Why is Asbestos Hazardous?
The use of asbestos sharply declined in the late 1970s when it became evident that asbestos posed a threat to human health and safety. Today, asbestos is classified as a known human carcinogen. The property of durability—which made asbestos so desirable to manufacturers—is that which makes asbestos hazardous. Asbestos fibers are microscopic (roughly .02 the diameter of a human hair), and therefore, are easily inhaled. Once inhaled, the fibers cling to the respiratory system, including the lining of the lungs and inner cavity tissue. As asbestos fibers are typically quite rigid, they become lodged in the soft internal tissue of the respiratory system and are not easily expelled or broken-down by the body.
Hundreds of thousands of people were exposed to asbestos in some capacity as a result of the mineral’s extensive use in domestic, commercial, and industrial products. There is no safe type of asbestos and no safe level of exposure. Nearly all those with exposure history are potentially at risk of serious respiratory health complications.
