A good engineer will never let you down, man!
A Pump is a Heart of any plant and of course, your Heart is the closest pump to you.
Imagine, if your Heart stops, what will happen to you? Now imagine, if a pump stops?
That is why a running pump always has a standby pump!
Moreover, if something goes wrong, or if taken for granted anything can happen.
For instance, if this was a running pump supplying a cooling water from the cooling tower to a reactor, specifically where an exothermic reaction is taking place. And if the pump had stopped for some reason, let say because of some blockage or plugged strainer, thereby causing cavitation and low pump output, by the time your interlocks work or control valve take actions, this could have become next runaway plant case.
