The urban gas pipeline is buried underground. It is in a certain pressure and its medium is flammable and explosive easily, which threatens safety of personnel and property around the pipeline greatly. A new safety management method of urban gas pipelines is proposed by analyzing the relationship between safety management and risk management. With the engineering example in a certain city, the potential risks are estimated by the application of risk matrix and fuzzy comprehensive evaluation, which can determine the nature of risks and take reasonable measures to achieve the purposes of safety management.
