What is the maximum length allowed for a dead-end corridor?

The maximum length allowed for a dead-end corridor is commonly specified in building codes to ensure safe egress and minimize the risks associated with fire and smoke spread. In many jurisdictions, the limit for dead-end corridors is set at 6 meters (approximately 20 feet).

This 6-meter limit is established because longer dead-end corridors can create challenges for occupants attempting to evacuate a building in an emergency. If a corridor extends beyond this length, it may increase the time occupants need to reach an exit, potentially placing them at greater risk during smoke or fire conditions.

In addition to the length restriction, codes may also require that dead-end corridors lead to exit doors that open directly to an exterior area or to a stairway that provides vertical egress. This ensures that occupants can efficiently escape the building, reinforcing the overall principle of life safety within code regulations.
