对暴露在火灾中的车载氢动力汽车存储进行了定量风险评估。这种风险被定义为每辆车火灾造成的生命代价和每辆车的年死亡率。结果表明，提高储罐的耐火等级，可将风险大大降低到可接受的水平。爆炸波和火球是经过验证的工程工具，用于计算爆炸波和火球的危险距离。爆炸波和火球在火灾中发生灾难性的储罐破裂后，作用在各个方向，与喷射火灾相比具有更大的危险距离。死亡现金值、车辆起火的概率和热启动压力释放装置的故障取自已公布的来源。采用易损性概率函数计算应急作业不能有效控制火灾和防止坦克破裂的概率。风险表示为船载存储的耐火等级的函数。
A quantitative risk assessment of onboard hydrogen-powered vehicle storage, exposed to a fire, is performed. The risk is defined twofold as a cost of human life per vehicle fire, and annual fatality rate per vehicle. The increase of fire resistance rating of the storage tank is demonstrated to drastically reduce the risk to acceptable level. Hazard distances are calculated by validated engineering tools for blast wave and fireball, which follow catastrophic tank rupture in a fire, act in all directions and have larger hazard distances compared to jet fire. The fatality cash value, probabilities of vehicle fire and failure of thermally activated pressure relief device are taken from published sources. A vulnerability probit function is employed to calculate probability of emergency operations' failure to control fire and prevent tank rupture. The risk is presented as a function of fire resistance rating of onboard storage.
