To enhance the identification and control of accident risks in confined space operations in industrial and commercial enterprises, a socially acceptable risk standard for such operation accidents was established, and a risk grading study based on F-N curve was conducted. First, historical data on significant and higher-level accidents in confined space operations from 2014 to 2021 were analyzed statistically in terms of fatalities, accident frequency, and the number of enterprises involved, in order to identify accident patterns. Then, considering accident frequency and fatality consequences, a socially acceptable risk standard was developed based on ALARP criteria, and F-N curve was plotted. Finally, a risk grading management model was established based on three risk zones-intolerable, acceptable, and negligible. The control measures were proposed from both enterprise and individual perspectives. The results show that for accidents with 3 to 10 fatalities, the frequency falls within the magnitude of 10-6-10-4. The F-N curve with a slope of -4.033 is used to divide three distinct risk levels, helping to clarify the boundaries of risk levels and highlight management priorities.

为提升工贸企业有限空间作业事故风险识别与管控水平,建立有限空间作业事故社会可接受风险标准,开展基于F-N曲线的风险分级研究。首先,基于2014—2021年工贸企业有限空间作业较大及以上事故数据,从伤亡人数、事故数量、企业数量等维度进行统计分析,掌握事故特征;然后,结合事故频率与伤亡后果,基于最低合理可行(ALARP)准则制定社会可接受风险标准,绘制F-N曲线图;最后,依据不可容忍、可接受和可忽略3个风险区域,建立风险分级管理模式,并分别从企业与个人角度提出管控措施。结果表明:死亡在3~10人的可接受风险事故频率数量级在10-6~10-4之间;以斜率为-4.033的F-N曲线为基础划分的3个不同风险等级区域,有助于明确风险等级边界,突出分级管理重点。

为提升工贸企业有限空间作业事故风险识别与管控水平,建立有限空间作业事故社会可接受风险标准,开展基于F-N曲线的风险分级研究。首先,基于2014—2021年工贸企业有限空间作业较大及以上事故数据,从伤亡人数、事故数量、企业数量等维度进行统计分析,掌握事故特征;然后,结合事故频率与伤亡后果,基于最低合理可行(ALARP)准则制定社会可接受风险标准,绘制F-N曲线图;最后,依据不可容忍、可接受和可忽略3个风险区域,建立风险分级管理模式,并分别从企业与个人角度提出管控措施。结果表明:死亡在3~10人的可接受风险事故频率数量级在10-6~10-4之间;以斜率为-4.033的F-N曲线为基础划分的3个不同风险等级区域,有助于明确风险等级边界,突出分级管理重点。

To enhance the identification and control of accident risks in confined space operations in industrial and commercial enterprises, a socially acceptable risk standard for such operation accidents was established, and a risk grading study based on F-N curve was conducted. First, historical data on significant and higher-level accidents in confined space operations from 2014 to 2021 were analyzed statistically in terms of fatalities, accident frequency, and the number of enterprises involved, in order to identify accident patterns. Then, considering accident frequency and fatality consequences, a socially acceptable risk standard was developed based on ALARP criteria, and F-N curve was plotted. Finally, a risk grading management model was established based on three risk zones-intolerable, acceptable, and negligible. The control measures were proposed from both enterprise and individual perspectives. The results show that for accidents with 3 to 10 fatalities, the frequency falls within the magnitude of 10-6-10-4. The F-N curve with a slope of -4.033 is used to divide three distinct risk levels, helping to clarify the boundaries of risk levels and highlight management priorities.
