涉冬奥会场馆外工业场所火灾风险预警指标

为了预防冬奥会场馆外工业场所火灾事故，开展重点场所和关键设施火灾风险识别，研究多因素综合风险评估指标体系。通过典型事故案例统计分析和现场火灾隐患识别排查，确定了以涉氨制冷场所、发电厂、物流仓储企业为主的重点场所和关键设施的风险点；基于风险理论从场所固有火灾风险、风险减缓措施和现实风险角度，构建了冬奥敏感度、区域特征、建筑特性、消防设施状况和消防安全管理、外部救援力量为主的多因素综合风险评估指标体系，采用风险指数分级法确定风险指标重要度。研究表明：该多因素火灾风险评估指标体系实现了关键风险因素的动态数据获取和定量化，具有多源风险识别和动态研判作用，可较客观地提前预警影响冬奥会的重大工业火灾风险。

Fire risk alarming index of industrial buildings outside of winter Olympic venues

In order to prevent fire accidents of industrial buildings outside of winter Olympic venues, the multiple factors and comprehensive risk assessment index system was studied by identifying fire risk factors of key place and facilities. The risk points of the key place and facilities were analyzed and classified, by statistical analysis of typical accident cases and potential fire identifications on sites, including ammonia-related refrigeration sites, power plants and supply chain financing. On account of risk theory with inherent fire risk, risk mitigation measures and real fire risk, the multiple factors and comprehensive risk assessment index system was presented, including sensitivity of winter Olympic games, regional characteristics, buildings properties, firefighting facilities condition, fire safety management and external rescue force. And the important degree of risk indexes was divided by risk ranking method.Some time-varying risk factors were dynamically collected and quantified, and this fire risk index system can identify and analyze multi-source risk with time-varying characteristics, and therefore improve the level of fire risk warning for industrial buildings outside of winter Olympic venues.
