In 1964, at the request of the Federal Aviation Agency, an Ad Hoc Group on Aviation Fuel Safety was organized by the Coordinating Research Council, Inc. This Group assembled and reviewed the technical information available concerning the safe handling and usage of aviation gasolines, jet A (kerosene), and jet B (JP-4), which are currently used as commercial aviation fuels. After reviewing the available information, the consensus of the Ad Hoc Group was that, while there are differences among the fuels, adoption of a single type of aviation turbine fuel by the entire industry would not significantly improve the overall excellent safety record of commercial aviation, and that safety is more a function of equipment design, proper handling techniques, and rigorous precautions than of the particular fuel type employed.
