Fault Tree Analysis of Potential Safety Risk in Explosion Elimination Processing of LPG Tanks

摘要

The potential dangerous factors in explosion elimination processing of LPG tanks in a chemical plant in Xiangfan city, Hubei province, are systematically analyzed from the top tree event to the bottom tree event or from the results to the causes by a fault tree taking a fire or explosion accident for the top tree event. The minimum cut-set of the fault tree is obtained, and the major dangerous factors are realized, and the corresponding prevention measures to ensure the safety of the explosion elimination processing are suggested.
