SUB-COMMITTEE ON DANGEROUS GOODS, SOLID CARGOES AND CONTAINERS
18th session
Agenda item 6
DSC 18/6/1
7 March 2013 Original: ENGLISH
DEVELOPMENT OF AMENDMENTS TO THE IMSBC CODE AND SUPPLEMENTS, INCLUDING EVALUATION OF PROPERTIES OF SOLID BULK CARGOES
Outcome of MEPC 64 and FP 56
Note by the Secretariat
I MPLEMENTATION OF REVISED MARPOL A NNEX V
1 The Sub-Committee, at its seventeenth session, with regard to the implementation of the revised MARPOL Annex V, considered the views of the E&T 17 (DSC 17/4/2) that the development of a new section for environmentally hazardous substances is necessary within the IMSBC Code, together with document DSC 17/4/9 (Canada), suggesting that including a list of solid bulk materials in the Code, which fall under the revised MARPOL Annex V, could be helpful and expressing their concern over the difficulty of implementing the revision of MARPOL Annex V. Having noted that MEPC 64 would consider the above matters in relation to the revised MARPOL Annex V, DSC 17 agreed, in general, to have a new section in the future IMSBC Code relating to the revised MARPOL Annex V.
2 MEPC 64 instructed the Sub-Committee to consider how the long-term implementation of the provisions of MARPOL Annex V, concerning cargo residues, could be facilitated by amendments to the IMSBC Code.

3 In this context, MEPC 64, having considered the report of the drafting group (MEPC 64/WP.13), agreed to the provisional classification of solid bulk cargoes under the revised MARPOL Annex V (MEPC.1/Circ.791).
F IRE EXTINGUISHIN
G ARRANGEMENTS IN CARGO SPACES (IMSBC C ODE)
4 FP 56 noted that DSC 17 had forwarded a draft interpretation to the IMSBC Code on fire-extinguishing arrangements in cargo spaces (DSC 17/WP.5, annex 6) to FP 56 for its expert consideration and advice to DSC 18.
5 In this regard, FP 5
6 noted that DSC 1
7 had deleted the last sentence of the IACS Unified Interpretation SC 250 (DSC 17/4/1/Rev.1, annex), which was used as the basis for the draft interpretation agreed at the session, on fixed gas fire-extinguishing systems or inert gas systems dedicated for the protection of spaces other than cargo spaces that should not be used for the purposes of preventing the consequences of self-heating of certain solid bulk cargoes.
6 In this connection, FP 56 concluded that the addition of the word "exclusively" after "dedicated" in the last sentence of IACS Unified Interpretation SC 250, would exclude from the text of the interpretation those fixed gas systems which are intended to protect just one space (e.g. engine-room), thus removing any ambiguities, and agreed that the sentence should be reinstated, as modified, in the text of the interpretation prepared at DSC 17. The FP Sub-Committee invited DSC 18 to consider the above view and take action accordingly.
