为提高化工园区安全生产工作的有效性,从本质安全策略、风险控制策略、制度与文化策略3个层次构建了化工园区安全保障体系,详细阐述了体系中每个层次的核心要素和关键技术。其中,本质安全策略包括安全生产布局优化、产业链优选和安全容量控制3项关键技术,风险控制策略包括重大工业事故隐患辨识与控制、多米诺效应事故风险分析与控制、安全生产预警和安全生产应急救援4项关键技术,制度与文化策略包括安全生产主体责任制度与安全文化建设2方面内容。体系综合了近年来化工园区安全管理与技术方面的研究成果。 In order to improve the safety of production in the chemical park, the safety protection system of chemical park was constructed from the three levels of intrinsic safety strategy, risk control strategy, system and cultural strategy. The core elements and key technologies of each level in the system were elaborated. Among them, the essential safety strategy includes three key technologies of production safety layout optimization, industrial chain optimization and safety capacity control. The risk control strategies include identification and control of major industrial accidents, risk analysis and control of domino effect accidents, production safety early warning and work safety emergency Rescue 4 key technologies, systems and cultural strategies include the main body of responsibility for safety in production and safety culture building two aspects. System combines the chemical park safety management and technology in recent years, research results.
