Key Takeaways
Air Force Veterans who worked on the flight line, in fuel cells, or around aircraft maintenance were routinely exposed to JP-4, JP-5, and JP-8 jet fuel, all of which contain benzene and other volatile chemicals tied to cancer, neurological damage, and heart disease. Because jet fuel exposure by itself is not automatically presumptive under the PACT Act, most of these claims still depend on medical evidence linking a current diagnosis to that exposure. Sean Kendall's legal team works with Air Force Veterans nationwide to build that evidence and pursue the benefits they are owed.

For decades, Air Force flight line crews, fuel cell technicians, and aircraft maintainers spent their shifts standing in fumes that smelled like a gas station on a hot day. Fuel soaked into gloves, coveralls, and boots. Ventilation on the flight line was whatever wind happened to be blowing that afternoon. Almost nobody wore a respirator. Decades later, some of those same Veterans are dealing with leukemia, chronic dizziness, or heart disease that traces back to that daily exposure, and many are surprised to learn that jet fuel is not automatically covered the way burn pit exposure often is.
The Law Office of Sean Kendall has spent decades litigating toxic exposure and other complex service-connection cases, representing Veterans of every branch before the Department of Veterans Affairs (VA) and the U.S. Court of Appeals for Veterans Claims. We help Veterans nationwide fight for the benefits they earned through service.
Here's what you should know about jet fuel exposure, the conditions it has been linked to, and what an Air Force Veteran needs to prove a claim.
What Jet Fuels Did Air Force Personnel Work Around?
The Air Force has used several kerosene-based fuels over the years, and each one carried its own mix of hazardous chemicals. JP-4 was the primary fuel through the early 1990s and was especially volatile, producing heavy vapor exposure for anyone nearby. Between 1992 and 1996, the Air Force largely transitioned to JP-8, a less volatile but still hazardous fuel that remains widely used today. JP-5, a similar kerosene-based fuel used mainly by the Navy, also shows up in some joint-service and shared-airfield assignments.
All three fuels are complex mixtures of more than 200 aliphatic and aromatic hydrocarbons, including benzene, toluene, ethylbenzene, xylene, and naphthalene. Fuel cell maintainers, who physically entered aircraft fuel tanks to inspect and repair them, often had the highest exposure levels, but flight line crews, refuelers, and even administrative personnel stationed near flight operations absorbed these chemicals through inhalation and skin contact.
What Health Conditions Have Been Linked to Jet Fuel and Benzene Exposure?
Because jet fuel is a chemical mixture rather than a single substance, its health effects show up across several body systems. Veterans filing a claim typically need to identify a specific, currently diagnosed condition rather than "jet fuel exposure" as a standalone disability.
Cancers and Blood Disorders
Benzene is a well-documented human carcinogen, and long-term exposure has been associated with leukemia and other blood cancers. Veterans researching benzene-linked disease may recognize some of the same conditions discussed in claims involving contaminated water exposure at Camp Lejeune, since benzene is one of the shared chemicals in both exposure scenarios.
Neurological and Balance Problems
Studies of Air Force fuel cell workers and flight line personnel have documented dizziness, headaches, fatigue, and vestibular dysfunction, sometimes described as chronic imbalance, following repeated jet fuel exposure. Some research also points to changes in reaction time and neuropsychological test performance among Veterans with cumulative exposure.
Heart and Respiratory Effects
Long-term exposure to jet fuel components has also been connected to cardiovascular problems, including hypertension and coronary artery disease, along with respiratory irritation from repeated vapor inhalation.
Does the PACT Act Cover Jet Fuel Exposure Claims?
Many Veterans assume that because the PACT Act expanded coverage for toxic exposure claims tied to burn pits and Agent Orange, jet fuel exposure must be covered the same way. It usually is not. PACT Act presumptions apply to Veterans who served in specific locations during specific time periods and later developed a condition on the VA's presumptive list, most of which trace back to burn pits and airborne hazards rather than fuel handling on a domestic flight line. Our overview of the most commonly filed PACT Act claims and our explanation of presumptive respiratory conditions under the PACT Act both cover conditions that may overlap with a jet fuel case, but a Veteran whose only exposure was stateside fuel handling generally still needs to prove a direct service connection.
According to the Department of Veterans Affairs, a presumptive condition means the VA assumes military service caused the disability once a Veteran meets the service and diagnosis requirements, without needing separate proof of causation. Jet fuel exposure claims that fall outside that presumptive framework require the Veteran to independently establish the connection between service and their current condition.
How Do You Prove a Direct Service Connection for Jet Fuel Exposure?
A direct-connection claim generally needs three things: a current diagnosis, evidence of an in-service exposure event or duty, and a medical opinion connecting the two. For jet fuel cases, that evidence often includes:
-
Military occupational specialty codes showing fuel-related duties, such as aerospace propulsion, fuel systems maintenance, or flight line crew assignments
-
Duty station records confirming time spent near active flight operations or fuel cell maintenance bays
-
Buddy statements from fellow service members describing the working conditions, protective equipment (or the lack of it), and how often exposure occurred
-
A nexus letter, written by a qualified medical provider, explaining why the Veteran's current condition is at least as likely as not connected to jet fuel exposure during service
Veterans whose jet fuel-related conditions leave them unable to keep steady work should also look into unemployability claims for Veterans, since combined disabilities from multiple body systems can sometimes qualify for compensation at the 100 percent rate even when no single condition reaches that level on its own.
What Should You Do if You Believe Jet Fuel Exposure Affected Your Health?
Start by gathering your service records, especially anything that shows your military occupational specialty, duty stations, and time spent near the flight line or fuel cell operations. Ask your doctor to document your diagnosis clearly, and hold onto any earlier medical records that show when your symptoms began. Because direct-connection claims depend heavily on medical evidence rather than a location-and-date presumption, the strength of your nexus evidence often determines whether your claim succeeds on the first attempt or ends up in a lengthy appeal.
