What is the primary function of exit signs in building safety?

• A. Exit signs guide to exits
• B. They provide general lighting
• C. They indicate occupancy load
• D. They help with decoration

Answer: (A)

The main idea is that exit signs exist to guide people to safe egress routes. They are designed to point the way to exits, especially when visibility is low or during a power outage, so you can reach an exit quickly and predictably. This is why they’re often continuously illuminated and placed along corridors and above doors that lead outside. Exit signs aren’t meant to provide general lighting for a space, so they should not be relied on for illumination of rooms or halls. They also don’t convey information about how many people can be in the space (occupancy load), nor are they decorative. Their purpose is straightforward: clearly indicate where the exits are to speed and simplify evacuation.
