Occupational asbestos exposure is the No. 1 cause of mesothelioma cancer. Repeated exposure to asbestos on the job puts workers at risk of several cancers and serious pulmonary diseases. Learn more about the occupations and industries that place people at risk of asbestos exposure.
Asbestos was used virtually everywhere in America. It is a mineral that exists naturally in a fibrous form and is resistant to heat, water, chemicals and electricity.
Throughout the 20th century, asbestos was incorporated into thousands of construction, commercial and household products.
These products include fireproof coatings, concrete and cement, bricks, pipes, gaskets, insulation, drywall, flooring, roofing, joint compound, paints and sealants. Asbestos also exists in electrical appliances, plastics, rubber, mattresses, flowerpots, lawn furniture, hats and gloves.
Working with asbestos products puts your health at risk. Asbestos exposure is proven to cause cancer and other serious diseases.
According to the Agency for Toxic Substances & Disease Registry, an estimated 27 million workers were exposed to asbestos between 1940 and 1979. Regulations have reduced the risk of exposure in the workplace, but a degree of risk remains for many occupations.
According to National Institute for Occupational Safety and Health, exposures to asbestos above the recommended limit declined from 6.3 percent of workers from 1987 to 1994 to 4.3 percent in 2000 to 2003.

The Occupational Safety and Health Administration (OSHA) didn’t regulate asbestos exposure in the workplace until 1971. Throughout the 1980s and 1990s, OSHA progressively reduced permissible asbestos concentrations in the workplace.
These measures helped limit the risk of workers developing related diseases. But, the consequences of poor regulation are still lingering because it takes decades for asbestos-related diseases to develop, which is known as the latency period.
Asbestos is still found across the country in buildings, roads, homes, schools, factories, ships, trains and automobiles. It’s regulated in the U.S., but it is not banned.
A surprising number of products are still made with asbestos, including automobile brakes and clutches, roofing materials and several other construction products.

Workers in high-risk jobs tend to handle asbestos in high concentrations on a regular basis.
Mining is the profession with the greatest potential for dangerous asbestos exposure. Mining for asbestos in the U.S. ended in 2002, but many miners have been exposed since then because certain minerals — such as talc and vermiculite — are contaminated with asbestos. Additionally, the equipment miners use contains asbestos insulation and asbestos gaskets.
The most notorious incident occurred in W.R. Grace and Co.’s vermiculite mine in Libby, Montana. Hundreds of vermiculite miners and their families died of asbestosis and mesothelioma in Libby. The R.T. Vanderbilt talc mines in upstate New York are other examples. These mines had dangerous levels of tremolite asbestos interlaced with the extracted minerals.
Construction jobs are a major source of asbestos exposure in the U.S. About 25 percent of people who die of asbestosis worked in the construction industry, according to the National Institute for Occupational Safety and Health.
Moderate-risk jobs involve direct or indirect work with asbestos materials. The concentration of asbestos fibers can range from low to high and may vary by day and jobsite.
Some jobs in this category expose workers to low levels of the mineral, but the frequency is enough for workers to inhale or ingest harmful amounts of asbestos over time. Other jobs may infrequently expose workers to high levels of asbestos.
Low-risk jobs infrequently place workers at risk of asbestos exposure. The concentration of toxic fibers in the workplace may be low or moderate. It may spike if a more dangerous project, jobsite or product is encountered. Even low-level asbestos concentrations can cause mesothelioma if exposure occurs regularly for years.

Asbestos was commonly used in the building of Navy ships throughout most of the last century. A large number of Navy veterans were exposed to the carcinogen as shipbuilders or sailors.
In fact, all divisions of the U.S. armed forces used asbestos in the construction of buildings, aircraft and automobiles.
In June 1999, the Navy Public Works Center (PWC) Lead and Asbestos Abatement Team began reducing the presence of lead and asbestos in shipyards using ice blasting technology.
This technique is favored in the cleaning of historic structures. It decreases the amount of hazardous waste produced and minimizes dust.
Asbestos remediation and decontamination also places workers at risk of exposure. Older buildings have asbestos in their walls, floors, attics, ceilings and roofs. When these buildings are torn down, exposure becomes a risk. Demolition crews, bulldozer and crane operators and other laborers can become exposed to asbestos dust.
Mechanics and operators of Linotype machines used in large-scale printing operations are at risk of asbestos exposure. Workers in several unlikely occupations, such as baking and painting, also were at risk of exposure.
OSHA enacted laws in 1997 that further limited the level of asbestos to 0.1 fibers per cubic centimeter at any jobsite. Employers are required to provide safe working conditions. They’re also required to provide protective clothing and equipment to employees who work around asbestos.
You can file a report if you suspect an employer isn’t providing safe conditions to protect workers from asbestos exposure. File a complaint with OSHA by calling or visiting a local OSHA office.
Workers who develop mesothelioma or any other asbestos-related disease may be eligible for compensation.
Compensation is sought from asbestos manufacturers who made asbestos products. These manufacturers are held liable for the diseases their asbestos products caused. Some of the manufacturers have set up asbestos trust funds, while others handle legal claims through settlements or trials.
Workers who develop an asbestos-related illness should find an experienced mesothelioma lawyer to guide them through the legal process.
