Pennsylvania Asbestos Exposure Job Sites
Pennsylvania Job Sites, Asbestos Exposure and Mesothelioma Lawsuits
In Pennsylvania, numerous job sites have been linked to asbestos exposure, putting workers at risk of developing mesothelioma and other asbestos-related diseases. Companies such as U.S. Steel in Pittsburgh, Bethlehem Steel in Bethlehem, and the Philadelphia Naval Shipyard have historically used asbestos in their operations, leading to exposure among workers.
Workers in industries such as steel manufacturing, shipbuilding, power generation, and construction were particularly vulnerable to asbestos exposure due to the widespread use of asbestos-containing materials in these sectors. Asbestos was commonly used for insulation, fireproofing, and other purposes in buildings, machinery, and equipment.
Unfortunately, many workers in Pennsylvania were unknowingly exposed to asbestos fibers, which can become airborne during activities such as cutting, sanding, or demolishing asbestos-containing materials. Inhalation or ingestion of these microscopic fibers can lead to serious health issues, including mesothelioma, lung cancer, and asbestosis.
As a result, many individuals in Pennsylvania have pursued mesothelioma lawsuits to seek compensation for their medical expenses, lost wages, and pain and suffering caused by asbestos exposure. Mesothelioma lawyers in Pennsylvania specialize in representing victims of asbestos exposure and advocating for their rights in legal proceedings. Raising awareness of the risks associated with asbestos exposure and ensuring access to legal recourse are essential for protecting the health and well-being of Pennsylvania workers.
History of Asbestos Exposure on Pennsylvania Job Sites
Pennsylvania has a significant history of asbestos exposure on its job sites, spanning various industries like shipbuilding, construction, manufacturing, and mining. Asbestos was widely used in these sectors due to its fire-resistant and insulating properties. Beginning in the early 20th century and continuing through much of the century, asbestos-containing materials were prevalent in buildings, machinery, equipment, and infrastructure across Pennsylvania.
Shipyards along the Delaware River, including those in Philadelphia and Pittsburgh, heavily relied on asbestos in ship construction and repair. Similarly, construction projects throughout the state, including the building of bridges, roads, and commercial buildings, utilized asbestos-containing materials. Additionally, the mining industry in regions like the Allegheny Mountains exposed workers to asbestos fibers, as asbestos was commonly found in minerals such as vermiculite.
Unfortunately, many workers in Pennsylvania were unaware of the dangers of asbestos exposure during this time. It wasn’t until later years that the harmful effects of asbestos became widely recognized, leading to increased regulations and safety measures. However, the legacy of asbestos exposure persists in Pennsylvania, with many individuals developing asbestos-related diseases such as mesothelioma, lung cancer, and asbestosis as a result of past exposure on job sites throughout the state. Efforts to raise awareness and implement stricter safety standards remain crucial for preventing future cases of asbestos-related diseases in Pennsylvania.
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.”

Pennsylvania 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.
