Asbestos Exposure: Who Is At Risk?
Wednesday, August 3rd, 2011It is quite possible that virtually everyone will be exposed to asbestos at some point in their lifetime. Even if a person never encountered asbestos-containing materials, asbestos is present in our environment in very low levels. Nonetheless, most people will not develop an asbestos-related disease from this kind of exposure.
According to the National Cancer Institute, certain people are at a much higher risk for asbestos exposure and therefore asbestos-related diseases, such as asbestosis and mesothelioma. These diseases pose a greater threat to people who encounter asbestos regularly or who are exposed to extreme levels, such as the rescue workers and volunteers helping in the aftermath of September 11, 2001. The collapse of the World Trade Center North Tower released several tons of asbestos into the air, potentially affecting thousands at the site and surrounding areas. This, of course, is an extreme example of acute environmental exposure. Most cases of asbestos-related disease are linked to certain industries affected by mesothelioma.
Because the risk of exposure often does not surface until many years later, the current list of high-risk jobs is different than those of the past. Obviously, workers who mine asbestos or mesothelioma linked materials that may be contaminated with asbestos are at a great risk, as well as those who work in asbestos product manufacturing.
Additionally, workers involved in the construction business are at a higher risk of ongoing exposure to asbestos-containing materials in older homes. Activities involving demolition, wall removal, popcorn ceiling removal and work in the attic, can bring a worker in contact with asbestos-containing materials. Firefighters exposed to demolished homes may also run a high risk for repeated exposure. Auto-mechanics involved with brake repair can be at risk for asbestos contact. Some studies have shown that family members of these workers can also be affected, as their loved ones bring asbestos fibers into the home on their clothes. Proximity to asbestos mines may also be a factor. There have been cases of people living near mines developing asbestos-related diseases when they had no other known source of exposure.
Government regulations have come a long way in protecting workers’ health against asbestos exposure. Yet, the potential for exposure is still very real, and the degree to which proper safety precautions are followed on the job may make all the difference in the frequency and severity of the exposure.
Certain factors can affect one’s risk of developing an asbestos-related illness. Studies have indicated that the effects of smoking and asbestos exposure combined may be far more deadly than they are separately. Also, the type of fiber, dose, duration and individual health may alter a person’s risk of developing these diseases.
