摘要: Jet fuel and benzene vapor exposures were measured during aircraft tank entry repair at twelve U.S. Air Force bases. Breathing zone samples collected on the workers who performed repair. In addition, instantaneous taken various points procedures with SUMMA canisters subsequent analysis by mass spectrometry. The highest eight-hour time-weighted average (TWA) exposure found was 1304 mg/m3; 15-minute short-term 10,295 mg/m3. results indicate tanks containing explosion suppression foam have a significantly higher to jet as compared without (p < 0.001). It is assumed these elevations result from tendency for fuel, absorbed foam, volatilize removal process. Fuel that allow flow-through ventilation resulted in lower those only one access port and, result, cannot be...
