Regulation (IMO MSC/Circ.1165, Appendix B, 4.5.1)4.5 Procedure4.5.1 The trays used in the test should be filled with at least 50 mm fuel on a water base.Freeboard is to be 150 mm ± 10 mm.

Interpretation





21 / 24 QC-T-261

QF-K-05 2003-03

It has been recognized that this cannot be achieved for the 3 m2 top tray as the total height of this particular trayis only 100 mm.The freeboard requirement of 150 mm applies consequently only to the 0.1 m2, 0.5 m2, 2.1 m2 and 4 m2 tray(see IMO MSC/Circ.1165, Appendix B, Figure 1).Freeboard in the 3m2 top tray measured from heptane level (which is same as top of notch) to the top of thistray shall be 50 mm.

SC 250 Fire-Extinguishing Arrangements in Cargo Spaces(Res. MSC.268(85), IMSBC Code)(Oct 2011)

For certain individual schedules of solid bulk cargoes in Appendix 1 of the IMSBC Code as amended, such asFISHMEAL (FISHSCRAP) STABILIZED UN 2216, SEED CAKE, containing vegetable oil UN 1386, SEEDCAKE UN 2217, the following ventilation requirement is present:QUOTEIf the temperature of the cargo exceeds 55°C and continues to increase, ventilation to the cargo space shall bestopped. If self-heating continues, then carbon dioxide or inert gas shall be introduced to the cargo spacesUNQUOTE

InterpretationThis self-heating phenomenon shall be regarded as an emergency condition such that it is not necessary toprovide a separate fixed carbon dioxide fire-extinguishing system or inert gas system dedicated to the control ofthe self-heating of the cargo within the cargo holds.The fixed carbon dioxide or inert gas fire-extinguishing system complying with the provisions of the Fire SafetySystems Code required by SOLAS Regulations II-2/10.7.1.3 or II-2/10.7.2 may be used for this purpose. Fixedgas fire-extinguishing systems or inert gas systems installed on board to protect spaces other than cargo spacescannot be used for this purpose.
