General Equipment at Kennett 39 Kennett 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.

No Missouri DNR 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 Kennett 39 Kennett Missouri

Asbestos does not harm people sitting in offices. It harms the people who disturb it — who cut it, strip it, saw it, grind it, or work in its settled dust day after day. At Kennett 39, that meant skilled tradesmen whose daily work put them directly inside these mechanical systems.

Boilermakers — Direct, Concentrated Exposure

The Brunner and Bryan boilers at Kennett 39’s Middle School and Vo-Ed building required regular service. Boilermakers who worked these units encountered asbestos insulation in its most concentrated form:

  • Removing outer jacketing and Thermobestos block insulation from boiler fireboxes to reach internal tubes and refractory
  • Chipping, prying, and sweeping crumbled asbestos block from enclosed boiler rooms with minimal mechanical ventilation
  • Installing replacement Thermobestos and calcium silicate pipe insulation insulation after tube work — cutting, fitting, and trimming asbestos products in the same confined space
  • Servicing Crane Cranite gaskets in flanged connections and boiler feed lines
  • Stripping and replacing Superex packing in pump shaft seals — work that released concentrated asbestos dust in tight quarters

The Boiler Registry records confirm long-term exposure for workers who maintained these boilers across the 1969–2000+ operational period.

Pipefitters (UA Local 562 and Local 268) — Linear Exposure Across Entire Building Systems

Miles of hot-water distribution piping connected the Kennett 39 boilers to radiators, fan coil units, and air handling equipment throughout the buildings. Every inch of that piping was covered in asbestos insulation. The documented exposure includes:

  • 2,500 linear feet of friable calcium silicate pipe insulation and Thermobestos pipe insulation at one project alone
  • 1,006 additional linear feet of calcium silicate pipe insulation and high-temperature pipe insulation at a second facility
  • Preformed half-round insulation sections — scored with a utility knife, broken apart, and removed by hand in confined spaces
  • Crane Cranite gaskets and Superex packing — installed in every elbow, tee, and flanged connection; removed and replaced during maintenance

Pipefitters working on these systems disturbed asbestos-containing products every time they:

  • Cut into a hot-water line to replace a valve or fitting
  • Repaired a pressurized system leak, stripping away calcium silicate pipe insulation insulation to access the joint
  • Repacked a flanged connection with Crane Cranite gasket material
  • Mixed and applied asbestos-containing finishing cement to seal insulation seams
  • Accessed air plenum spaces to service hydronic heating connections

Union members from Plumbers and Pipefitters UA Local 562 and UA Local 268 documented exposure to these specific products during service calls to Kennett 39 and comparable school district mechanical systems. The measurements in the MDNR records reflect only what was formally notified for abatement — not the full scope of what was installed and disturbed across decades of active maintenance, particularly through the 1970s–1990s.

Insulators (Heat and Frost Insulators Local 1) — Sustained, Concentrated Exposure

Insulators faced the most concentrated asbestos exposure of any trade at Kennett 39:

  • Sawing preformed calcium silicate pipe insulation and Thermobestos sections to length with hand saws in boiler rooms
  • Cutting mitered fittings around pipes and elbows with utility knives and snips
  • Finishing joints with canvas jacketing and asbestos-containing finishing cement — frequently labeled 5–15% chrysotile asbestos
  • Removing degraded calcium silicate pipe insulation insulation from pipes and boiler surfaces during system rebuilds, releasing airborne fibers from crumbling 20–40-year-old material
  • Handling material classified as friable in MDNR records — material that crumbles under hand pressure and releases fibers without any mechanical disturbance

Friable pipe insulation and friable spray texture carry the highest fiber-release risk of any asbestos material category. Heat and Frost Insulators Local 1 members who worked with and products at Kennett 39 received direct, heavy exposure across service careers spanning multiple decades.

HVAC Mechanics — Enclosed-Space Exposure

HVAC mechanics servicing air handling units and ductwork disturbed asbestos directly:

  • Changing coils and replacing damper actuators in air handling units surrounded by asbestos insulation
  • Cutting into duct runs lined with high-temperature pipe insulation or combination asbestos products
  • Accessing air plenum insulation — spray-applied fireproofing spray or batting material applied in confined mechanical spaces
  • Working above suspended ceilings containing 2,500 square feet of friable asbestos spray texture during routine ceiling access and fixture replacement
  • Sealing ductwork with mastic products containing asbestos

Disturbance of air plenum insulation inside a confined air handling unit produced some of the most intense localized fiber concentrations in any school maintenance scenario.

Electricians — Exposure No One Warned Them About

Electricians at Kennett 39 were never told the ceiling tiles they pushed aside and the mechanical spaces they worked in were lined with asbestos. Their exposure came from:

  • Working above suspended ceilings containing friable ceiling tile asbestos tile and spray texture — disturbing both products every time they accessed the plenum for conduit runs or junction boxes
  • Running conduit through mechanical rooms insulated with Thermobestos and calcium silicate pipe insulation
  • Drilling through Gold Bond asbestos-reinforced gypsum board for panel rough-ins and device boxes
  • Working alongside insulators and pipefitters whose trade work created asbestos dust that settled on everyone in the room

Electricians consistently underestimate their asbestos exposure because they were never the ones handling the insulation. The exposure was bystander exposure — and bystander exposure to these products caused

Missouri Boiler and Pressure Vessel Registry — Equipment on File

The following boilers and pressure vessels were registered with the Missouri Department of Labor and Industrial Relations (DOLIR) for this facility. These are public records and have been introduced in asbestos exposure litigation to establish the presence of industrial heating and process equipment — and the contractors and inspectors who serviced it — at this site.

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

  1. 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.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. 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.
  4. 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.
