Dow Chemical Freeport: The Western Hemisphere’s Largest Chemical Complex
Dow Chemical began operations in Freeport in 1940, drawn by the area’s brine deposits and proximity to the Gulf. The Freeport complex grew to encompass over 5,000 acres with dozens of individual plants producing everything from chlorine and caustic soda to ethylene, plastics, and agricultural chemicals. At peak operation, the site employed over 8,000 direct workers with thousands more contract maintenance workers cycling through turnarounds.
Asbestos insulation was integral to the high-temperature process equipment, boilers, heat exchangers, and pipe systems throughout the Dow complex. Maintenance contractors — primarily pipefitters, insulators, and boilermakers from Brazoria County union halls — performed the insulation work throughout the 1950s, 1960s, and 1970s using products from manufacturers including Owens Corning (Kaylo), Pittsburgh Corning (Unibestos), and Johns-Manville. These companies were aware of the health dangers of their products during this period but withheld that information from contractors and workers.
BASF and Celanese: Corridor Exposure Across Multiple Plants
Workers who maintained the Brazosport chemical corridor rarely worked at a single facility. Maintenance contractors moved between BASF, Dow, Celanese, and PPG operations throughout their careers, accumulating compound exposure across multiple asbestos-insulated facilities. This cross-facility exposure pattern is legally significant: each manufacturer of each asbestos product used at each facility is a potential defendant in mesothelioma litigation, multiplying the number of trust fund claims and lawsuit defendants an experienced attorney can pursue.
Occupational Groups at Risk
- Pipe coverers and insulators — direct handling of raw asbestos insulation on all chemical plant piping
- Pipefitters — installation and maintenance in heavy asbestos-laden environments
- Boilermakers — boiler repair involving asbestos rope, blanket, and block insulation
- Operators and process technicians — daily ambient exposure from deteriorating pipe insulation
- Construction workers — plant expansion crews working alongside insulation trades
- Electricians — electrical equipment with asbestos panel linings and wire insulation
