Emergency lighting is designed to deal with the provision of lighting in the event of an emergency situation when the main power supply is lost and normal illumination fails which could result in potential danger to the premises occupants.
Emergency lighting is normally required to operate fully automatically and provide sufficient high level of illumination to enable all occupants to evacuate the premises safely.
The British Standard provides the emergency lighting designer with clear guidelines to work to. BS 5266-1 embraces all manner of premises, both commercial, educational, sporting arenas, leisure facilities, shops, hospitals and nursing homes, in fact anywhere that the general public frequent.
Emergency is generally sub-divided into emergency escape lighting and standby lighting.
Emergency escape lighting – a system that provides illumination for the safety of people leaving a location or attempting to terminate a potentially dangerous process beforehand.
Standby lighting– a system enabling normal activities to continue substantially unchanged.
Escape route lighting – an emergency escape system designed to ensure that the means of escape can be effectively identified and safely used by occupants of the building.
