Which emergency measure relates to lighting to aid evacuation when required?

• A. Audible Sirens
• B. Emergency Lighting
• C. Exit Signage
• D. Smoke Alarms

Answer: (B)

Emergency lighting provides illumination specifically for escape routes so people can evacuate safely when the normal lighting fails or isn’t available. It automatically activates during a power loss and gives enough light to see doors, stairs, and corridors, guiding occupants to exits and reducing confusion or trips in an evacuation. The other measures serve different roles: audible sirens warn that an emergency is occurring, exit signage shows direction but relies on lighting to be visible, and smoke alarms detect smoke rather than aid visibility. So emergency lighting is the measure that directly relates to lighting to aid evacuation.
