Studies show that even the slightest exposure to asbestos can be harmful; however, individuals exposed to high levels of asbestos on a day to day basis for long periods of time are at the highest risk of developing an asbestos-related illness such as mesothelioma, lung cancer or asbestosis. This puts individuals that work directly with asbestos at the highest risk.
Toxic Fibers
Asbestos in its natural state is not harmful. It is when the fibers separate due to damage or decay that they become toxic. The fibers are microscopic so they are easily inhaled. Once the fibers are inhaled, they can become embedded in the heart, stomach or most commonly, the lungs.
Over time, the asbestos fibers accumulate and can cause severe irritation and may eventually lead to the development of a deadly disease.
Mid-Century Exposure
It wasn't until the late 1970s that the effects of asbestos became widely known. Asbestos use peaked from the 1950s to 1975 in industrial, maritime, automotive and building products because of its durability and resistance to heat and friction. Many individuals working in those industries were exposed to extremely hazardous levels of the toxic fibers and are now suffering from its effects. Following is a list of high-risk occupations:
Even though asbestos use has been strictly regulated since the discovery of its harmful health effects, there are still high-risk occupations. For instance, there are still many older homes that were built before 1975 that contain asbestos. As the material decays and the asbestos break down, the fibers separate and can be released into the air. This creates a danger for demolition workers who are sent in to tear down or replace the damaged material.
The same is true for shipyard workers who repair and replace asbestos-containing materials on older vessels and for mechanics working on older cars that may have asbestos woven into the thermal insulation or the internal lining of fume hoods and exhaust ducts.
As an answer to asbestos exposure, federal and state governments have established laws and regulations surrounding workplace exposure to ensure the safety of any individuals who may work in high-risk occupations. For more information on the laws surrounding high-risk occupations, please contact us .
