Many people throughout the world were exposed to asbestos and worked around asbestos without ever worrying about getting mesothelioma. This is due to the fact that no one knew the health risks that asbestos can cause just by being exposed to this natural mineral. This is why there were literally millions of people that inhaled asbestos dust between the 1850s and 1950s. Many construction workers and electricians would work with asbestos and inhale the dust particles and fibers without realizing that this could be dangerous to their health.The main types of workers that were affected by asbestos exposure included those that worked inside construction warehouses or in asbestos mines. With many people working these types jobs between the 1850s and 1950s, it is no surprise that mesothelioma was able to spread and be such a common disease. The other job fields that had exposure to asbestos included jobs such as electricians, roofers, and any other people who assisted in the construction of homes or buildings where asbestos was used. Even those people who later worked in these buildings had some risk of exposure to asbestos. Furthermore, the families of workers were also at a great risk of catching mesothelioma because of the asbestos fibers and particles.
