1. An emergency egress safety system for a door to a protected room, the emergency egress safety system comprising:
a base, the base for straddling an edge of a door and having a first portion for locating on a side of the door facing outside the protected room and a second portion for locating on a side of the door facing the protected room;
an arm mounted relative to the base, the arm being mounted to the base for movement between a stowed position and a deployed position where the arm is extended from the base and is automatically locked in the deployed position to block the door that is straddled by the base;
a locking rod mounted in said base and movable between a non-locking position and a locking position, the locking rod having an engagement surface, when the locking rod is in the locking position the engagement surface is aligned with the arm to block the arm returning to its stowed position and when the locking rod is moved to the non-locking position the engagement surface is no longer aligned with the arm and the alarm is allowed to return to its stowed position;
a first actuator located at the first portion operable to unlock the arm to allow the arm to return to its stowed position, the base having an upper outer side, and the first actuator accessible through said upper outer side, wherein the arm and the first actuator are fully contained within the base when the arm is returned to its stowed position; and
a second actuator operable to unlock the arm to allow the arm to return to its stowed position, the second actuator being fully contained within the base.
