▪ The block valves in a line to jackets, coils, reboilers and similar items
which in themselves are not directly connected to the confine space are closed and tag-out applied. The only exception would be the use of external cooling water on vessel jackets or coils during hot weather.对 于那些安装在夹套,盘管,再沸器管线或类似情况的切断阀,这些系统 本身并不与进行工作的限制空间相连,这些阀门必须关闭并加以标示。 仅对高温天气用于容器夹套或盘管的冷却水阀门除外。
▪ A blind or stopper plate as single isolation measure is only acceptable
in cases where above mentioned methods are technically impossible. 在管线中插入一块盲板作为一个单独的隔离措施,仅仅在上述提及的所 有方法从技术上不可实现的情况下可以使用。
