UNIFIED INTERPRETATION TO SOLAS CHAPTER II-2
AND RELATED FIRE TEST PROCEDURES
Draft Guidelines for approval of flame detectors for the automatic activation of the fixed local application fife-fighting system
Submitted by Japan
SUMMARY
Executive summary: This document describes matters of an interpretation
to SOLAS chapter II-2 regulation 10.5.6.2 and a related draft guidelines for approval of flame detectors
for the automatic activation of the fixed local application fire-fighting system.
Action to be taken: Paragraph 8

1 Amendments to chapter II-2 of SOLAS 74 were adopted at MSC 73 by resolution MSC.99(73), as set out in annex 7 to document MSC 73/21/Add.2. Regulation 10.5.6.2 of the revised SOLAS chapter II-2 has a requirement that, in case of periodically unattended machinery spaces, fixed local application fire-fighting systems shall have both automatic and manual release capabilities.
2 The fixed local application fire-fighting system shall be activated for a local fire started at a high fire risk area as mentioned in regulation 10.5.6.3 of chapter II-2 of SOLAS 74, as amended. In order to activate the system promptly and correctly to the area of fire, accurate and quick detection and identification of such a local fire are quite important.
3 However, smoke detectors and heat detectors used in machinery spaces wildly today could not, in general, identify the area of local fire due to large and high speed air flow within the machinery space.
4 On the other hand, flame detection systems can be used for detecting and identifying area of the local fire regardless the air flow within the machinery space.
5 Japan thinks that such a flame detector is useful and that guidelines for approval of flame detectors are necessary. It has been recognized that a European standard for flame detectors is being developed (prEN 54-10).
6 Therefore, Japan decided to develop draft guidelines for approval of flame detectors used in machinery spaces of ships upon a consultation with manufacturers, users (ship yards, ship owners and operators) and fire safety specialists having due regard to the draft European standard and possible additional requirements for robustness against marine environmental conditions. The draft guidelines are still in the development stage and not yet finalized.
7 It may be possible to ask ISO/TC 8 to develop an international standard of flame detectors for marine use. In such a case, Japan will be delighted to offer the draft to ISO/TC 8 as a basis of developing such an international standard.
Action requested of the Sub-Committee
8 The Sub-Committee is invited to take note the development in Japan of guidelines for approval of flame detectors and take actions as appropriate.
