When illumination of exits is required, it must be continuous during occupancy and floors must be illuminated at not less than 1 foot candle measured at the floor. Which location is specified?

• A. Floor
• B. Ceiling
• C. Wall
• D. Ceiling and Floor

Answer: (A)

The emphasis is on floor-level illumination for safe egress. The rule requires at least 1 foot-candle of illumination measured at the floor, which means you evaluate and ensure lighting where people actually walk. That makes the floor the location specified. Lighting the floor ensures you can see the walking surface, steps, and obstacles during occupancy, especially when exiting. Lighting on the ceiling or walls wouldn’t guarantee this floor visibility, so the floor is the essential location referenced.
