Luminaires should be provided along each passageway and

escape route so that there are no dark areas, especially on

stairs and landings and at emergency doors. In the UK, an

illumination level of at least 1 Lux should be provided along the

centre line of general-use escape routes. In open areas larger

than 60m2, an illumination level of 0.5 Lux anywhere in the

core area is the minimum; and for permanently unobstructed

routes, 0.2 Lux minimum on the centre line.
