Where should emergency lighting and exit signs be positioned to aid safe egress during a power outage?

• A. On every wall, regardless of path.
• B. Only near the assembly point.
• C. Only above doors that are not used for egress.
• D. Along predefined egress routes.

Answer: (D)

The main idea is to guide people along a known, safe route to an exit when power is out. Emergency lighting and exit signs should be placed along predefined egress routes so the path to the nearest exit stays visible and clearly marked from any point along the route. This keeps directional cues consistent at corridors, intersections, stairs, and doorways, ensuring a person can follow the path without getting lost.

Placing signs on every wall can clutter visibility and may not reflect the actual, safest path to an exit. Signage only near the assembly point doesn’t help someone who is elsewhere in the building, and signs above doors that aren’t used for egress don’t guide you toward a way out. By lining signs and lights along the actual route people should take, you provide reliable guidance to safety.
