Low Location Lighting
As identified in SOLAS, Chapter II-2, Regulation 188.8.131.52.1 to 184.108.40.206.2 and Chapter II-1, Regulation 42 and 42-1 as appropriate, ships carrying passengers shall be fitted with electric or photoluminescent Low Location Lighting and if carrying more than 36 passengers these regulations also apply to the crew accommodation.
Reference should also be made to IMO Resolution A.752 (18) for the evaluation, testing and application of Low Location Lighting.
LLL System requirements
The system should be installed in accordance with the Fire Systems Safety Code.
If required by legislation then all escape routes, including stairs, must be marked by Low Location Lighting.
Where a photoluminescent material is used this should be a minimum of 75mm wide, unless the photoluminescent performance is increased to allow a narrower width as is the case with the Maritime Progress systems.
Reference should be made to ISO 15370 Annex D as amended, for required performance at reduced widths. The strip should be positioned no higher than 300mm from deck level.
Where stairs or corridors are more than 2m wide, LLL strips should be provided on both sides. Stairs should have the top and bottom clearly identified with signs 2384 or 2385 applied to the strip.
'Dead end' passages should be marked with arrow signs 2382 or 2383 spaced no more than 1m apart to direct people away from the dead end.
The photoluminescent strip should be run up vertically to the handle of each door which forms part of the escape route. 'Exit' signs 2386 or 2387 should be provided at each exit, located on the same side as the door handle. Fire and watertight doors should be marked to show how the door opens.
All photoluminescent material must produce at least 15 mcd/m2 for 10 minutes after removal of external light sources, and at least 2 mcd/m2 after 60 minutes, when tested in situ. The installer should ensure that sufficient light is available to activate the photoluminescent material to attain this performance.
Systems should have their luminescence tested at least once every 5 years.
