Escape Route Lighting (Previously called Defined Escape Routes)
Open Area Lighting (Anti Panic)
Emergency Escape Lighting
High Risk Task Area Lighting
Low mounted way guidance systems are intended to complement 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 Lighting BS 5266pt 7/EN 1838 4.1
Identification of Exit and Escape Routes
• Signs complying with the Signs Directive are required at all emergency Exits and along Escape routes
• Where direct sight of a sign is not possible a directional sign or series of signs must be used
• There should be no ambiguity as to which direction the escape route follows
Safety Signs Format Note format of pictogram signs should not be mixed - EN 50172

1990
1996
Should have been replaced by 24 December 1998
BS 5499 Guides identify that this format also Complies with Signs Directive
• Luminance of the green shall be at least 2cd/m2 • Ratio of max. to min. luminance shall be less than 10:1 • Colours shall be as ISO 3864 i.e. White out of Green Kite marked Luminaires to EN 60598-2-22 are checked to be compliant
For escape routes up to 2m in width, the horizontal illuminances on the floor along the centre line of an escape route shall not be less than 1 lux and the central band consisting of not less than half of the width of the route shall be illuminated to a minimum of 50% of that value
