What is the maximum distance allowed between visual devices in a corridor?

The maximum distance allowed between visual devices in a corridor is 100 feet. This standard is established to ensure that individuals in a building can quickly and easily identify emergency exits and directions, particularly in low visibility situations such as smoke or darkness.

Maintaining a distance of no more than 100 feet between visual devices, such as exit signs and emergency lights, is critical for effective evacuation during an emergency. This guideline helps facilitate safe navigation through a building and supports the identification of safe egress routes without excessive delay.

In contrast, shorter distances may hinder placement flexibility and not optimize coverage, while longer distances could result in critical gaps where individuals might not be able to see emergency signs, leading to confusion or increased risk during an emergency evacuation.
