Asbestos is a naturally occurring, fibrous mineral found in the ground and mined all over the world. It is so small it can only be identified under a microscope. In the past, asbestos was added to various products such as insulation to increase fire resistant properties. Asbestos exposure, especially of an extended duration, has been linked to mesothelioma and other health problems, including lung cancer. Mesothelioma is a rare form of cancer that affects cells in the lining of the chest and abdomen. The tissues in these areas are called the mesothelium, and they produce a lubricating fluid that allows the organs to move easily and without irritation or injury in the torso cavity.

Asbestos fibers attach themselves to the lining of the lungs or other parts of the respiratory tract and remain there indefinitely. Asbestos is most dangerous when it is airborne. The fibers are small and light and can stay afloat for a long time and can travel great distances from their source. Since asbestos fibers are microscopic and airborne, people can breathe in asbestos fibers for many years without realizing it. Workers in environments in which construction materials, especially insulation, are handled are at greatest risk. Starting in the 1940s, workers, unaware of the danger, regularly handled and were exposed to large amounts of asbestos, often for long durations. Trades that involved especially high levels of exposure included asbestos production related fields like mining, milling, asbestos tile manufacture, and the manufacture of products that used asbestos. Other industries with high levels of possible exposure included shipbuilding, construction, car repair, and any form of demolition. Today, worker
