About Owensville R-III Owensville Missouri
Owensville R-III sits in Gasconade County, 70 miles west of St. Louis. Like virtually every Missouri public school built between the 1940s and late 1970s, this building went up during the era when asbestos was the specified material for insulation and fireproofing. Architects called for products including pipe insulation, gaskets and packing, and ceiling tile. Contractors installed them throughout the building. The manufacturers knew these products would be disturbed repeatedly over the building’s operational life. They shipped them anyway.
The Missouri Boiler Registry documents a fired AO Smith water heater at Owensville R-III, registered 1988, located in the boiler room and used for hot-water heating. That system did not operate in isolation. It included distribution piping, expansion tanks, valves, flanged connections, circulator pumps, and associated insulation—virtually all manufactured with asbestos-containing materials in a building of this vintage.
Missouri Department of Natural Resources NESHAP notification records document eight total asbestos-related projects at Owensville R-III: two formal abatement projects, three courtesy notifications, and three demolition or renovation notifications. The facility contained over 60,000 square feet of installed asbestos-containing floor material including Gold Bond and Pabco brand products, 5-10 linear feet of friable pipe insulation including Thermobestos and calcium silicate products, asbestos-coated mudded fittings supplied under the Superex brand name, 87 linear feet of friable duct tape in HVAC systems, asbestos gaskets at flanged connections throughout the distribution system, and valve stem packing supplied under the Cranite brand.
General Equipment at Owensville R-III Owensville Missouri
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
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri DNR) 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.

Who May Have Been Exposed at Owensville R-III Owensville Missouri
Boilermakers who serviced and repaired the hot-water heating system replaced boiler door gaskets manufactured with asbestos-containing material and stripped deteriorated pipe insulation from valves and fittings to access components, generating heavy fiber releases in the enclosed boiler room. Members of Heat and Frost Insulators Local 1 (St. Louis) and Boilermakers Local 27 (St. Louis) carried the heaviest exposure load.
Pipefitters and Steamfitters who maintained the hot-water distribution system repacked valve stems with asbestos packing material, removed calcium silicate pipe insulation and Thermobestos insulation to access joints requiring repair, and cut pipe insulation with utility knives, generating airborne fiber. They worked in boiler rooms, basements, and ceiling chases—the highest-concentration spaces in the building. Members of Plumbers and Pipefitters UA Local 562 (St. Louis) and UA Local 268 (Kansas City).
Insulators applied or removed pipe covering, fitting insulation, and duct insulation—cutting and fitting product that shed fibers continuously and removing deteriorated insulation, the task that generates peak fiber release. They worked with bare hands in boiler rooms and basements without respiratory protection. Members of Heat and Frost Insulators Local 1 (St. Louis) and Local 27 (Kansas City). HVAC Mechanics cut into insulated duct, replaced friable duct tape at joints, and worked inside air handling units during maintenance. Electricians drilled through asbestos-containing floor tile and mastic on every penetration and routed conduit through walls and ceilings in mechanical spaces, disturbing pipe insulation and other friable materials. Millwrights and General Maintenance Workers pulled floor tiles for flooring repairs, patched deteriorated pipe insulation, replaced Cranite gaskets and valve packing, and performed general renovation in mechanical spaces, typically receiving no trade-specific hazard training and no respiratory protection.
Critical Filing Deadline & Next Steps
Missouri law gives mesothelioma and asbestos-disease claimants 5 years from the date of medical diagnosis to file a personal-injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). 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 Missouri 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
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.
