OSHA and Modern Asbestos Regulations

The use of asbestos for relatively modern industrial purposes dates back over a century, though partial knowledge of its dangers has existed for thousands of years. Despite concerns raised by medical doctors and scientists in the early 20th century, the asbestos industry avoided serious regulation for decades. Though laws like the Clean Air Act of 1970 did help reduce the use of asbestos , obstacles to stricter regulation were present as late as the 1990s, when an appeals court struck down an Environmental Protection Agency (EPA) regulation known as the Asbestos Ban and Phase Out rule. As a result, asbestos-containing products are used and produced even today.

Today, asbestos use and exposure is regulated by several government agencies, including the EPA and the Occupational Safety and Health Administration, otherwise known as OSHA.

Though virtually anyone can be exposed to asbestos, workers in industries such as construction, mining, and shipbuilding are particularly at risk. Furthermore, the families of these workers are also at risk from secondary exposure if precautionary measures are not taken.

According to OSHA, steps which can be taken to prevent excessive exposure to asbestos-containing materials (ACMs) include:

- Limiting the time that workers spend working with or around ACMs

- Separating asbestos-heavy areas from the majority of the workforce

- Installing effective ventilation systems in and around ACMs

- Providing workers with approved protective gear and clothing

- Providing workers with showers to remove asbestos after work

- Educating workers and administrators about the dangers of ACMs

Asbestos and Mesothelioma

Exposure to asbestos, even in small amounts and over a short period of time, can cause a deadly cancer known as mesothelioma. Mesothelioma is a cancer which attacks the mesothelial lining of the lungs, heart, chest, and abdominal cavity, and it is almost always associated with ACMs. In some cases, mesothelioma can take years to show up after exposure to asbestos, but can often kill within 6-12 months of diagnosis.

Though OSHA has set a limit of 100,000 fibers per cubic meter of workplace air, some experts contend that there is no such thing as a "safe" threshold of exposure, and advocate that the United States follow the example of other countries that have banned the use of asbestos entirely.
