Located in Oklahoma City, Oklahoma, construction began in 1941, and the base became operational as the Oklahoma City Air Depot before being renamed to honor Major General Clarence L. Tinker, the first Native American major general in the U.S. Army Air Forces. Unlike many operational flying bases, Tinker functions primarily as an industrial center, home to the Oklahoma City Air Logistics Complex, the Air Force Sustainment Center, and Navy Strategic Communications Wing ONE, performing depot-level maintenance on aircraft like the B-52 Stratofortress, KC-135 Stratotanker, and E-3 Sentry. Decades of that mission required massive aircraft maintenance hangars, engine overhaul facilities, industrial manufacturing shops, and boiler plants, much of it constructed between the 1940s and 1960s.
AFFF exposure at Tinker Air Force Base
As a major Air Force aviation installation, Tinker maintained dedicated Aircraft Rescue and Firefighting capabilities to protect its aircraft maintenance operations and flight line activities. Historical environmental restoration documents identify Fire Training Areas tied to firefighter training at the base, including a site designated Fire Training Area #4, or FT024, investigated as part of the Installation Restoration Program after historical records suggested it may have served this purpose. That specific location was later determined not to have operated as a fire training area, but its inclusion in the restoration program shows how thoroughly the Air Force reviewed historical training locations at the installation, and Tinker maintains an active environmental restoration program addressing former operational and training sites.
Firefighter training at Tinker followed a routine familiar across Air Force installations of this era:
- fuel was ignited to simulate an aircraft emergency
- AFFF was applied to bring the fire under control
- proportioning systems were tested to confirm the mix
- vehicles and equipment were cleaned once the exercise ended
- foam supplies were restocked before the next round of training
Air Force Fire Protection Specialists and Aircraft Rescue and Firefighting personnel carried the bulk of this exposure, joined by fire instructors, firefighter trainees, fire apparatus operators, and the staff who maintained foam systems and firefighting vehicles.
The epidemiological data on firefighter PFAS exposure keeps surfacing the same two cancer types as statistical outliers. That's the population Tinker Air Force Base firefighters who trained regularly with AFFF belong to:
If your firefighter service there included this kind of training and you've since received one of these diagnoses, our team can review your history and let you know whether you're eligible to file an AFFF claim.
Asbestos exposure at Tinker Air Force Base
As one of the Air Force's largest industrial depots, Tinker relied heavily on asbestos for its heat resistance, durability, and insulating properties, and the base continues to maintain a formal asbestos management program today, reflecting how much of it remains in the installation's aging infrastructure. Materials commonly used throughout its hangars, engine overhaul shops, and boiler plants included:
Working in an industrial depot the size of Tinker Air Force Base meant constant contact with aging mechanical systems, hangar structures, and utility infrastructure. That kind of work fell to a specific set of trades:
Because Tinker has served as one of the Air Force's primary maintenance depots since World War II, thousands of personnel worked in industrial buildings where asbestos insulation, steam systems, boilers, and mechanical equipment were common, and aircraft maintenance facilities, utility plants, and industrial shops presented the greatest opportunities for exposure. Mesothelioma and lung cancer, the two conditions most closely tied to this kind of work, often don't surface for 20 to 50 years after the original exposure, meaning a veteran who served at Tinker Air Force Base decades ago might only be experiencing symptoms now. If your service included that kind of maintenance work and you've since received either diagnosis, contact our team to find out whether you're eligible to file an asbestos claim.
