集输站场是一个连续的生产过程,生产介质具有火灾爆炸危险性。传统的作业条件危险性分析仅能从事故发生可能性、暴露频率、事故所产生的后果角度,进行风险评价。没有考虑集输站场工作岗位间的差别。文章在分析了集输站场岗位危险有害因素的基础上,运用模糊评价的基本理论,建立了集输站模糊风险评价模型,评价了某集输站场,确定风险等级为Ⅳ级,风险处于可接受水平。
The gathering station is a continuous production process, the production medium has the danger of fire and explosion. The traditional risk analysis of operating conditions can only carry out risk assessment from the perspective of accident probability, exposure frequency and the consequences of accidents. Did not consider the difference between the collection and transmission station job. Based on the analysis of hazardous factors in the stations of gathering and transporting stations, this paper establishes the fuzzy risk assessment model of gathering stations by using the basic theory of fuzzy evaluation, evaluates a certain collection station and determines the risk level as grade Ⅳ, Acceptable level.
