What type of hinge is required for an egress door?

An egress door is required to have a specific type of hinge that facilitates quick and easy exit in an emergency situation. Side-hinged doors are the most common choice for egress applications because they allow for a wide opening, making it easier for occupants to exit quickly in the event of a fire or other emergency. This design also helps to maintain the structural integrity of the door frame, ensuring that it opens outward without obstruction, which is crucial in an emergency.

The other types of hinges mentioned do not provide the same kind of efficient access for egress. Top-hinged doors may limit the space for an exit, and bottom-hinged doors could obstruct a clear path. Double-hinged doors, while potentially usable, are not a standard requirement for egress, as they may also complicate the exit process if they do not swing open fully in the necessary direction. Therefore, side-hinged doors remain the preferred choice for ensuring safety and compliance with building codes related to egress.
