摘要
针对当前事故模式表述不明确、不清晰的问题和隐患识别不专业、不全面的缺陷,给出事故模式的一般性定义、内涵及提取步骤,并解释事故模式与隐患的关系,提出基于事故模式的生产现场隐患点的查找方法。参考《企业职工伤亡事故分类》(GB 6441—1986),统计2000—2022年化工行业较大及以上安全事故,分析不同类别隐患的发生概率。通过分析某石化企业丙烯装车场景下的事故根源、屏障失效及事故类型,提炼丙烯装车事故模式,生成隐患特征表。结果表明:不安全状态中第一类隐患、不安全行为中第一、第六、第十三类隐患在化工行业典型事故类型中发生的概率较高。丙烯装车场景下针对防止丙烯泄漏所设屏障识别隐患条目数最多,约占48.94%;N=1,M=1、m=6,M=6、m=8,M=13涉及的隐患条目发生概率约占各类目总体发生概率的49.23%,12.78%,14.44%和26.11%,应当作为防护重点。
In response to the current problems of unclear and ambiguous accident pattern descriptions and the deficiencies of unprofessional and incomplete identification of hidden dangers,this study provided a general definition,connotation,and extraction steps for accident model.The relationship between accident mode and hidden dangers was explained,and a method for finding hidden danger points in production sites based on accident mode was put forward.Referring to the“classification for casualty accidents of enterprise staff and workers(GB 64411986)”,statistics on larger and higher safety accidents in the chemical industry from 2000 to 2022,and the probability of occurrence of different categories of hidden dangers were analyzed.By analyzing the accident root causes,barrier failures and accident types in the propylene loading scenario of a petrochemical enterprise,the accident mode of propylene loading was extracted and the hidden danger characteristic table was generated.The results showed that the probability of occurrence of the first type of hidden danger in unsafe state and the first,sixth and thirteenth types of hidden danger in unsafe behavior was higher in the typical accident types of chemical industry.The number of hidden danger items identified for preventing propylene leakage by setting barriers in the propylene loading scenario accounted for the highest proportion,approximately 48.94%.The occurrence probability of hidden danger items involved in N=1,M=1 and m=6,M=6 and m=8,M=13 accounted for 49.23%,12.78%,14.44%and 26.11%of the total occurrence probability of all categories,and should be a priority for protection.
