging drawings, and RG 19 Entry P 9 destroyer general information books as avenues for checking hull materials. The guide notes that such drawings and books are incomplete; no DD-298 drawing or book was retrieved for this review.

- Limitations
- NARA describes record series, not an identified DD-298 item. Its introductory discussion emphasizes 1941-1961, after this ship's 1930 decommissioning; an onsite inventory check would be needed to establish whether relevant earlier documents survive.

[6]CourtListener authenticated API v4 search, four query/type combinations, 27 September 2026; hit dockets Abella v. Simon, No. 1:11-cv-20152 (S.D. Fla.) and United States v. Anderson, No. 1:05-cv-00637 (D. Colo.) [court_record]

- Finding type
- litigation_documented
- Finding
- Authenticated CourtListener API v4 opinion and RECAP docket searches for exact ship name 'USS Percival' and hull number 'DD-298' found no qualifying asbestos litigation naming this hull. Name searches returned zero results. The hull-number docket search returned two unrelated cases: Abella v. Simon (civil rights) and United States v. Anderson (interpleader); both are OCR false positives rather than references to DD-298.

- Limitations
- This is a bounded search of indexed opinions and RECAP dockets, not proof that no unindexed pleading, state-court case, or other litigation exists. The two hull-query hits are OCR matches in unrelated litigation; neither alleges shipboard exposure. No merits-level exposure finding is inferred.
