摘　　要：针对某个固有风险不高的涉危企业甲类库房距离厂外道路路边不满足《建筑设计防火规范[2018版]》要求的案例,通过危险与可操作性分析(HAZOP)和保护层分析(LOPA),并使用Gexcon公司开发的泄漏及爆炸危害分析软件FLACS进行事故后果模拟,来探讨建筑物作为保护层的可能性。采用HAZOP和LOPA分析库房内戊烷储罐发生火灾爆炸情景,不能确定厂外道路上活动人员和车辆的安全情况,通过FLACS软件进一步进行事故后果模拟,显示库房的防火墙可以作为保护层,火灾爆炸不会伤害到厂外道路上的活动人员和车辆。In this paper,aiming at a case that a class A warehouse of a dangerous enterprise with low inherent risk does not meet the requirements of"Code for Fire Protection Design of Buildings[2018 Edition]"from the roadside of the road outside the factory,through hazard and operability analysis(HAZOP)and protective layer analysis(LOPA),and using the leakage and explosion hazard analysis software FLACS developed by Gexcon Company to simulate the accident consequences,the possibility of building as a protective layer is discussed.With HAZOP and LOPA analyses of the fire and explosion scenarios of the pentane storage tanks in the warehouse,we could not determine the safety of the personnel and vehicles on the road outside the factory.We then used FLACS software to further simulate the accident consequences,which showed that the firewall of the warehouse could be used as a protective layer,and the simulated fire and explosion did not hurt the personnel and vehicles on the road outside the factory.
