This work is to address the scientific assessment methodology of fire protection power and theoretical fire resource requirements for hazardous chemicals storage fires. The evolution chain of accident, accident risk and its impact on the surrounding area of hazardous chemicals storage fire and explosion accidents are analyzed. According to different storage modes of hazardous chemical substances, the fuzzy comprehensive assessment method was used to construct a secondary evaluation index group for fire resource requirements. The judgment matrix is established to evaluate the index weight of each influence factor of foam extinguishing efficiency based on the analytic hierarchy process. A forecasting model of fire resource demand has been constructed. The principal results are that the coefficient of foam dosage of storage rank, warehouse and stock dump in actual combat is 3.3, 3.2949, and 3.3147, respectively. Combined with the fire geographic information system, fire equipment can be allocated more reasonably. This can maximize the fire extinguishing performance of the equipment and improve the firefighting of hazardous chemicals scientifically and effectively. The research results are of great significance for the scientific prediction of the fire protection resources requirements of hazardous chemicals storage fires.

危险化学品储存的消防资源需求评估模型

这项工作是针对科学的消防能力评估方法和危险化学品存储火灾的理论火资源要求。分析了事故，事故风险的演化链及其对危险化学品存储火灾和爆炸事故周围环境的影响。根据危险化学物质的存储方式的不同，采用模糊综合评判法建立了消防资源需求二级评价指标组。建立基于层次分析法的泡沫灭火效率影响因素指标权重的评价矩阵。建立了消防资源需求预测模型。主要结果是泡沫等级存储量的系数，在实际战斗中，仓库和库存转储分别为3.3、3.2949和3.3147。结合消防地理信息系统，可以更合理地分配消防设备。这样可以最大程度地发挥设备的灭火性能，科学有效地改善危险化学品的灭火性能。研究结果对科学预测危险化学品贮存火的消防资源需求具有重要意义。
