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