That's Nothing
I had a colleague a bunch of years back working in a large Datacentre that was pulling in a bundle of Cat5 cables for a new install through the big floor tile trench they had opened & just as he got to the end of the pull the whole place fell silent ! Turns out his derrière had bumped into an emergency power shutdown button that did NT have a protective cover, Oops ! What me, nah run away :)
