About Olin Corporation East Alton Missouri

Olin Corporation is a Connecticut-incorporated industrial conglomerate built on chemical and munitions manufacturing. It formed in 1954 through the merger of Olin Industries and Mathieson Chemical Corporation and ran continuous operations at its East Alton, Illinois campus through the mid-twentieth century and beyond. The East Alton site sits in Madison County, Illinois, directly across the Mississippi River from Missouri. It was one of Olin’s primary manufacturing locations — hundreds of acres, thousands of workers at peak production.

Major operations generating asbestos exposure included the Winchester Ammunition Division — rifle cartridges, shotgun shells, and small arms ammunition production requiring extreme heat control managed with asbestos throughout; Chemical manufacturing operations including phosphate and explosive compound processing; and Boiler houses, utility corridors, and maintenance shops — where older asbestos materials were continuously disturbed during repair and renovation work. Thousands of workers were on site simultaneously at peak operations; additional thousands cycled through as contractors, tradespeople, and construction laborers. The heaviest asbestos installation and use occurred from 1930 through mid-1970s, with substantial asbestos handling continued through demolition and remediation work into the 1990s.

The East Alton facility was energy-intensive by design with precise temperature controls for ammunition manufacturing, continuous steam generation for power and process heat, chemical processing at extreme temperatures, and fire safety management around explosive materials. Those requirements drove asbestos into every corner of the plant. Common asbestos applications at the facility included insulation on steam lines running through miles of pipe distribution networks, boiler and furnace wrapping with calcium silicate insulation block, refractory linings in ovens and furnaces rated for extreme heat, gaskets and mechanical seals, floor tiles and adhesives, roofing materials and tar compounds, electrical switchgear insulation, sprayed-on fireproofing applied directly to structural steel, and thermal insulation around high-temperature processing equipment.

General Equipment at Olin Corporation East Alton 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 Olin Corporation East Alton Missouri

Every trade working inside this facility had asbestos exposure. Some faced near-constant exposure for entire careers. Insulation workers (pipecoverers and insulators) represented the highest-exposure trade at any industrial site. Workers who built, renovated, maintained, or repaired the facility during the 1930–1973 window accumulated the greatest total fiber exposure. Olin made no meaningful effort to limit exposures, segregate contaminated work areas, or provide respiratory protection during that entire period.

Exposure remained at dangerous levels through the 1990s. Workers who cut through old asbestos pipe insulation including pipe covering and aged calcium silicate insulation, tore out vinyl asbestos floor tiles, replaced deteriorated boiler insulation, stripped worn pipe insulation or pipe covering products during renovation, removed asbestos gaskets from equipment, and demolished or renovated structures with sprayed asbestos fireproofing received concentrated, acute exposures every bit as dangerous as the chronic long-term exposures of earlier decades.

Boiler room workers ranked among the most heavily contaminated. A maintenance pipefitter tearing out degraded calcium silicate insulation in a boiler room did not receive a dust mask rated for asbestos. He worked in a confined space with no ventilation. The insulation crumbled in his hands. He breathed that air all day. He brought that dust home on his clothes. His wife shook it out doing laundry. His kids sat next to him at dinner.

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.

Cross-State & Regional Corridor Workers

The East Alton facility pulled workers from both sides of the Mississippi. Workers from St. Louis, St. Charles County, Jefferson County, and surrounding Missouri communities commuted daily or took jobs as traveling tradespeople at this site. Missouri residents who worked at Olin’s East Alton plant can file legal claims in Missouri courts.
