Asbestos contains microscopic fibers that, when released into the air, can be breathed into the lungs, where they can remain for several years before serious health issues become apparent. Exposure to these fibers can cause serious health issues, including cancers like mesothelioma. Insulation was the largest source of exposure to asbestos for workers throughout the 1900s.
Insulation Use
Insulation provides many benefits, including energy conservation, sound deadening, reduction of electrical conductivity, and help with the retention of hot and cold temperatures. Asbestos was particularly well-suited for these purposes, as it is fire resistant and a poor conductor of electricity. In addition, it was cheap and durable. The use of asbestos in insulation products began in the late 1800s to help protect against high-temperature pipes. By 1874, asbestos insulation products were commercially produced and sold on a large-scale basis.
