E.I. DuPont de Nemours — Plants in Washington

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that they were exposed to asbestos while working at E.I. DuPont de Nemours plants in Washington. This page documents the Washington portion of E.I. DuPont de Nemours’s multi-state operations. For the full corporate summary and plants in other states, see the E.I. DuPont de Nemours manufacturer page.

Premises Description

E.I. DuPont de Nemours and Company (founded 1802 — originally as a black-powder manufacturer near Wilmington, Delaware; today operated as multiple successor entities including DuPont de Nemours Inc., Chemours, Corteva, and others) was through the 20th century one of the largest and most diversified U.S. chemical and industrial manufacturers. DuPont operated major U.S. asbestos-era manufacturing complexes including:

  • Wilmington DE — corporate headquarters and the historic Chambers Works (Deepwater NJ)
  • Beaumont TX — Sabine River petrochemical and polymer operations
  • Belle WV — major specialty chemicals
  • Memphis TN — Memphis Plant chemicals
  • Old Hickory TN — synthetic fibers
  • Parkersburg WV — Washington Works fluoropolymers
  • Dozens of specialty plants across the Mid-Atlantic, Gulf Coast, and Midwest

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that DuPont — as premises owner of its U.S. chemical and industrial complexes — exposed contractor pipefitters, insulators, boilermakers, and trade workers, as well as DuPont’s own operating and maintenance employees, to asbestos through pipe covering, refractory insulation, gaskets and packing, spray-applied fireproofing, and ceiling and partition board across plant utility systems and process units.

E.I. DuPont de Nemours has been named as a Premises Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.

Workers Exposed

  • Chemical-plant pipefitters and refinery pipefitters (UA Local members) at DuPont sites
  • Insulators (HFIAW Local members) on DuPont construction and turnaround crews
  • Boilermakers (IBB Local members) building DuPont process units
  • DuPont’s own operating and maintenance workforce
  • Construction-trade workforces on DuPont EPC projects

If You Worked at a DuPont Complex

If you worked at an E.I. DuPont de Nemours chemical, explosives, plastics, or synthetic-fiber complex during the asbestos era — as a DuPont employee or as a dispatched contractor pipefitter, insulator, boilermaker, or trade worker — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness, you may have legal rights.

Named Plants and Operating Era

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that specific named DuPont plants in Washington allegedly involved asbestos-containing materials during their principal operating eras. Documented plant footprint in Washington:

  • DuPont Powder Works (DuPont WA) — in DuPont WA (Pierce County, on Puget Sound south of Tacoma), historic dynamite and industrial-explosives plant allegedly operating from 1909 through 1976. The company town of DuPont WA was literally built to house plant workers; site closure in the mid-1970s ended explosives production and the land was progressively redeveloped (subsequently Weyerhaeuser corporate campus and residential DuPont community).
  • DuPont WA Powerhouse and Support Buildings — in DuPont WA, boiler house, dry houses, glycerin plant, nitrator buildings, and packing houses allegedly operating in support of the explosives-manufacturing works during the same era.

Plant-Era ACM Narrative

At DuPont’s Washington operations, plaintiffs alleged the following plant-era asbestos exposure pathways during the principal U.S. asbestos era (approximately 1930s-1976):

  • Asbestos boiler lagging, asbestos block, and asbestos pipe covering on the DuPont Powder Works powerhouse boilers, steam headers, and superheater piping
  • Asbestos pipe covering on the process piping serving nitrator buildings, glycerin plant, and dynamite packing houses
  • Asbestos-refractory brick and asbestos block on the acid concentrator (nitric / sulfuric) columns and heat exchangers
  • Asbestos compressed-sheet gaskets and asbestos braided packing at flanged process connections, pumps, and valves throughout the explosives complex
  • Asbestos-cement transite panels and asbestos millboard in the powerhouse and electrical distribution rooms

Trades and Local Union Coverage

Plaintiffs alleged that Washington DuPont plant work was performed by tradesmen from the following unions and Locals during the asbestos era:

  • HFIAW Insulators Local 7 — Seattle / Puget Sound WA jurisdiction — asbestos pipe covering and block insulation at DuPont WA Powder Works
  • UA Pipefitters Local 26 — Tacoma / South Puget Sound jurisdiction — flange bolt-up, gasket work, and process piping at DuPont WA
  • IBEW Electricians Local 76 — Tacoma / Pierce County jurisdiction — switchgear, motor-control center, and lighting-in-hazardous-locations work at DuPont WA
  • BAC Bricklayers — the Tacoma-area Local — refractory relining of powerhouse boilers and acid-concentrator columns
  • International Brotherhood of Boilermakers — the Tacoma-area Local — powerhouse and pressure-vessel work at DuPont WA
  • DuPont’s own operating and maintenance workforce — DuPont WA company-town production crews during the asbestos era
