Emergency lighting is an essential consideration for many buildings, and its provision and proper working can safeguard lives.
BS 5266 gives recommendations and guidance to be taken into account in the design, installation, and wiring of electrical emergency lighting systems in the event of failure of the supply to the normal lighting.
It applies to emergency lighting systems used to assist occupants to leave a building during an emergency, or help protect occupants staying in a building during an emergency and continuing normal operations.
