随着我国燃气需求量不断增加,城镇燃气系统已经深入每家每户,城镇燃气管道是国家城镇化建设中的重要安全工程,燃气本身具有很高的危险性,燃气管道安全隐患将直接威胁到人身安全,其安全性受到国家、地方政府和燃气公司的高度关注。燃气管道的安全运行,保障用户人身安全是燃气工作的重点。目前,城市的燃气管道安全评估体系一直没有得到完善,本文从事故统计和风险评估等方面讨论了城镇燃气安全风险评估及控制,对城镇燃气管道的定性和定量风险评估方法进行了综述,探讨了控制方法适用性,找出城镇燃气风险的因素,进行安全检查表分析,根据严重性,对城镇燃气管道事故综合分析,评估风险的严重性,提出控制措施,以降低城市燃气管道的运行风险,提高燃气管道运行的安全性。
With the increasing demand for gas in our country, the gas system in cities and towns has been deepened for every household. The urban gas pipeline is an important safety project in the urbanization of our country. The gas itself is very dangerous. The potential safety hazard of the gas pipeline will be directly threatened Personal safety and safety are highly regarded by the state, local governments and gas companies. The safe operation of gas pipelines to protect the personal safety of users is the focus of gas work. At present, the city’s gas pipeline safety assessment system has not been perfected. This article discusses the urban gas safety risk assessment and control from the aspects of accident statistics and risk assessment. The qualitative and quantitative risk assessment methods of urban gas pipeline are reviewed. Control the applicability of the method, find out the factors of town gas risk, carry out the safety checklist analysis, according to the seriousness, analyze the seriousness of the urban gas pipeline accident, assess the seriousness of the risk, put forward the control measure, in order to reduce the urban gas pipeline operational risk, Improve the safety of gas pipeline operation.
