I worked somewhere with an uncovered EPO, which was okay until we had a
telco tech in who was used to a different data center where a similar
looking button controlled the door access, so he reflexively hit it
on his way out to unlock the door.  Oops.

Also, consider what's on generator and what's not.  I worked in a corporate
data center where we lost power.  The backup system kept all the machines
running, but the ventilation system was still down, so it was very warm very
fast as everyone went around trying to shut servers down gracefully while
other folks propped the doors open to get some cooler air in.
