The Dow Chemical Company — Plants in Louisiana

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

Premises Description

The Dow Chemical Company (founded 1897, headquartered Midland, Michigan; today operating as Dow Inc.) was through the 20th century one of the largest U.S. petrochemical and specialty chemical manufacturers. Dow operated major U.S. asbestos-era manufacturing complexes at:

  • Midland MI — the historic corporate headquarters and original specialty-chemicals complex
  • Freeport TX — Dow Texas Operations, one of the largest petrochemical complexes in the world
  • Plaquemine LA — Dow Louisiana Operations, major chlor-alkali and ethylene production
  • Pittsburg CA — West Coast specialty chemicals
  • Carrollton KY, Hahnville LA, Russellville AR, and numerous specialty sites

Each of Dow’s major complexes operated continuously through the asbestos era with extensive asbestos-containing materials specified across process units, utility systems, and plant infrastructure.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Dow Chemical — as premises owner of its U.S. petrochemical and specialty chemical complexes — exposed contractor pipefitters, insulators, boilermakers, and trade workers, as well as Dow’s own operating and maintenance employees, to asbestos through:

  • Asbestos pipe covering on miles of plant steam mains, hot-oil lines, and process piping
  • Asbestos refractory and block insulation on process heaters, furnaces, and reformers
  • Asbestos gaskets and packing at process flanges, manways, and pump and valve seals
  • Spray-applied asbestos fireproofing on plant structural steel
  • Asbestos ceiling and partition board in plant control rooms, office buildings, and lab facilities

Dow Chemical Company has been named as a Premises Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.

Workers Exposed

  • Refinery and petrochemical pipefitters (UA Local members) working Dow turnarounds and capital projects
  • Insulators (HFIAW Local members) on Dow construction crews
  • Boilermakers (IBB Local members) building Dow process units
  • Dow’s own operating and maintenance workforce (USW Local representation)
  • Construction-trade workforces on Dow EPC projects (Brown & Root, Fluor, Bechtel-built Dow units)

If You Worked at a Dow Chemical Complex

If you worked at a Dow Chemical Company petrochemical or specialty chemical complex during the asbestos era — at Midland MI, Freeport TX, Plaquemine LA, Pittsburg CA, or any other Dow facility — as a Dow 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.
