单项选择题 案例分析题

某植物油加工厂生产采用的是油脂浸出工艺,以先进的化工萃取法提取大豆油脂,生产工具有机械设备、厂内运输车辆等,生产的植物油闪点大于60℃。植物油浸出车间为单层厂房,每层建筑面积为125m2,在同一时间的作业人员不超过10人。为了做好危险源辨识,厂安全主管甲给全厂职工进行了一次安全培训,讲述了危险源、事故隐患、事故致因理论等。甲指出,由于植物油及其加工原料有火灾、爆炸危险性,因此我厂存在大量的危险源和事故隐患,甚至是重大危险源和重大事故隐患。比如,植物油浸出过程中,植物油临时储罐的储油量很大,构成重大危险源;植物油浸出车间有作业人员,作业人员可能有误操作,因此植物油浸出车间就是重大事故隐患。甲进一步解释说,危险的程度可用危险度表示,危险度是生产系统中事故发生的可能性与严重性的函数,也就是说,生产系统中事故发生的可能性或严重性越大,生产系统的危险度就越大。因此在生产过程中应尽量降低事故发生的可能性和严重性,通过降低人的不安全行为来降低事故发生的可能性,通过降低物的不安全状态降低事故发生的严重性。比如,减少植物油加工原料(大豆)储存区的原料储存量可以降低储存区的事故严重性。再比如,植物油的成品油储罐中储存的植物油越少,其事故发生的严重性越小,因此为了降低成品油储罐区的风险,应将大的储油罐改造为多个小储油罐,即当需要储存5000t成品植物油时,用10个500t储罐比用5个1000t储罐的风险小。

下列关于危险源与事故隐患关系的说法正确的是()。

A.事故隐患一定是危险源

B.危险源一定是事故隐患

C.重大危险源一定是事故隐患

D.重大事故隐患一定是重大危险源
