Exit signs must be illuminated and visible from which point?

Exit signs play a crucial role in life safety by guiding occupants to a safe exit during an emergency. The correct focus is on their visibility specifically from the exit access, which refers to the path individuals take to reach an exit. This ensures that as people move through potentially confusing or hazardous areas, they can easily locate the exit signs that will lead them to safety.

Being illuminated and visible from the exit access is essential because it provides clear guidance in instances of smoke, power loss, or other emergencies where visibility may be impaired. By positioning these signs to be easily seen from the places where occupants may be located on their way to the exit, the functionality of the signs is maximized, promoting a swift and safe evacuation.

This specification supports compliance with safety codes and standards, ensuring a well-coordinated response during emergencies. It highlights the importance of strategically placing exit signs along the evacuation routes to maintain awareness of possible escape routes.
