Teng Honghu · Industrial Safety and Environmental Protection · 2013
Secondary water supply is an important part of water-supply systems,which plays an irreplaceable pole in ensuring the safety of water-supply.In this paper,the fault tree analysis(FTA)method is applied to conduct analysis on the insufficientwater flow and pressure in secondarywater supply,inwhich the fault tree is compiled and the importance degree of the basic events is analyzed.The results show that there existmany major risk sources in the design and operations of facilities of secondary water supply and based on the properties of risk sources,some reasonable suggestions are put forward,providing references for the establishment of safe municipal water-supply measures.
