摘要

The fire accident of petroleum storage and transportation has the characteristics of difficult disposal, wide range of influence, and a long-term hazard. Many derivative accidents or secondary accidents caused in the emergency process show that there are some potential risk sources in the process of accident emergency disposal. Effectively identifying these potential risk sources is the key for the active protective design in advance, and it is a minimum cost mean to prevent and reduce accident harm. In the paper, from the perspective of analyzing the nature of accident's development and evolution process, the causal relationship between events is studied based on the accident-causing theory. The event causal chain is built in according with the order of event occurrence. The risk sources of accident are mined and identify from the node of event chain, and the hierarchical identification method oriented accident's risk sources is established. For accident's risk sources, the possible design measures in advance can be given from the perspective of principle design, structural design and control design. For design measure's risk sources in emergency process can be mined by using man-human engineering method, and the graded risk sources identification method oriented secondary accidents is established. Combining the two methods, the hierarchical risk source identification method connected with event causal chain is put forward so as to effectively identify these potential risk sources in emergency process. Finally, oil pipeline explosion accident of dalian's xinggang harbor on July 16, 2010 is taken as a case to verify the feasibility of proposed method.
