5.2 Approval documentation for PL materials shall include the minimum level of ambient light necessary to charge the PL material to meet the required luminance as contained in clause 4.2.
6 Installation on board
6.1 General
6.1.1 Positioning of the LLL system and signs shall be arranged to enable persons to readily identify all routes of escape and exits. However, LLL should not be installed in public spaces. In addition, to keep escaping persons from having to cross LLL strips, lighting need not be installed along the door thresholds or across stairway landings.
6.1.2 LLL systems shall be fitted in accordance with the manufacturer's specification. When the LLL system is installed on decks it shall be arranged in such a way that the LLL strips do not constitute a danger for the free circulation of people. Generally, LLL strips should be flush with the carpet or the primary deck covering surface.
When fitted on bulkheads, the arrangement shall be such that the fire integrity of divisions is not impaired.
6.2 Corridors
6.2.1 In all corridors the visual effect of the LLL system shall be continuous, except where interrupted by intersections with other corridors, cabin doors, or local enlargements or recesses, to provide a visible delineation along the escape routes. In way of local enlargements or recesses the maximum interruption permitted in LLL systems shall not exceed 2 m.
6.2.2 LLL systems not formed by continuous lighting strips shall have individual lighting points no greater than 300 mm apart.
6.2.3 The LLL shall be installed on at least one side of the corridor. In corridor more than 2 m wide, LLL shall be installed on both sides. Small individual recesses, less than 2 m long in the line of the corridor or with a combined total length less than 50% of the length of the corridor, shall not be included when calculating the width of a corridor.
6.2.4 The LLL system shall be located either on the bulkhead within 300 mm of the deck, or on the deck within 150 mm of the bulkhead. LLL may be installed at a distance greater than 150 mm from the bulkhead in way of recesses, as shown in annex F, Figure F.1, or where the escape routes cross open spaces, public spaces, lobbies or landings exceeding 4 m in the line of escape. Steps in corridors shall comply with clause 6.4.
6.2.5 In dead-end corridors the LLL system shall include arrows or equivalent direction indicators, at intervals of no more than 1 m, pointing away from the dead end.
6.3 Doors
6.3.1 Doors which form part of the escape route (e.g., doors in stairways, main vertical zone boundaries in corridors), or doors leading to open decks shall be marked by LLL in accordance with this standard. Transparent doors along the escape route need not be marked if they are a swinging type without fixed means for their closure. Where a door is used in both directions as a primary or secondary means of escape (e.g. a door at main vertical zone boundary) it shall be marked on both sides. To prevent confusion only exit doors shall be marked with the LLL.
