Oil refineries are industrial plants where crude oil, the unprocessed oil that comes out of the ground that is also known as petroleum, is processed and refined into various useful products, including gasoline, heating oil, kerosene and diesel. The process of refining oil requires the thick liquid to be boiled, allowing gases to be released and allowing various chemicals to be separated. Oil refineries are typically large complexes with extensive piping to transport fluids between large chemical processing units.
There are several refinery specialties identified by professional societies, including millwrights and welders, pipefitters, boiler makers, electricians and engineers. In a country dependent on petroleum, oil refinery workers perform vital, but dangerous jobs. Petroleum is highly flammable and can cause explosions and damaging fires that may even claim lives. Oil refinery workers may operate or control refining or processing units, maintain and repair equipment, control pumping systems, gauge or test oil in storage tanks or regulate the flow of oil into pipelines.
As of Jan. 1, 2012, there were a total of 144 operable petroleum refineries in the United States, and as of May 2011, there were approximately 41,570 employed oil refinery workers in the nation. Also in May 2011, Texas held the highest employment rate in this occupation with an estimated 21,760 employees.
In addition to the risks of explosions and fires, oil refinery workers risk exposure to asbestos. Prior to changes in federal law, asbestos was commonly used to insulate equipment that operates at the high temperatures common at these facilities.

Regardless of their specific occupation, oil refinery workers’ exposure to asbestos was usually the result of directly handling equipment, involvement in the process of refining crude oil, the use of protective clothing or from inhaling fibers released from damaged material.
Refining oil requires the oil to be boiled, which releases gases and allows for chemicals to separate. It is this boiling that explains the use of asbestos: Parts, equipment and protective gear need to be insulated. Not only can asbestos reduce the risk of fire and prevent burns, but it also is resistant to chemical reactions.
Asbestos was primarily used in areas where heat and fire were a concern. Many of the processes taking place inside the work space of these facilities required employees to cut, sand and handle asbestos-containing materials, which created asbestos dust. These tiny asbestos fibers were easily made airborne where they could linger for oil refinery workers to inhale and ingest. Once these fibers are inhaled, most are expelled, but some can become lodged in organ tissues and remain there throughout life. The accumulation of fibers can cause inflammation and scarring that may lead to the development of mesothelioma cancer and other asbestos-related illnesses.
Asbestos was also commonly used in clothing, usually worn by oil workers as protection against heat and the risk of potential fires. Such protective clothing included aprons, gloves, shoe covers, pants and facemasks. If damage occurred to these items, fibers were released and potentially inhaled. This brought especially high risks for those who wore asbestos face masks. The material, similar to that used within the pipes, contained asbestos fibers and would also decompose over time and circulate in the work area.
A study conducted in 2000 by researchers of the National Cancer Institute titled ‘Mesothelioma and Lung Tumors Attributable to Asbestos Among Petroleum Workers’ found 96 to 100 percent of mesothelioma cases, and 42 to 49 percent of lung cancer cases among oil refinery maintenance workers, were attributed to asbestos exposure. The same study also found two cases of asbestos-related lung cancer among these workers for each case of mesothelioma.
A British study of more than 45,000 oil refinery workers employed in the industry for at least a year between 1946 and 1971, found significantly elevated rates of mesothelioma and other asbestos-related diseases.
Ginger Hall, the wife of a refinery worker, filed an asbestos cancer lawsuit on June 25, 2012 against 11 companies where her husband worked, including Chevron USA, Citgo, DuPont, ExxonMobil, Huntsman Petrochemical, Mobil Chemical, Mobil Oil, Oxy USA, Texaco, Union Oil, and Unocal Corp.
According to her asbestos lawsuit, Hall was exposed to asbestos through her husband’s employment at several area refineries because he would come home with asbestos dust on his clothing. After years of exposure to secondhand asbestos, Hall began to suffer breathing difficulties and eventually developed cancer. Hall is now seeking exemplary damages, past and future medical expenses, mental anguish, pain, impairment and lost wages, plus all court costs.
Amanollah Shahabi, a 76-year-old Iranian-American engineer, worked for the National Iranian Oil Company in Iran before relocating to the United States in the 1980s, where he worked as a consultant while obtaining his citizenship. He later worked for Bechtel on site at the Chevron refinery in Segundo, California.
For more than 40 years, Shahabi was exposed to asbestos found in oil refineries. In June 2007, Shahabi was diagnosed with mesothelioma, a terminal cancer caused by asbestos exposure, and he filed a lawsuit against A.W. Chesterton Company. In 2008, after a trial lasting more than a month, the jury awarded Shahabi $14.8 million.
The following companies have been defendants in asbestos and mesothelioma lawsuits.
