90 minute doors are required when building code requires a 90 minute or 2 hour assembly rating. For example, with IBC '06, 715.4, if a 2 hour wall is required, you can have a 90 minute door. The fire resistance rating depends on the type of building occupancy and component. For example, for fire barrier assemblies or horizontal assemblies, for occupancy of type A (Assembly), B (Business), E, F-2, H-4, H-5, I, M (Merchantile), R, S-2, the fire rating is 2 hours. For other types, say U (Utility) the rating is 1 hour and for H-1 and H-2 (High Hazard) its 4 hours. Since the issue is complex, consult an architect to determine a specific application.

Technically, a "fire exit door" is any door that leads to an exit discharge. Not all fire exit doors are required to have a fire rating or panic hardware or an out-swinging hinge. However, many fire exit doors are fire rated, meaning that they are expected to endure at least some amount of fire for a limited time. Also, some types of occupancies cannot have in-swinging doors anywhere in the egress path. In the US, they are often made of wood or metal. Sometimes they are part of a firewall that is part of a fire rated corridor, and have a rating (such as 1-hour). Rated doors are solid wood or mineral filled metal doors, and are rated by a special agency. An important part of exit doors are the direction of swing and special hardware that allows use in case of panic. Panic hardware for buildings with a large exit load includes a bar near waist height that unlocks the door when pressed from the inside. Some exit panic hardware has a built-in delay for security reasons. Doors made of aluminum and glass are often used at the front of stores and offices. Glass used in a rated fire door assembly must also be fire rated.

Fire rated doors are commonly used in exits from one compartment of a structure to another, and in stairways, to secure the exits. They stop the spread of fire from penetrating beyond the fire rated doors. Therefore, when used along stairways, it allows people to safely evacuate a structure in case of a fire.
