In an emergency, corridors must allow for rapid movement of personnel to evacuate safely. Reduced widths or obstructions can become an impediment.
Lighted EXIT signs are installed throughout the facility to identify exits for emergency evacuation. These signs are illuminated and will operate from emergency power if building electrical systems fail.

How You Can Help
Never obstruct or block exit doors or exit signage!
It is important to not place anything within the exit path or anywhere that might reduce the width or doorways or corridors. Always maintain three feet of egress in corridors and at doors. Never place anything in corridors without specific approval.
Never block open a fire door or place any object nearby that might interfere with the door closing properly.
EXIT signs should never be covered or obstructed so that they are available during an emergency. If signs appear damaged, or if they are not illuminated, contact Facilities immediately for repair.
