A 1935 report by the Pennsylvania Department of Labor highlighting the type and quantity of asbestos dust to which workers may be exposed during their work in a factory and the effects of asbestos exposure on these individuals. Among the reports findings were that 25% of workers studied had symptoms of an asbestos-related disease. Exposure to asbestos may result in a number of serious and potentially fatal illnesses, including mesothelioma, lung cancer, and asbestosis. Despite the health risks associated with asbestos, the United States has yet to institute a complete ban on the use of asbestos products.
