Horizontal Exits [IBC §1021 (2003), §1005.3.5 (2000)]

A horizontal exit compartmentalizes a building allowing occupants to exit the area containing the origin of a fire into another portion of the building that is protected by fire-resistance-rated assemblies (doors, walls, ceilings, and floors). A horizontal exit separates a space into two exit access areas. IBC requirements for horizontal exits address fire-rated separation, opening protectives, capacity, and other features.
