摘要:

通过城市燃气运营事故案例、安全检查结果与事故统计分析的诸多数据,识别了城市燃气运行过程中存在的各种可能的风险因素,采用基于鱼骨图的风险分析方法,得出了管材及施工质量不高、第三方破坏、设备管网资料缺失、地下管网地理信息缺失、保养不到位、未预防性更新改造、用户安全知识不足、员工安全意识与知识不足、未严格加臭、规划落后、执行不到位11个城市燃气运营的重要风险因素,并据此提出了防范风险的措施及建议。

Abstract:

Based on data of accident case of the urban gas operations, safety inspection result and accident statistical analysis, a variety of possible risk factors are identified in the process of city gas operation. And using the risk analysis method based on a fishbone diagram, 11 important risk factors of city gas safety operation are obtained, such as low pipe and construction quality, the third party damage, loss of pipe network data, loss of geographic information of underground pipe network, not preventive upgrading, lack of safety knowledge for users and also lack of safety awareness to employees, no odorization, planning backward, and lack of enforcement, etc. Some advices are put forward to prevent risks.
