What is the role of a standby power light in a high-rise building during an emergency?

The role of a standby power light in a high-rise building during an emergency is primarily to illuminate dark areas for escaping. In situations where power may be lost due to a fire or other emergencies, these lights provide critical visibility to occupants as they navigate their way to safety. Having adequate lighting is essential for guiding individuals towards exits and away from potential hazards, thereby facilitating an orderly evacuation.

Standby power lights are designed specifically to turn on automatically when a building's main power supply fails. This feature ensures that escape routes, hallways, and stairwells remain illuminated, reducing the risk of panic and confusion during an emergency evacuation.

Other responsibilities, like powering elevators, indicating fire alarm status, or maintaining HVAC functionality, will depend on different systems or equipment specifically designed for those functions, but the immediate focus of standby power lighting is on ensuring safe egress.
