Exits and egress paths shall be well marked with illuminated signage as well as emergency lighting sufficient to facilitate an orderly evacuation in the event of a power failure.

This means that in a building or structure, the exits and paths leading to them must be clearly and visibly marked with signs that are illuminated, even in low-light or no-light situations. Additionally, emergency lighting must be present to provide enough light for people to safely and efficiently evacuate the area in case of a power outage or other emergency situation. The goal is to ensure that everyone can quickly and easily find their way to safety in the event of an emergency.
