摘要:

为预防城市燃气事故的发生,首先,通过“2-4”模型(24 Model)不安全动作原因因素编码和生产过程危险有害因素代码,分析90起城市燃气死亡事故不安全动作;然后,以修正的不安全动作发生概率和事故危险指数为基础,构建并优化城市燃气事故行为风险评估模型;最后,采用蒙特卡罗法研究4类城市燃气事故相关方的行为风险后果值,并运用敏感度分析得到每类相关方的不安全动作对行为风险影响程度。结果表明:燃气经营者行为风险最大,其次是燃气使用者和燃气工程参与者行为风险,其他第三方单位行为风险最小;事故隐患排查治理工作不落实、燃气燃烧器具或燃气设施使用不合规、未按规范实施职业安全卫生管理或技术服务这3种不安全动作对城市燃气事故行为风险影响较大。

Abstract:

In order to prevent the occurrence of urban gas accidents, unsafe acts of 90 urban gas fatal accidents were firstly analyzed through the code of unsafe act factors of 24Model, and classification and code for hazardous and harmful factors in production process. Then, based on the modified probability of unsafe acts and accident risk index, the behavioral risk assessment model of urban gas accidents was constructed and optimized. Finally, the Monte Carlo method was used to study behavioral risk consequence values of four types of parties relating to urban gas accident, and sensitivity analysis was used to obtain the influence degree of unsafe acts of each type of related party on behavioral risk. The results shows that the behavior risk of gas operators is the highest, followed by gas users and gas engineering participants. The risk of other third party units is the lowest. In addition, three kinds of unsafe acts have great impacts on the risk of urban gas accident behavior, including "insufficient implementation of accident hidden danger investigation and rectification", "non-compliant use of gas appliances or facilities" and "illegal implementation of occupational safety and health management or technical services".
