Historical Perspectives
Asbestos has been used since the late 1800s in commercial applications and the use increased greatly throughout World War II. Asbestos was used in military ships, vehicles and aircraft until the 1970s and many thousands of those who served in the military were exposed.
The Real History (and Danger!!) of Asbestos
Before experts knew that the inhalation of asbestos fibers caused several deadly diseases- including asbestosis, a progressive and often fatal lung disease, and lung and other cancers- asbestos was used in a large number of building materials and other products because of its strength, flame resistance, and insulating properties. Asbestos was used in asbestos-cement pipe and sheeting, floor and roofing felts, dry wall, floor tiles, spray on ceiling coatings, and packing materials.
Always presume building materials may contain asbestos. The U.S. has not banned asbestos entirely in all its forms, so employers must take caution when buildings, especially those built before 1980, are renovated or torn down. A commercial building or residence may still contain asbestos.
