For all commercial premises, a functioning fire safety and detection system is vital to remain within the fire regulations, and keep everyone inside the building safe in the event of a fire. An emergency lighting system should be in every office and public building, and provides lighting when the main power supply fails, for example from a power outage or a fire. The loss of mains electricity in the event of a fire could prove fatal without the backup option of emergency lighting, as it enables people in the building to safely evacuate the premises.
Emergency lighting uses an independent power source from mains power, ensuring that it will come into effect in any event if the mains power is shut off. They can be in the form of an exit sign over a fire exit door, to LED lights on the floor acting as a pathway to fire exits in the case of an evacuation.
