一、事故经过2012年10月15日在20:48左右(电脑和视频上查出)在氯气液化岗位贮槽至液下泵的流料管上压力表发生液氯泄漏,20:57左右,氯化氢液氯岗位操作人员发现报警,当时以为是氯化氢的合成炉下氯气报警,因此氯化氢岗位操作工去氯化氢现场检查。此时液氯当班长〈A〉也到液氯去检查一下,走到门口发现液氯这里有氯气,立即回过来告诉〈B〉液氯里氯气浓度很大,并立即向调度报告情况, First, the accident after October 15, 2012 at about 20:48 (computer and video) in the chlorine liquefied post storage tank to the liquid pipe pressure gauge liquid chlorine leak, about 20:57, Hydrochloric acid liquid chlorine post operator found the alarm, then thought it was hydrogen chloride synthesis furnace chlorine alarm, so hydrogen chloride hydrogen hydrogen site operators to check. At this time when the liquid chlorine monitor also to liquid chlorine to check, go to the door found liquid chlorine chlorine, immediately came back to tell liquid chlorine chlorine concentration, and immediately report to the scheduling situation,
