问题 问答题 简答题

由不注意引起的事故以及有哪些改进措施

答案

参考答案:

根据研究引起不注意的原因有:

(1)强烈的无关刺激的干扰。

(2)注意对象设计欠佳。

(3)注意的起伏。注意的起伏是指人对注意客体不可能长时间保持高意识状态,而是按照间歇地加强或减弱规律变化。因此,越是高度紧张需要精力集中的作业,其持续时间越不宜长,因为低意识期间容易导致故。

(4)意识水平下降导致注意力分散。

改进措施:

(1)建立冗余系统,为确保操作安全,在重要岗位上,多设1~2个人平行监视仪表的工作。

(2)为防止下意识状态的失误,在重要操作之前,对操作内容确认后再动作。

(3)改进仪器、仪表的设计,使其对人产生非单调刺激或悦耳、多样的信号,避免误解。
