20 2 / 24 QC-T-261 SC 218 Fire Testing of Equivalent Water-Based Fire Extinguishing Systems (IMO MSC/Circ.1165, Appendix B, 4.5.1) (Oct 27) Regulation (IMO MSC/Circ.1165, Appendix B, 4.5.1) 4.5 Procedure The trays used in the test should be filled with at least 5 mm fuel on a water base. Freeboard is to be 15 mm ± 1 mm.

21 21 / 24 QC-T-261 It has been recognized that this cannot be achieved for the 3 m2 top tray as the total height of this particular tray is only 1 mm. The freeboard requirement of 15 mm applies consequently only to the.1 m2,.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 this tray shall be 5 mm. SC 219 Fire Testing of Equivalent Water-Based Fire Extinguishing Systems (IMO MSC/Circ.1165, Appendix B, ) (Oct 27) Regulation (IMO MSC/Circ.1165, Appendix B, ) Duration of test After ignition of all fuel sources, a 2-min preburn time is required before the extinguishing agent is discharged for the fuel tray fires and 5-15 s for the fuel spray and heptane fires and 3 s for the Class A fire test (Test No.7). For flowing fire (Test No. 6), the 4 m 2 fire tray below the engine mock-up should be filled with a 5 mm water base and the 3 m 2 fire tray on top of the engine mock-up should be filled with a 4 mm water base. The fuel should be ignited when flowing down the side of the mock-up, approximately 1m below the notch. The pre-burn time should be measured from the ignition of the fuel. SC 221 Separation of Galley Exhaust Ducts from Spaces (Reg II-2/9) (Oct 27) Reg. II-2/ reads: The ventilation systems for machinery spaces of category A, vehicle spaces, ro-ro spaces, galleys, special category spaces and cargo spaces shall, in general, be separated from each other and from the ventilation systems serving other spaces. Except that the galley ventilation systems on cargo ships of less than 4, gross tonnage and in passenger ships carrying not more than 36 passengers, need not. except that penetrations of main zone divisions shall also comply with the requirements of paragraph Reg. II-2/ reads: Ducts provided for ventilation to accommodation spaces, service spaces or control stations shall not pass through machinery spaces of category A, galleys, vehicle spaces, ro-ro spaces or special category spaces unless they comply with the conditions specified in paragraphs to or and below:. except that penetrations of main zone divisions shall also comply with the requirements of paragraph Reg. II-2/ reads: Where they pass through accommodation spaces or spaces containing combustible materials, the exhaust ducts from galley ranges shall be constructed of "A" class divisions. Each exhaust duct shall be fitted with:...4 fixed means for extinguishing a fire within the duct. With respect to the application of SOLAS regulations II-2/ , and for determining fire insulation for trunks and ducts which pass through an enclosed space, the term pass through pertains to the part of the trunk/duct contiguous to the enclosed space.

II-2/13.1 Purpose The purpose of this regulation is to provide means of escape so that persons on board can safely and swiftly escape to the lifeboat and liferaft embarkation deck. For this purpose, the following functional requirements shall be met:.1 safe escape routes shall be provided;.2 escape routes shall be maintained in a safe condition, clear of obstacles; and.3 additional aids for escape shall be provided as necessary to ensure accessibility, clear marking, and adequate design for emergency situations.

23 23 / 24 QC-T-261 To facilitate a swift and safe means of escape to the lifeboat and liferaft embarkation deck, the following provisions apply to overhead hatches fitted along the escape routes addressed by Reg. II-2/13: 1. the securing devices shall be of a type which can be opened from both sides; 2. the maximum force needed to open the hatch cover should not exceed 15 N; and 3. the use of a spring equalizing, counterbalance or other suitable device on the hinge side to reduce the force needed for opening is acceptable. SC 25 Fire-Extinguishing Arrangements in Cargo Spaces (Res. MSC.268(85), IMSBC Code) (Oct 211) For certain individual schedules of solid bulk cargoes in Appendix 1 of the IMSBC Code as amended, such as FISHMEAL (FISHSCRAP) STABILIZED UN 2216, SEED CAKE, containing vegetable oil UN 1386, SEED CAKE UN 2217, the following ventilation requirement is present: QUOTE If the temperature of the cargo exceeds 55 C and continues to increase, ventilation to the cargo space shall be stopped. If self-heating continues, then carbon dioxide or inert gas shall be introduced to the cargo spaces UNQUOTE This self-heating phenomenon shall be regarded as an emergency condition such that it is not necessary to provide a separate fixed carbon dioxide fire-extinguishing system or inert gas system dedicated to the control of the 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 Safety Systems Code required by SOLAS Regulations II-2/ or II-2/1.7.2 may be used for this purpose. Fixed gas fire-extinguishing systems or inert gas systems installed on board to protect spaces other than cargo spaces cannot be used for this purpose. Note: 1. This Unified is to be uniformly implemented by IACS Societies from 1 July 212. SC 253 Fire resistance requirements for fibre-reinforced plastic (FRP) gratings used for safe access to tanker bows (IMO Res.
