including stairways and exits, shall be marked by lighting or photoluminescent
strip indicators placed not more than 0,3 metres above the deck at all points
of the escape route including angles and intersections. The marking must
enable passengers to identify all the routes of escape and readily identify
the escape exits. If electric illumination is used, it shall be supplied by
the emergency source of power and it shall be so arranged that the failure of
any single light or cut in a lighting strip will not result in the marking
being ineffective. Additionally, all escape route signs and fire equipment
location markings shall be of photoluminescent material or marked by lighting.
The Administration of the flag State shall ensure that such lighting or
photoluminescent equipment have been evaluated, tested and applied in
accordance with the guidelines as given in IMO Resolution A.752 (18).
