Emergency Lighting Is Needed:EN 50172 - 4.1

To indicate clearly and unambiguously the escaperoutes

To provide illumination along such routes to allowsafe movements towards and through the exits

provided To ensure that fire alarm call points and fire fighting

equipment provided along escape routes can bereadily located and used

To permit operations concerned with safetymeasures

Low mounted way guidance systems are intended tocomplement emergency escape lighting systems and can only

be used as stand alone systems when they meet all the

relevant recommendations of BS 5266pt7/EN 1838

Illumination For Escape Route LightingBS 5266pt 7/EN 1838 4.1

Identification of Exit and Escape Routes

Signs complying with the Signs Directive arerequired at all emergency Exits and along Escape

routes

Where direct sight of a sign is not possible adirectional sign or series of signs must be used

There should be no ambiguity as to which directionthe escape route follows
