Because asbestos was commonly used in the shipbuilding industry, many workers and military servicemen, and women experienced high exposure to asbestos. Asbestos was widely regarded for its heat-resistant properties and ability to prevent fires. Shipyards on both coasts of the U.S. have long, storied histories of asbestos exposure, and an unfortunate legacy of former workers and service members developing asbestos-related diseases, including lung cancer, asbestosis, and mesothelioma, as a result of that exposure.
