About Dow Chemical Terre Haute Operations Terre Haute Indiana
Dow Chemical’s Terre Haute Operations was one of the largest industrial employers in Vigo County, Indiana, and the broader Wabash Valley region throughout the twentieth century. Situated along the Wabash River corridor, Terre Haute drew chemical manufacturing investment because of proximity to raw materials and supply sources, established rail and water transportation infrastructure, a skilled and organized industrial labor force, and strategic location for regional and national distribution. The Wabash Valley industrial corridor was part of Indiana’s broader manufacturing economy that — alongside the steel corridor anchored by U.S. Steel Gary Works, Bethlehem Steel Burns Harbor, and Inland Steel East Chicago in northwest Indiana, and engine manufacturing centered at Cummins Engine in Columbus — made Indiana one of the most heavily industrialized states in the nation during the mid-twentieth century.
Dow Chemical’s Terre Haute facility was a large-scale continuous-process chemical manufacturing complex that reportedly encompassed reactor systems — large pressurized vessels for chemical synthesis reactions, reportedly insulated with Thermobestos and pipe insulation asbestos-containing pipe insulation; distillation columns — tall, heavily insulated fractionation equipment allegedly containing calcium silicate pipe insulation calcium silicate insulation with amosite asbestos; heat exchangers — cooling and heating equipment with thermal insulation reportedly spray-applied fireproofing asbestos-containing fireproofing; boiler systems — steam generation and distribution throughout the facility, reportedly insulated with asbestos-containing refractory materials; and miles of process piping — carrying steam, thermal transfer fluids, and chemical feeds at high temperatures and pressures, reportedly fitted with gaskets and packing materials from gaskets and packing and John Crane. All of this infrastructure was reportedly insulated with asbestos-containing materials as standard industrial practice throughout the facility’s mid-twentieth-century operational period. The facility employed hundreds of maintenance workers, construction tradespeople, and process operators — many of them union members — who may have worked regularly with asbestos-containing materials.
General Equipment at Dow Chemical Terre Haute Operations Terre Haute Indiana
The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.
Documented Asbestos Evidence — Indiana
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Indiana Department of Environmental Management (IDEM) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.
No IDEM NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at Dow Chemical Terre Haute Operations Terre Haute Indiana
Construction and maintenance work at the Dow facility was reportedly performed by skilled union tradespeople affiliated with various locals serving the Wabash Valley and broader Indiana region, including Heat and Frost Insulators and Allied Workers Local 18 — Indiana-based insulators performing pipe covering, block insulation, and related trades at chemical, steel, and manufacturing facilities across the state, including reportedly at the Dow Terre Haute Operations; Boilermakers Local 374 — serving Indiana industrial facilities including chemical plants and power stations in the Wabash Valley region, performing pressure vessel and boiler work involving heavy asbestos-containing insulation; United Steelworkers Local 1014 (Gary) — while based in northwest Indiana’s steel corridor at U.S. Steel Gary Works, USW members across Indiana worked in industrial environments where asbestos-containing materials were reportedly pervasive; United Association of Plumbers and Pipefitters — local affiliates covering Vigo County and the Wabash Valley region, performing piping systems, valves, and steam line work involving asbestos-containing gaskets, packing, and pipe insulation; International Brotherhood of Boilermakers — pressure vessel and boiler work involving asbestos-containing refractory materials and insulation; and International Union of Operating Engineers — equipment operation and maintenance involving asbestos-containing insulation and components.
Indiana union members who worked at the Dow Terre Haute Operations — or who worked alongside contractors doing insulation, boilermaker, or pipefitting work at the facility — may have been exposed to asbestos-containing materials released during installation, maintenance, and removal activities.
Indiana — Filing Deadline & Next Steps
Indiana law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (Ind. Code § 34-11-2-4). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (Ind. Code § 34-23-1-1). The two deadlines run on separate tracks — preserving one does not extend the other.
The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.
Practical first steps
- Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
- Speak with an asbestos attorney with Indiana experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.
Asbestos-Related Diseases — Indiana
Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.
Mesothelioma
A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.
Asbestosis
A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.
Lung Cancer
Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.
Other Recognized Diseases
Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.
If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
