Last updated: December 07, 2009

A. General. Building corridors and hallways must remain clear in order to provide safe egress during emergencies. Any time items are placed in corridors or hallways, they must never impede flow of persons entering and/or exiting the building, reduce the access width below minimum requirements, or create a fire hazard situation. Basic university policy is to keep corridors and hallways clear of obstructions regardless of access width. In certain situations, however, with proper approval from Environmental Health and Safety (EHS), certain items may be placed in corridors or hallways without adversely affecting exiting requirements. [ed. 12-09]

A-1. Regulatory Requirements. The legal minimum width of corridors and hallways is determined by the applicable International Building Code, International Fire Code, Life Safety Code, and the Idaho General Safety and Health Standards. [ed. 12-09]

A-2. Unapproved Placement. Items placed in a corridor, hallway, or other path of entry or egress without approval may be subject to immediate removal at the direction of the Environmental Health and Safety Office. The unit responsible for the unapproved item will also be responsible for the cost of removal and any resulting damage. [add. 12-09]

B. Process. Campus units desiring to place objects in corridors or hallways are required to complete and submit a Building Corridor Use Exemption Request Form to EHS. EHS personnel will review the request, inspect the area, and make final a determination as to approval or denial. [rev. 12-09]
