Abstract The present study relates to an arson fire incident that recently occurred at an animated film production studio in Kyoto, leading to gasoline spills on the first floor instantly causing ignition in the building, claiming the lives of 35 people. Thus, with many fatalities often associated to such arson fire caused by gasoline, this study focuses on features including inflammability, combustibility, and volatility as the fire hazards of gasoline. The vapor pressure, flash point, and evaporation rate of gasoline are measured, and a prediction model is developed to monitor the changes in the vapor pressure and flash point of gasoline along with the progress of evaporation. In addition, combustion experiments of gasoline spills on the floor and ignition tests of gasoline vapor generated from the gasoline spills were conducted. Finally, an evaporation and diffusion model of the gasoline spill is proposed, while the ignition and explosion hazards caused by gasoline spills are deduced. The proposed models in this study are expected to be utilized for hazard evaluations in an arson fire caused by gasoline and the fundamental data for fire phenomenon analysis.

汽油泄漏引发火灾隐患

摘要 本研究涉及最近发生在京都动画电影制片厂的纵火事件,导致一楼的汽油泄漏立即引起建筑物着火,夺去了 35 人的生命。因此,由于汽油引起的此类纵火事故通常会导致许多死亡事故,因此本研究重点关注汽油的易燃性、可燃性和挥发性等特征。测量汽油的蒸气压、闪点和蒸发率,并建立预测模型以监测汽油的蒸气压和闪点随蒸发进程的变化。此外,还进行了地板上汽油泄漏的燃烧试验和汽油泄漏产生的汽油蒸气的着火试验。最后,提出了汽油泄漏的蒸发扩散模型,推导了汽油泄漏引起的着火和爆炸危险。本研究中提出的模型有望用于汽油引起的纵火火灾的危害评估和火灾现象分析的基本数据。
