Johns Manville was one of the first major companies to use asbestos in its products. From the late 1800s through the 1900s, Johns Manville employees were exposed to asbestos through a number of materials. In the mid-1970s, Johns Manville was still one of the leading U.S. manufacturers of asbestos-containing construction materials. Shortly thereafter, the company began phasing out the use of asbestos and all asbestos products were eliminated by 1985. During the creation, installation or removal of these products, asbestos exposure is a serious hazard. Inhaling airborne asbestos fibers is known to cause mesotheliom, lung cancer and asbestosis. While symptoms do not immediately arise, exposed workers should understand the potential of developing one of these conditions in the future.
