Natural disasters such as large earthquakes may rapidly result in cascading events such as post-earthquake fires (PEFs) to trigger. This is particularly the case in industrial facilities which is well known as natural-hazard triggered technological accidents (NaTechs). This study provides a response framework for NaTechs caused by earthquake in fuel storage facilities. To do this, seismic vulnerability of fuel storage tanks and possible damage fashions are studied. Considering fuel leakages can result in PEFs, possible scenarios are simulated numerically using Process Hazard Analysis Software Tool (PHAST). A case study including 20 fuel tanks adjacent one to another is investigated to simulate a domino effect when different arbitrary tanks start to ignite; hence, the worst case scenario can be determined. Based on the results of the case studied, inability to extinguish the possible PEFs over less than 9 min can lead to spreading them to the adjacent tanks. The results indicate that it takes about 40 min the adjacent tanks involve in the fires. Therefore, it is of paramount importance to provide an emergency response plan in advance to properly respond to the fires. The study here also highlights the role of preventive strategies in reducing the associated risks of PEFs in industrial facilities.

诸如大地震之类的自然灾害可能会迅速导致级联事件的发​​生，例如引发地震后的火灾。在工业设施中尤其如此，这就是众所周知的自然灾害引发的技术事故（NaTechs）。这项研究为NaTechs因燃料存储设施中的地震而提供了响应框架。为此，研究了燃料储罐的地震易损性和可能的​​损坏方式。考虑到燃油泄漏可能导致PEF，可以使用过程危害分析软件工具（PHAST）对可能的情况进行数值模拟。研究了一个包括20个彼此相邻的油箱的案例研究，以模拟不同的任意油箱开始点火时的多米诺效应。因此，可以确定最坏的情况。根据案例研究的结果，在不到9分钟的时间内无法扑灭可能的PEF，可能会导致它们散布到相邻的储罐中。结果表明，相邻储罐参与火灾大约需要40分钟。因此，事先提供应急计划以正确应对火灾至关重要。此处的研究还强调了预防策略在降低工业设施中PEF相关风险方面的作用。
