Fault tree analysis describes dynamic process of the beginning and developing in the accident. It helps find out direct and indirect reasons of the accident. According to analysis on fault tree of fire and explosion in ethylene oxide production, eleven basic events were got. With minimal cut sets and minimal path sets, top event probability was solved, and basic event importance degree was analyzed. The main elements to cause ethylene oxide fire and explosion accident were determined, which can provide reliable foundation for safety management in ethylene oxide production.
