About Marathon Petroleum Findlay Ohio
Findlay, Ohio has been the corporate home of Marathon Petroleum Corporation, one of the largest petroleum refining, marketing, and transportation companies in the United States. The facility’s history spans more than 130 years:
- Founded 1887: Ohio Oil Company established in Findlay
- Early 1900s–1920s: Growth into a vertically integrated petroleum enterprise
- 1920s–1950s: Major refining infrastructure expansion, reportedly using asbestos-containing materials (ACMs) as industry standard
- 1950s–1970s: Continued maintenance, renovation, and expansion with widespread alleged ACM installations
- 1970s–1980s: Increased regulatory scrutiny following OSHA’s establishment in 1971; facility reportedly underwent substantial maintenance and remediation work
- 1986–present: Ongoing corporate presence, facility renovation, and documented asbestos abatement efforts
The Findlay complex encompassed far more than the refinery itself — corporate office buildings, pipeline terminals, storage tank farms, maintenance shops, and extensive heavy industrial infrastructure. Every one of these facility types historically relied on asbestos-containing materials.
Asbestos is a naturally occurring silicate mineral whose thermal and fire-resistant properties made it the default insulation choice throughout 20th-century industrial operations:
- Extreme heat resistance: Fibers withstand temperatures exceeding 1,000°F without burning or degrading
- Superior insulating properties: Reduced heat loss from pipes, boilers, and process equipment
- Fire resistance: Non-combustible; used to fireproof structural steel and mechanical systems
- Chemical inertness: Asbestos-containing gaskets and packing resisted degradation from petroleum products and harsh refinery chemicals
- Economic efficiency: Inexpensive, widely available, and long-lasting relative to competing materials
At a petroleum facility like Marathon’s Findlay operations, these properties drove ACM use into virtually every system. The need for heat management in high-temperature refining processes, constant movement of hot petroleum products through miles of piping, steam generation for process heating, and fire protection demands in a highly combustible environment all pushed plant managers toward asbestos-containing products.
General Equipment at Marathon Petroleum Findlay Ohio
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 Ohio Environmental Protection Agency (Ohio EPA) 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.

The materials documented above (and similar asbestos-containing materials commonly encountered in records of this type) appear in the AsbestosIndex catalog with historical manufacturer and trust-fund information. Click a category to view manufacturers historically associated with that material:
Who May Have Been Exposed at Marathon Petroleum Findlay Ohio
Insulation workers with Heat and Frost Insulators Local 1 (St. Louis) and Local 27 (Kansas City) who cut, shaped, fitted, and applied pipe insulation; Pipefitters with UA Local 562 (St. Louis) and Local 268 (Kansas City) working near insulated piping systems, routinely cutting compressed asbestos gasket sheet to fit flange dimensions and scraping old packing from valve stuffing boxes — tasks performed daily, often without any respiratory protection; Maintenance workers removing and replacing insulation during planned turnarounds and equipment overhauls, entering boiler shells for cleaning and inspection, overhauling and repairing pumps and rotating equipment, and replacing gaskets and seals; Boilermakers with the International Brotherhood of Boilermakers during installation, maintenance, repair, and inspection work on boiler systems and heat exchangers; Laborers handling, transporting, or disposing of insulation materials and debris; Plant operators and technicians working in boiler rooms and steam generation areas, handling valve packing and gasket materials during routine maintenance; Structural steel workers drilling, cutting, grinding, or welding near asbestos-containing fireproofing; Contract specialists brought in for major equipment overhauls during scheduled turnarounds and facility demolition or renovation projects; HVAC and mechanical contractors working near spray-applied fireproofing in confined spaces; Maintenance and custodial staff performing renovation, repair, or removal work on building materials; Electricians running conduit through floors or accessing structures.Critical Filing Deadline & Next Steps
Ohio law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (ORC § 2305.10). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (ORC § 2125.02). 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 Ohio 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.
