Ohio Asbestos Exposure Job Sites A-Z
Ohio, Asbestos Exposure and Mesothelioma Lawsuits
Ohio, known for its industrial heritage, has a significant history of asbestos exposure in various job sites across the state. Industries such as manufacturing, construction, mining, and automotive assembly utilized asbestos-containing materials extensively, putting workers at risk of exposure to harmful asbestos fibers.
Construction sites in Ohio often used asbestos-containing materials for insulation, roofing, and fireproofing. Similarly, manufacturing plants employed asbestos in machinery, equipment, and building materials. Workers in these industries, along with miners extracting minerals like asbestos and coal, faced significant exposure risks. Additionally, automotive workers handling brake pads and mechanics repairing vehicles may have encountered asbestos-containing parts.
Unfortunately, many Ohioans were exposed to asbestos without adequate protection or awareness of the health risks involved. As a result, individuals exposed to asbestos on job sites in Ohio are at an increased risk of developing asbestos-related diseases such as mesothelioma, lung cancer, and asbestosis.
Efforts to mitigate asbestos exposure in Ohio have led to stricter regulations and safety measures in recent decades. However, the legacy of past asbestos use continues to impact workers and communities throughout the state. For those affected by asbestos-related diseases, seeking legal assistance may be necessary to pursue compensation and hold accountable those responsible for their exposure on Ohio job sites. Experienced mesothelioma lawyers can provide guidance and support in navigating the legal process.
History of Asbestos Exposure in Ohio
Ohio’s industrial history has intertwined with widespread asbestos use, leading to significant exposure risks on job sites across the state. From the late 19th century through much of the 20th century, industries such as manufacturing, construction, mining, and automotive production relied heavily on asbestos-containing materials for their desirable properties like heat resistance and durability.
Construction sites throughout Ohio often used asbestos-containing materials for insulation, roofing, and fireproofing. Manufacturing facilities, prevalent in cities like Cleveland, Akron, and Toledo, utilized asbestos in machinery, equipment, and building materials. The automotive industry, particularly in cities like Dayton and Cincinnati, incorporated asbestos into brake pads, gaskets, and other components. Workers in these industries faced daily exposure to asbestos fibers during production, maintenance, and demolition activities.
Ohio’s mining industry, which extracted minerals such as asbestos and coal, also posed significant exposure risks to workers. Miners, along with those handling and processing mined materials, faced direct contact with asbestos fibers in the workplace. Asbestos exposure was pervasive across various job sites, contributing to the state’s industrial growth but also leading to a legacy of asbestos-related diseases among workers.
Despite increased awareness and regulatory measures in recent decades, the impact of past asbestos exposure continues to affect Ohio communities. Understanding the history of asbestos exposure on Ohio job sites is crucial for recognizing and addressing the health risks faced by workers and residents alike.
Asbestos Cover up – Quotes from Asbestos Executives
Evidence in thousands of court documents have shown that asbestos companies hid and destroyed memos, documents and ignored doctor’s medical reports about the dangers of asbestos exposure. Despite all the information about the deadly dangers of asbestos exposure available in the scientific and medical literature asbestos companies chose not to take any action to protect workers.
They chose profit over the safety of their workers and then lied and covered it up. This is why U. S. Courts are making asbestos manufacturers and companies pay millions to asbestos victims for their asbestos cover up.
- “…if you have enjoyed a good life while working with asbestos products, why not die from it.”1966 memo from an executive of the Bendix Corporation (now part of Honeywell)
- In early 1940s, the president of Johns-Manville called the managers of another company “a bunch of fools for notifying employees who had asbestosis.” When asked by another company executive, “Do you mean to tell me you would let them work until they drop dead?” he responded, “Yes. We save a lot of money that way.”

Ohio Mesothelioma Lawsuit Settlements
The value of your Mesothelioma lawsuit will depend on how many asbestos-containing products you were exposed to, the number of defendants (asbestos companies) available, your age, earning capacity and overall health. Mesothelioma cancers are clearly linked to asbestos exposure.
There is a long history of asbestos companies lying, deceiving, cheating and conspiring to conceal the dangers of asbestos exposure from their workers. It is a documented fact that many asbestos companies knowingly kept their workers in the dark and misled them about safety measures that could have prevented them from getting Mesothelioma and other asbestos-related diseases. A Mesothelioma diagnosis brings financial stress, loss of income, medical expenses, and treatments that may not covered by health insurance. Filing a Mesothelioma lawsuit can help with these added expenses.
