Emergency Lighting Systems
Emergency Lighting Standard – I.S. 3217:2023
Emergency lighting is required when the main power supply is cut and any normal illumination fails. This may be a result of a fire, or a power cut and the normal lighting supplies fail. Sudden darkness is a possible danger to the occupants, either through physical danger or panic, to exit the premises safely.
What is emergency lighting?
- Emergency escape lighting – the part of an emergency lighting system that provides light for the safety of people leaving a location or attempting to terminate a potentially dangerous process beforehand.
- Escape route lighting – the part of an emergency escape lighting system provided to ensure that the means of escape can be effectively identified and safely used by occupants of the building.
- Open area lighting – the part of an emergency escape lighting system provided to minimise panic and ensure there is sufficient illumination to allow the occupants of a building to reach a place where an escape route can be identified.
