Final answer:
In building codes, dead-end corridors should not exceed a certain length to ensure safe evacuation during emergencies.
Step-by-step explanation:
In building codes, when more than one exit or exit access doorway is required, the exit access must be arranged so that dead-end corridors do not exceed a certain length. This is to ensure that occupants can easily and safely evacuate the building in case of an emergency.
The specific length requirement may vary depending on the jurisdiction and building type, but a common rule is that dead-end corridors should not exceed 20 feet in length.
This regulation helps to minimize the risk of people getting trapped in a dead-end corridor during an emergency, allowing for quick and efficient evacuation.
