问题 单项选择题

为了提高设备的本质安全度,在工业锅炉设计上,工程设计人员采用了两个安全阀的设计方案。这种设计理念属于( )。

A.安全隔离
B.个体防护
C.设置薄弱环节 D.逐渐泄压

答案

参考答案:C

解析:常用的减少事故损失的安全技术有隔离、个体防护、设置薄弱环节、避难与救援等。隔离包括隔开,封闭和缓冲等;个体防护主要是指配备和使用防护用品;设置薄弱环节主要是防止能量作用于被保护的人或物,如锅炉上的易熔塞、电路中的熔断器等,在工业锅炉设计上,工程设计人员采用了两个安全阀(安全阀的作用是:当容器内压力超过某一定值时,依靠介质自身的压力自动开启阀门,迅速排出一定数量的介质。当容器内的压力降到允许值时,阀门又自动关闭,使容器内压力始终低于允许压力的上限,自动防止因超压而可能出现的事故,所以安全阀又被称为压力容器的最终保护装置)的设计方案,就属于此类情况;避难与救援主要是设置避难场所,当发生事故时,能及时撤离。
