There are also additional requirements where the door is the final exit point of a building:
The door should open in the direction of evacuation.
There should be no locks or catches. Many use a push bar system that will open the door when pressed down. If the door is also a secure entrance, the lock/catches must self-open when the fire alarm sounds.
The final fire exit door must lead to a place of safety.
It must have a self-closing mechanism so that the door will shut behind people evacuating in order to contain the fire and smoke. This will also limit the oxygen going in to the building which will feed a fire.
The signage will need mandatory fire exit signs that are illuminated. Situated above the door.
