The fire chief does not want any delay in or out during a fire period.
The security chief does not want any unauthorized personnel to enter or leave the building, period, including the fire chief and his crew of scoundrels- why, for all we know, they set that fire specifically to infiltrate the secure facility! Security requirements need those doors to fail locked during power outages to prevent intrusion, and all sorts of other things fire marshals go ballistic over.
It's unfortunate, but it's extremely hard to reconcile these opposing requirements and make a facility both safe and secure.
