Jet Fuel (JP-8 / JP-5 / JP-4) Exposure

What is in military jet fuel

JP-8 is the U.S. military's primary jet and ground-vehicle fuel since the late 1980s. Its predecessors JP-4 (used through the 1990s) and JP-5 (still used aboard Navy ships and carriers for fire-safety reasons) share most of the same hazardous constituents.

All three fuels contain benzene, toluene, ethylbenzene, xylene (BTEX), naphthalene, polycyclic aromatic hydrocarbons (PAHs), and a long list of additives. Benzene is a recognized Group 1 human carcinogen by IARC; chronic exposure is linked to leukemia and myelodysplastic syndromes. Naphthalene and the PAHs are listed by NIOSH and EPA as probable human carcinogens.

High-exposure occupational groups

• Aircraft fuel-system mechanics and POL (Petroleum, Oils & Lubricants) specialists — Air Force AFSC 2F0X1, Army MOS 92F, Navy AB rate.
• Flight-line crew, aircraft maintainers, plane captains, and aerial-refueling boom operators.
• Aircrew (pilots, loadmasters, flight engineers) with chronic cabin-vapor exposure on transport and tanker aircraft.
• Naval aviation personnel exposed to JP-5 aboard carriers and amphibious assault ships.
• Fuels lab technicians and bulk-fuel storage personnel.
• Anyone who used JP-8 as a tent-stove or generator fuel in deployed environments — extremely common in OIF/OEF.

How jet fuel exposure claims are evaluated

There are two pathways depending on where you served:

1. PACT Act presumption — if your jet-fuel exposure occurred during a deployment to a covered Southwest Asia or post-9/11 location, jet fuel is recognized as a contributing airborne hazard. The covered conditions in the PACT Act presumptive list (cancers, respiratory diseases) apply automatically; you do not need to isolate jet fuel from burn pits or sand or diesel exhaust.
2. Direct service-connection — for stateside-only or non-covered exposure, you must document the occupational exposure (MOS, duty stations, fuel-handling certifications, training records) and obtain a medical nexus opinion linking your diagnosis to chronic hydrocarbon exposure.

Diagnoses commonly associated with chronic jet-fuel exposure

• Hematologic — acute and chronic leukemia, myelodysplastic syndromes, multiple myeloma.
• Solid tumors — bladder cancer, kidney cancer, lung cancer.
• Respiratory — chronic bronchitis, asthma, reactive airways dysfunction syndrome (RADS).
• Neurological — peripheral neuropathy, balance and cognitive symptoms reported in chronic POL workers.
• Skin — chronic dermatitis from dermal exposure.

Where these claims break down

• ×Filing only as 'burn pit exposure' when jet fuel is the actual primary exposure — the broader PACT Act framework still applies, but the medical nexus narrative is stronger when fuel exposure is documented.
• ×Not pulling your full personnel record to document POL training certifications and handling assignments.
• ×Skipping a private medical-nexus opinion when the case rests on direct service-connection rather than a presumption.
• ×Overlooking JP-5 exposure for Navy aviation personnel — JP-5 is chemically similar to JP-8 and is covered by the same scientific basis.
