Jet Fuel and Aviation Worker Exposure (JP-8 Kerosene, Benzene, Naphthalene, Flight Line Workers, Dermal Absorption, USAF Occupational Studies) — outdoor safety profile
High riskMilitary and civilian aviation workers handling jet fuel (JP-8/Jet A, kerosene-type fuel) face chronic occupational exposure to a complex hydrocarbon mixture containing benzene (0.02-0.5%), naphthalene (1-3%), and hundreds of other aromatic and aliphatic hydrocarbons.
What is this product?
Military and civilian aviation workers handling jet fuel (JP-8/Jet A, kerosene-type fuel) face chronic occupational exposure to a complex hydrocarbon mixture containing benzene (0.02-0.5%), naphthalene (1-3%), and hundreds of other aromatic and aliphatic hydrocarbons. USAF occupational health studies spanning 1995-2015 have documented that flight line fuel handlers have statistically significant elevated blood benzene levels compared to non-fuel-handling military personnel — with mean blood benzene 0.15-0.45 ng/mL in fuel handlers versus 0.05-0.10 ng/mL in controls (Smith et al., 2010, Ann Occup Hyg). Dermal absorption is a critical and often underappreciated exposure pathway: JP-8 rapidly defats the skin barrier, and naphthalene dermal absorption was demonstrated to contribute 50-70% of total body burden in fuel handlers by Chao et al. (2006, Ann Occup Hyg). Fuel tank entry operations represent the highest-exposure scenario — confined space with vapor concentrations of 50-300 ppm total hydrocarbons, requiring supplied-air respiratory protection and continuous atmosphere monitoring. The NIOSH REL for benzene is 0.1 ppm (10-hour TWA), while the OSHA PEL remains at 1 ppm (8-hour TWA) — NIOSH considers benzene a confirmed human carcinogen (leukemia) with no safe exposure threshold. A 2012 National Academies review of Gulf War illness included JP-8 exposure as a candidate causal factor for chronic multisymptom illness among veterans. Civilian aviation fuel handlers (airport tarmac workers) have similar exposure profiles but often less comprehensive occupational health monitoring than military counterparts.
