Why is emergency lighting required in building egress?

• A. To provide general illumination for non-emergency use.
• B. To mark decorative features along corridors.
• C. To illuminate exit routes during power outages, ensuring safe movement to exits.
• D. To meet energy efficiency targets unrelated to safety.

Answer: (C)

Emergency lighting is required to illuminate exit routes during power outages, ensuring safe movement to exits. When normal lighting fails, people must still be able to see stairs, corridors, doors, and exit signs to find and reach an exit without tripping or getting lost. The backup lights create a visible path and keep exit signs legible, supporting orderly and safe egress. This isn’t about general illumination for everyday use, decorative features, or meeting energy targets that don’t address safety during outages. The focus is on maintaining a reliable, clearly lit route to safety when the power goes out.
