Among the many physical-chemical properties that a fuel needs to meet to be used, the flash point (FP) is a property that is intimately connected to the volatility of flammable liquids or fuels. It is the temperature at which the liquid vapor pressure is sufficient to produce a flammable mixture with the air . The FP, due to its relationship to liquid flammability, is an important factor in developing safe handling and storage practices for fuel mixtures. Because of that, regulatory authorities consider FP measurements to classify fuel or flammable liquids, and to develop guidelines for the transport, storage, disposal, and handling of chemical products .
