摘要
为有效预防化工行业受限空间事故,减少人员伤亡,基于化工行业受限空间事故统计数据,明确事故发生规律.应用24Model系统探究"4·15"重大着火中毒事故致因要素,并深入挖掘要素间的内在关联,计算各致因要素总输入输出度,由此明确预防措施的优先级.研究结果表明:我国化工行业受限空间事故发生数呈平稳变化趋势,事故级别多为较大事故(占比65.6％),主要事故类型为中毒和窒息事故(占比59.1％).在"4·15"重大着火中毒事故致因要素中,车间地下室不正确存放LMZ冷媒增效剂总输入输出度最大(CB1=0.44),具有预控的优先级别.研究结果为化工行业受限空间事故预防措施的制定提供数据支持及策略参考.
Abstract
In order to effectively prevent confined space accidents in the chemical industry and reduce casualties,based on the statistical data of confined space accidents in the chemical industry,the rules of accident occurrence were clarified.The 24Model system was used to explore the causal factors of the"4·15"major fire poisoning accident,and deeply explore the internal correlation between the factors,calculate the total input and output degree of each causal factor,and thus clarify the priority of preventive measures.The researchs result indicated that the number of confined space accidents in China's chemical industry showed a stable trend of change,with the majority of accidents classified as major accidents(accounting for 65.6％),and the main types of accidents were poisoning and suffocation(accounting for 59.1％).Among the factors causing the"4·15"major fire poisoning accident,the total input and output of LMZ refrigerant synergist incorrectly stored in the workshop basement is the highest(C(B1)=0.44),which has a priority level of pre-control.The research results provide data support and strategic reference for the development of accident prevention measures in confined space in chemical industry.
