Provides recommendations and guidance on the factors that need to be taken into account in the design, installation and wiring of electrical emergency lighting systems, in order to provide the lighting performance needed for safety of people in the building in the event of failure of the supply to the normal lighting.

This part of BS5266 gives recommendations and guidance on the factors that need to be taken into account in the design, installation and wiring of electrical emergency lighting systems, in order to provide the lighting performance needed for safety of people in the building in the event of failure of the supply to the normal lighting. This British Standard applies to emergency lighting systems used to: assist occupants to leave a building during an emergency; help protect occupants if they stay in a building during an emergency; help occupants to continue normal operations in the event of failure of the supply to the normal lighting. This part of BS5266 also gives recommendations for lighting in areas with fixed seating.
