Understanding the commonalities among previous chemical process incidents can help mitigate recurring incidents in the chemical process industry and will be useful background knowledge for designers intending to foster inherent safety. The U.S. Chemical Safety and Hazard Investigation Board (CSB) reports provide detailed and vital incident information that can be used to identify possible commonalities. This study aims to develop a systematic approach for extracting data from the CSB reports with the objective of establishing these commonalities. Data were extracted based on three categories: attributed incident causes, scenarios, and consequences. Seventeen causal factors were classified as chemical indicators or process indicators. Twelve chemical indicators are associated with the hazards of the chemicals involved in the incidents, whereas five process indicators account for the hazards presented by process conditions at the time of the incident. Seven scenario factors represent incident sequences, equipment types, operating modes, process units, domino effects, detonation likelihood for explosion incidents, and population densities. Finally, three consequence factors were selected based on types of chemical incidents, casualties, population densities, and economic losses. Data from 87 CSB reports covering 94 incidents were extracted and analyzed according to the proposed approach. Based on these findings, the study proposes guidelines for future collection of information to provide valuable resources for prediction and risk reduction of future incidents.

CSB事件调查的精妙之处可以教给我们什么?CSB调查的化学过程事件中信息特征的详细分析

了解以前的化学过程事件之间的共性可以帮助减轻化学过程行业中的重复事件,并且对于打算培养固有安全性的设计者将是有用的背景知识。美国化学安全与危险调查委员会(CSB)的报告提供了详细的重要事故信息,可用于识别可能的共性。这项研究旨在开发一种系统的方法,以从CSB报告中提取数据,以建立这些共同点。根据以下三类提取数据:归因的事件原因,场景和后果。十七个因果因素被分类为化学指标或过程指标。十二种化学指标与事件所涉及的化学物质的危害有关,而五个过程指标则说明了事件发生时过程条件所带来的危害。七个场景因素代表事件顺序,设备类型,操作模式,过程单位,多米诺骨牌效应,爆炸事件的爆炸可能性和人口密度。最后,根据化学事故的类型,人员伤亡,人口密度和经济损失,选择了三个后果因素。根据提议的方法,从87个CSB报告中涵盖了94个事件的数据被提取和分析。基于这些发现,研究提出了未来信息收集的指南,为预测和降低未来事件的风险提供了宝贵的资源。七个场景因素代表事件顺序,设备类型,操作模式,过程单位,多米诺骨牌效应,爆炸事件的爆炸可能性和人口密度。最后,根据化学事故的类型,人员伤亡,人口密度和经济损失,选择了三个后果因素。根据提议的方法,从87个CSB报告中涵盖了94个事件的数据被提取和分析。基于这些发现,研究提出了未来信息收集的指南,为预测和降低未来事件的风险提供了宝贵的资源。七个场景因素代表事件顺序,设备类型,操作模式,过程单位,多米诺骨牌效应,爆炸事件的爆炸可能性和人口密度。最后,根据化学事故的类型,人员伤亡,人口密度和经济损失,选择了三个后果因素。根据提议的方法,从87个CSB报告中涵盖了94个事件的数据被提取和分析。基于这些发现,研究提出了未来信息收集的指南,为预测和降低未来事件的风险提供了宝贵的资源。根据化学事故的类型,人员伤亡,人口密度和经济损失,选择了三个后果因素。根据提议的方法,从87个CSB报告中涵盖了94个事件的数据被提取和分析。基于这些发现,研究提出了未来信息收集的指南,为预测和降低未来事件的风险提供了宝贵的资源。根据化学事故的类型,人员伤亡,人口密度和经济损失,选择了三个后果因素。根据提议的方法,从87个CSB报告中涵盖了94个事件的数据被提取和分析。基于这些发现,研究提出了未来信息收集的指南,为预测和降低未来事件的风险提供了宝贵的资源。
