Free Asbestos Testing

Pennsylvania Asbestos Jobsites

Individuals from the state of Pennsylvania who have been exposed to asbestos at home, work or in other locations may be qualified to bring a case against those who were responsible for causing this exposure. Discussing your history of asbestos exposure with an attorney is the first step in ensuring that your legal rights are safeguarded under the law.

Employees of asbestos jobsites in Philadelphia, Pittsburgh, Allentown, Erie, Reading and other cities and towns in the state of Pennsylvania may have been exposed to asbestos products used on the job. Veterans of the Navy, Merchant Marines or other service branches may also havebeen exposed to asbestos that was used onboard ships or in other materials used by the military.

Because it can take up to 50 years after exposure before an individual shows the first signs of an asbestos-related disease, it can be difficult to establish the products which were responsible for causing an individual’s asbestos exposure. An experienced mesothelioma attorney can assist you in identifying the products to which you may have been exposed.

If you or a loved one were exposed to asbestos and diagnosed with mesothelioma, lung cancer or other asbestos diseases, contact the lawyers at Hissey Mulderig & Friend to learn more about your rights. You can reach us by calling toll-free at 1-866-863-3848, or by filling out the free case evaluation form on the right of this page.

Pennsylvania Asbestos Jobsites by City

Pennsylvania contains thousands of jobsites—including shipyards, metal works, oil refineries, railyards—where asbestos exposure may have occurred.
