Contributing Factors
Although Oklahoma has no natural asbestos deposits, exposure has occurred through industrial and occupational settings. Agriculture, oil, and natural gas industries have long been central to the state's economy and are among the most significant sources of asbestos exposure.
Workers in these industries frequently encountered asbestos in equipment, insulation, and industrial facilities where the mineral was used for its heat-resistant properties. Counties along Oklahoma's southern border show slightly higher mesothelioma mortality rates, suggesting localized exposure risks.
Power plants and military installations also historically relied on asbestos-containing materials. Additionally, the Environmental Protection Agency has identified more than a dozen Superfund sites in Oklahoma, many associated with oil and gas operations that required asbestos-related cleanup.

High-Risk Occupations for Asbestos Exposure in Oklahoma
While Oklahoma is widely known for agriculture, it also ranks among the top states for oil and natural gas production. This industrial history has placed many workers at increased risk for asbestos-related diseases.
Industrial Workers
Oklahoma's manufacturing sector employs thousands, particularly in tire production and oil and gas equipment manufacturing. Many of these facilities historically exposed workers to asbestos. Tulsa's airline maintenance operations also used asbestos-containing products such as brakes, insulation, valves, and gaskets.
Oil Refinery Workers
Asbestos exposure was widespread in Oklahoma's oil industry. Companies such as Sun Oil and Phillips Petroleum exposed workers at multiple sites, including the former Oklahoma Refining Company in Cyril, now listed as an EPA Superfund site.
Power Plant Workers
Many Oklahoma power plants relied on asbestos insulation during electricity and heat generation. Facilities such as Garson Light & Power Company, Oklahoma Gas and Electric Company, and the Ponca City Municipal Electric System exposed workers to airborne asbestos fibers for decades.
Naval and Military Veterans
Asbestos was widely used in military aircraft, ships, vehicles, and base infrastructure. In Oklahoma, major installations such as Tinker Air Force Base, the Naval Ammunition Depot in McAlester, and Fort Sill exposed service members, civilian employees, and even family members to asbestos. Muskogee's Veterans Hospital also contained asbestos materials for many years.
Landmark Oklahoma Asbestos Verdict
Family of Brennen James Atkeson vs. Various Defendants
Brennen James Atkeson was exposed to raw asbestos as a child through products manufactured and distributed by Union Carbide Corporation and Montello Inc., as well as asbestos-containing drilling rig products made by National Oilwell.
He inhaled asbestos fibers brought home on the clothing of his stepfather, Ronnie Pratt, an oil field worker. Brennen was later diagnosed with mesothelioma and passed away in 2016 at the age of 38.
In May 2019, a Pontotoc County jury found the defendants liable for failing to warn workers about the dangers of their asbestos-containing products. The Oklahoma Court of Civil Appeals upheld an $8 million verdict awarded to Brennen's estate.
