Instructions for inspection of Low Location Lighting -LLL

Translation of circular no 5 – Serie 1. Case no: A-01/05804 OAA/IKH from the Norwegian Maritime Directorate. In force: 31.12 + 5 years. Cancels all previous circulars and instructions. [In Norwegian]

Norwegian Maritime Directorate will remind you that according to regulations 28.1.10 of SOLAS chapter II-2 all new passenger ships that are covered by the Sea safety convention must be fitted with Low Location Lighting in all escape routes.

The Low Location Lighting being either photoluminescent (PL) or electrically powered (EP), shall indicate the direction of the escape routes in the event of smoke or absence of light.

The regulations above have also been put into force for new passenger ships(24 meters long and above, that is ships covered by the EU directive 98/18). Refer also to regulation 6.7 chapter II-2, Part B in appendix I to Regulations regarding control, building and outfitting of passenger ships in Norwegian waters of 1.March 2000 (Circular F no. 9/2000).

For existing ships the regulations regarding LLL was enforced from 1.October 1997. The regulations includes both passenger and crew corridors.

The new Fire Safety System Code - FSS - code, which is laid down by MSC and effective from 1.July 2002 and is referred to in the revised issue of SOLAS chapter II-2, makes reference to both IMO Res. A.752(18) and ISO-standard 15370 Ships and marine technology - Low location lighting on passenger ships with regard to testing and installation of the LLL- systems.

IMO Res. A.752 (18) does not specify procedures for testing on board.
Norwegian Maritime Directorate will therefore in the future demand that the test methods described in the ISO standard 15370 shall be applied even though no reference is made to this standard in today's version of SOLAS chapter II-2 Regulation 28.1.10.

According to IMO Res. A.752 (18) point 9.1 the LLL system shall be visually inspected on board at least once every week. The inspection shall be registered. This inspection must be included in the ship's maintenance systems.

Furthermore, IMO Res. A. 752(18) point 9.2 demands testing of the luminance levels of the system every 5 years.

The ISO standard recommends yearly testing on one deck in the vertical main zone.

Norwegian Maritime Directorate will on this point follow the IMO regulations and demand testing every 5 years of the photoluminescent material unless there has not been reconstruction or rebuilding that may have had an effect on the Low Location Lighting in a specific area.

Norwegian Maritime Directorate therefore asks the local stations to be aware of this when onboard inspections are carried out. If the 5 years testing according to IMO Res. A.752(18) point 9.2 has not been observed this must immediately be reported and a new Safety Certificate must not be issued.

It is important that the measurements are being carried out in a correct way both regarding procedures and equipment.

Norwegian Maritime Directorate can therefore only accept measurements performed by companies which satisfies international standards with regard to this type of field measurements, for instance ISO or DIN or EU norms EN 45001, EN 45004 or IACS Z 17.

Companies performing measurements must hold a certificate from a well-known classification society or a technical controlling body that shows that the company is competent to carry out such field measurements.
Enclosed please find for your information IMO Res. A.752(18) and the draft ISO standard 15370.

The enclosed ISO standard is now a so-called ISO/FDIS (final draft international standard) document which means that the document is to be considered as an interim approved standard. The ISO standard 15370 is expected to be finally approved at yearend 2001/02.
