Emergency lighting is lighting for an emergency situation when the main power supply is lost cut and any normal illumination fails. The loss of mains electricity could be the result of a power cut or fire and the normal lighting supplies fail. This may lead to sudden darkness and a possible danger to the occupants, either through physical danger or panic.
Emergency lighting is normally required to operate fully automatically and give illumination of a sufficiently high level to enable all occupants to evacuate the premises safely. Most new buildings now have emergency lighting installed during construction; the design and type of equipment being specified by the architect in accordance with current building regulations and any local authority requirements.
