"This study considers the flammability hazard associated with the pouring of gasoline from a portable gasoline container (PGC) in an area containing a potential ignition source. In this scenario a flame may propagate into the PGC and cause an explosion if a flammable environment exists along the length of the pour spout and into the PGC headspace. In order to quantify this hazard, experiments are conducted to measure the flammable vapor concentration within this area under various conditions of temperature, liquid volume, and container pour angle. It is found that liquid fuel volumes as high as 30 mL in a 5-gallon PGC are capable of producing a flammable vapors within the PGC headspace. Finally, a mathematical model is presented to predict the flammability hazard under various conditions."
