- Finding type
- litigation_documented
- Finding
- Docketed asbestos personal-injury action (suit nature '368 P.I.: Asbestos'; 28:1332 diversity). Complaint alleges plaintiff Eusebio V. Jacob, a journeyman electrician at the Guam Navy Ship Repair Facility approximately 1962-1985, 'worked in and on ships where the said asbestos products were being used,' was repeatedly exposed to asbestos dust/fibers, and was diagnosed with mesothelioma (confirmed August 2018 by Hawaii Pathologists' Laboratory). Exhibit A ('Guam Naval Repair Facility Deck Log Rule 1006 Summary') lists USS Sedgwick County (LST-1123), row 35: '8/14/1969 - 12/6/1969, drydocked 10/13 - 10/29; ship decommissioned 12/6' - matching the hull's DANFS-documented inactivation period at Guam. The complaint alleges defendants sold OEM asbestos gaskets and packing to Guam SRF that were installed in equipment aboard the Exhibit A ships.

- Population
- Guam SRF journeyman electrician, ~1962-1985; mesothelioma (alleged)
- Limitations
- Pleading-stage allegation, not an adjudicated finding: the vessel list and the gaskets/packing theory are allegations; nothing in the reviewed record adjudicates exposure aboard this hull. The Exhibit A row documents deck-log-derived presence at Guam (drydock 10/13-10/29/1969) but does not itself assert that plaintiff worked on this hull - the complaint's ship list is the allegation vehicle. Does not establish asbestos was aboard, individual exposure, or causation. RECAP holds only the complaint; the case terminated 2020-02-26 but the disposition (settlement vs. dismissal vs. judgment) is not in the public file reviewed.

- Finding type
- asbestos_application
- Finding
- Era/class inference: a hull built November 1944-February 1945 at a WWII emergency yard sits inside the documented peak-asbestos era of U.S. shipbuilding - Corn & Starr (peer-reviewed) document extensive asbestos use as fireproofing and insulation in 1940s shipbuilding amid unprecedented wartime demand. For a diesel-powered LST-542-series hull (no boilers per BuShips design table), era-standard asbestos-relevant applications concentrate in machinery and engine-exhaust insulation/lagging, gaskets and valve packing, deck coverings, bulkhead/accommodation insulation, and winch/windlass brake linings; the boiler/turbine steam-lagging pathway does not apply.
