About Lake City Army Ammunition Plant
Lake City Army Ammunition Plant is a government-owned, contractor-operated (GOCO) facility in Independence, Missouri, covering approximately 3,935 acres in Jackson County. It has operated continuously since 1941, when Remington Arms constructed it as part of the World War II defense buildup. It is one of the largest small-caliber ammunition manufacturing facilities in the United States. Successive operators have included Remington Arms (original builder and operator), Olin Corporation, Honeywell, Allied Signal, Alliant Techsystems (ATK), Vista Outdoor, and Olin Winchester (current). The facility contains hundreds of individual buildings across manufacturing, maintenance, utility, and administrative areas. LCAAP has produced billions of rounds of small-caliber ammunition for the U.S. military and allied forces across nearly eight decades of continuous operation.
LCAAPwas built in 1941 and expanded through the 1970s — the same decades when asbestos-containing materials dominated American industrial construction. The plant’s operations required high-temperature steam systems, extensive piping networks, heavy mechanical equipment, and large production floor areas. Each of those systems routinely incorporated asbestos-containing materials as a matter of standard industrial practice during that era.
Ammo manufacturing requires precise temperature control for case annealing, chemical treatments, and propellant handling. These processes depend on steam distribution systems running pipe networks throughout the facility. Steam pipes operating at high temperatures and pressures were routinely insulated with asbestos-containing products — including calcium silicate insulation, pipe covering, and pipe insulation — applied as sectional pipe covering, fitting covers, and mudded joint compounds throughout the facility, including Building 1 and interconnecting pipe runs.
Producing ammunition, propellants, and pyrotechnic materials generates static electricity that can trigger catastrophic explosions. Production buildings at LCAAP reportedly used specialized conductive flooring to dissipate static charges. Large ammunition plants require substantial boiler capacity for heating and process steam. Boilers, boiler room pipe runs, flanges, valves, and associated equipment were routinely insulated with asbestos-containing materials from the relevant period.
General Equipment at Lake City Army Ammunition Plant
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 Lake City Army Ammunition Plant
Workers who installed, maintained, repaired, or removed pipe insulation — or who worked in proximity to deteriorating or disturbed pipe insulation — may have been exposed to asbestos-containing materials. Workers engaged in equipment insulation work on boilers, heat exchangers, pressure vessels, pumps, turbines, and other stationary mechanical equipment faced exposure risks. Workers who performed floor maintenance, renovation, or repair work involving friable asbestos-containing conductive flooring in production buildings, including Building 1, Buildings B1, B2, B3, Buildings 38B and 38C, and Building 56C, were exposed. Workers disturbing mudded joint fittings, elbow covers, and valve covers during routine maintenance faced among the highest-exposure tasks.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.
