There will be a big red switch somewhere to cut
all power in the event of (for instance) a fire. This will bring all power down in an uncontrolled manner leading to all sorts of bad stuff. Activating it when the building isn't actually on fire would be a Very Bad Thing to do.
Similarly, just turning everything back on again and assuming that it will all just start up and resume would be a Very Bad Thing.
