NEBOSH Certificate In Fire Safety – Element 1 Practice Test

What is the purpose of emergency lighting in means of escape?

To illuminate work areas during normal operation. To power the main lighting circuit. To illuminate escape routes if the mains supply fails, enabling safe evacuation. To provide decorative lighting during emergencies.

Correct Answer:

To illuminate escape routes if the mains supply fails, enabling safe evacuation.

Explanation:

Emergency lighting in means of escape is there to ensure that, when the normal power fails, escape routes—like corridors, stairs, exits—and exit signs remain visible so people can evacuate safely. It is powered by a backup source and activates automatically during a mains failure, providing enough light for the required evacuation duration. This function is not about lighting work areas during normal operation, powering the main lighting circuit, or decorative lighting; its purpose is safety and to guide people to safety when the usual lights are out.
