Free Asbestos Testing

Ohio Asbestos Jobsites

Before asbestos was banned in the 1970s, thousands of workers in Cleveland, Columbus, Cincinnati, Toledo, Akron, Dayton or other cities may have been exposed to asbestos at jobsites in these cities.

Workers at oil refineries, power plants, trains and railroads, chemical plants, steel mills, shipyards and other jobsites where asbestos products were used in the state of Ohio may be at risk of developing mesothelioma cancer, lung cancer or other asbestos-related diseases. Veterans of the U.S. Navy, Merchant Marines, or other military branches may also be at risk of illness from asbestos materials that were used by the armed forces.

Because of the long latency period for asbestos-related diseases, workers who were exposed decades ago may only now begin to show the first symptoms of mesothelioma, lung cancer, or other illnesses caused by asbestos.

If you or someone you love may have been exposed to asbestos at one of the following jobsites, you may be eligible to receive a free health examination to find out whether you have develop symptoms of mesothelioma or other asbestos illnesses. For more information about how to receive free asbestos testing, contact the attorneys at Hissey Mulderig & Friend by calling toll-free at 1-855-500-3734, or by filling out the free case evaluation form located in the upper left corner of this page.
