Fault Tree Analysis of a Gas Storage Yard

This paper briefly introduces the concept, origin, fault tree analysis method and simple calculation formula, based on the fault tree analysis and understanding, and its calculation method and idea was applied to specific instances of fire control design, for a combustible gas cylinders yard fire control design of the status quo, combustible gas cylinder storage area for the storage, storage containers, such as fire hazard analysis, on this basis, the disaster accident tree analysis, through mapping the three most possible accident tree, using expert scoring statistics and the formula to calculate structure importance of each basic event obtained three most likely to produce the probability of accident consequence, the probability can provide important basis for the design of the accident scene, and then countermeasures of fire safety assessment for this kind of place, and add the necessary fire fighting measures to provide data support.
