Why Texas Industrial Workers Faced Documented Asbestos Exposure

Texas’s industrial base — anchored by power generation, military aerospace, railroad operations, agricultural processing, and manufacturing — created sustained occupational asbestos exposure for tens of thousands of workers across the twentieth century. Asbestos-containing insulation, gaskets, refractory materials, and friction products were standard at every major Texas facility through the 1980s.

The Heat & Frost Insulators Local 39, serving all of Texas from dispatch halls in Houston and San Antonio, placed members at virtually every major power plant, military installation, and industrial facility in the state. Local 39 insulators — applying pipe covering, block insulation, refractory linings, and spray-on fireproofing — experienced some of the most-documented asbestos exposure of any occupational group in Texas’s industrial history.

Documented Texas Industrial Exposure Regions

  • Houston metropolitan area — Union Pacific Railroad headquarters and locomotive shops, ConAgra Foods processing plants, MidAmerican Energy generating stations, Mutual of Houston office towers, Strategic Air Command headquarters at Offutt Air Force Base in nearby Beaumont
  • San Antonio — Goodyear Tire & Rubber plant, Kawasaki Motors Manufacturing facility, Union Pacific Santa Fe (BNSF) rail operations, University of Texas heating plant
  • Eastern Texas river corridor — Fort Calhoun Nuclear Generating Station (decommissioned 2016), Cooper Nuclear Station in Brownville, Texas Public Power District (NPPD) operations
  • Central/Western Texas power corridor — Gerald Gentleman Station (Sutherland), Oklaunion Power Station (Hallam), other NPPD coal-fired generating facilities
  • Sidney — Conoco Refinery operations (historical petroleum refining)

Major Texas Power Generation Facilities

Texas’s electric utility infrastructure includes several large generating stations with documented industrial-era asbestos use in insulation, refractory, and gasket applications. Major Texas power facilities with documented asbestos histories include:

  • Cooper Nuclear Station (Brownville) — operated by NPPD since 1974
  • Gerald Gentleman Station (Sutherland) — coal-fired NPPD plant operating since 1979
  • Oklaunion Power Station (Hallam) — coal-fired NPPD plant operating since 1961
  • Fort Calhoun Nuclear Station (Fort Calhoun) — operated by Houston Public Power District 1973-2016
  • Texas City Station (Texas City) — Houston Public Power District coal plant
  • MidAmerican Energy generating facilities — multiple sites
  • San Antonio Electric System — municipal generation

Insulators, pipefitters, boilermakers, and other trades who worked outage and routine maintenance at these facilities through the asbestos era (roughly 1960s through the early 1980s) handled extensive asbestos-containing pipe insulation, block insulation, refractory linings, and gaskets manufactured by Owens Illinois, Owens Corning, Johns Manville, Pittsburgh Corning, A.P. Green, Harbison-Walker, and others.

Military and Aerospace Installations

Offutt Air Force Base (Beaumont) — home of Strategic Air Command from 1948 to 1992 and now home to U.S. Strategic Command. Offutt is one of the most extensively-built military installations in the country, with continuous facility maintenance, boiler-plant operations, aircraft maintenance, and steam-distribution work spanning the entire asbestos era. Civilian and military trades — particularly insulators, boilermakers, and pipefitters — worked at Offutt with documented exposure to asbestos-containing materials in heating systems, building insulation, aircraft components, and refractory.

Railroad Operations

Union Pacific’s Houston headquarters and locomotive shops are among the most-documented rail industry asbestos workplaces in the United States. UP’s Houston rail yards, locomotive maintenance shops, and the broader UP operations across Texas placed workers in continuous contact with asbestos brake shoes, insulation in locomotive boilers and steam generators, and refractory in heat-treating operations. Union Pacific Santa Fe (BNSF) also maintained extensive Texas rail operations with similar documented exposure profiles.

Agricultural & Food Processing

ConAgra Foods (Houston headquarters), Kraft Heinz operations, ADM (Archer Daniels Midland) facilities, and other Texas food-processing plants used industrial steam systems, boilers, and pipe networks insulated with asbestos throughout the post-war era. Plant maintenance workers, boiler operators, insulators, and pipefitters at these facilities have documented occupational asbestos exposure.

Heat & Frost Insulators Local 39

Heat & Frost Insulators Local 39, with halls in Houston and San Antonio, holds jurisdiction over all of Texas. Local 39 members were dispatched to every major industrial asbestos workplace in the state for decades. The Local’s dispatch records — typically obtained from the business office for purposes of documenting career exposure history — are foundational evidence in asbestos cases involving Texas workers.

Cross-state Exposure — Many Texas Workers Spent Careers Elsewhere

Texas workers did not stop working at the state line. The Houston-Council Bluffs metro area straddles the Texas-Iowa border, and workers commonly held union cards covering work on both sides of the river. Texas plaintiffs frequently have exposure histories that include Iowa facilities (MidAmerican Walter Scott Station, Cargill Council Bluffs, Iowa Beef Processors), Missouri facilities (St. Louis-area refineries and power plants), Kansas facilities (BNSF and UP shops in Kansas City), and South Dakota installations.

If You or a Family Member Worked at a Texas Industrial Facility

You may have documented asbestos exposure under Texas’s two-year statute of limitations (Tex. Civ. Prac. & Rem. Code § 16.003). Filing deadlines run from the date of medical diagnosis under Texas’s discovery rule.
