Agent Name

Jet fuel

Major Category



JP-4 (MIL-T-5624-L-Amd.1; wide cut) or JP-7 ( MIL-T-38219A-Amd.2; kerosene, low volatility); [ATSDR Case Studies # 32]


Petroleum, Refined


JP-4 is "composed mainly of alkanes in the C4 to C16 range. JP-7 is produced by blending kerosenes;" [ATSDR Case Studies]


About 85% of the aviation fuel used by the military is JP-4. JP-4 contains about 22% n-hexane and less than 0.5% benzene. [ATSDR Case Studies # 32] "Jet propulsion fuel 8 (JP-8), a volatile lipophilic kerosene-based fuel, is the main jet fuel used by the US Air Force (USAF). Because of its higher flash point and lower acute toxicity, JP-8 completely replaced JP-4 by 1995." [Reference #1]


Both JP-4 and JP-7 contain n-hexane, and peripheral neuropathy has been reported in chronically exposed workers. About one half of workers exposed to 500 ppm report symptoms of acute solvent intoxication, i.e., headache and giddiness. An evaluation of 12 workers with such symptoms after cleaning jet fuel cells failed to find any abnormalities of liver function tests. [ATSDR Case Studies # 32] Aliphatic and aromatic hydrocarbons cause trivial hepatic injury in animal experiments. [Haddad, 226t] See "Kerosene."
