6.1 For escape routes up to 2 m in width, the horizontal illuminance on the floor along the
centre line of an escape route shall not be less than 1 lx 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.

provided with open area (anti-panic) lighting.

escape route shall not be greater than 40 : 1.
NOTE: To prove the ratio a grid system should be used according to CIE S 015, chap.
