Yes. In fact, the workers subjected to the highest levels of exposure to asbestos were the machine operators, since they were constantly interacting with asbestos-laden equipment. Some workers would apply spray-on asbestos insulation directly on machinery, while others would cut and use sandpaper on insulation.
Power plants are indispensable in our world. With the use of generators, power plants - also known as power stations or powerhouses - transform mechanical power into the electrical energy we cannot imagine living without nowadays. At the moment, there are over 50,000 power plants in the U.S. Electricity is generally produced by burning fossil fuels such as natural gas, coal or oil, although some plants use nuclear power or renewable sources of energy (for instance, solar or hydroelectric energy).
As the process of generating electricity involves extreme temperatures and the risk of fire, combustion and overheating is ever-present, asbestos was frequently used for insulating machinery and equipment in power plants between 1930 and 1980.
Power plants are enormous facilities and for this reason, their proper functioning usually requires over 400 employees. While machine operators supervise the power generating equipment and ensure it works efficiently, distributors control the rate at which electricity is produced, and dispatchers examine demands to determine how much electrical energy the facility needs to generate.
The most common asbestos-containing products in power plants include:
Boilers, generators, turbines, valves, pumps, and gaskets were only some of the machinery and components where asbestos was used as insulation or to reduce friction. By working on maintaining and repairing this equipment, operators would inevitably release tremendous amounts of toxic fibers in the air, which they would subsequently inhale.
In power plants, asbestos was often used as thermal insulation for equipment and piping.
Nuclear power plants use high-temperature reactors, which makes durable insulation materials like asbestos all the more attractive to make plants more efficient.
At first, you'd think the primary individuals at risk for asbestos exposure were insulation workers, and although they are at high risk, other power plant workers were similarly at risk of exposure:
Machine operators were another group of workers subjected to the highest risk of inhaling asbestos dust in power plants since they were constantly interacting with asbestos-laden equipment. Some workers would also apply spray-on asbestos insulation directly on machinery, while others would cut and use sandpaper on insulation, creating hazardous dust. Because power plants are facilities operating 24/7, the majority of employees would work twelve-hour shifts, thereby airborne asbestos fibers were inhaled for extended periods of time on a regular basis.
Distributors and dispatchers might have been exposed to the risk of inhalation of this carcinogenic mineral as well, as it was not unusual for the floors and roofs to be insulated with solid layers of asbestos. Poor ventilation, which was common in most power plants, only increased the duration of exposure.
Due to the astounding prevalence of asbestos use, nearly all power plants in the U.S. exposed their workers to this naturally occurring mineral throughout the past century. Our clients have worked in power plants across the country, including the following 43 states:
