13、bon dioxide fire-extinguishing systems, as set out in the annex.2 Member Governments are invited to apply the annexed Guidelines when inspecting fixed carbon dioxide fire-extinguishing systems on board all ships and bring them to the attention of ship designers, shipowners, equipment manufacturers,
14、and other parties concerned.*I:CIRCMSC011318.docMSC.1/Circ.1318ANNEXGUDELINES FOR THE MAINTENANCE AND INSPECTIONS OF FIXED CARBON DIOXIDE FIRE-EXTINGUISHING SYTEMS1 GeneralThese Guidelines provide the minimum recommended level of maintenance and inspections for fixed carbon dioxide fire-extinguishin
15、g systems on all ships, and are intended to demonstrate that the system is kept in good working order as specified in SOLAS regulation II-2/14.2.1.2. These Guidelines are intended to supplement the fire-extinguishing system manufacturers approved maintenance instructions. Certain maintenance procedu
16、res and inspections may be performed by competent crewmembers, while others should be performed by persons specially trained in the maintenance of such systems. The onboard maintenance plan should indicate which parts of the recommended inspections and maintenance should be completed by trained pers
17、onnel.2 SafetyWhenever carbon dioxide fire-extinguishing systems are subjected to inspection or maintenance, strict safety precautions should be followed to prevent the possibility that individuals performing or witnessing the activities are placed as risk. Prior to performing any work, a safety pla
18、n should be developed to account for all personnel and establish an effective communications system between the inspection personnel and the on-duty crew. Measures to avoid accidental discharges such as locking or removing the operating arms from directional valves, or shutting and locking the syste
19、m block valve should be taken as the initial procedure for the protection of personnel performing any maintenance or inspections. All personnel should be notified of the impending activities before work is begun.3 Maintenance and inspection planFixed carbon dioxide fire-extinguishing system should b

Maintenance and inspections should be carried out in accordance with the ships maintenance plan having due regard to ensuring the reliability of the system. The onboard maintenance plan should be included in the ships safety manag

23、on that:.1 all stop valves are in the closed position;.2 all releasing controls are in the proper position and readily accessible for immediate use;.3 all discharge piping and pneumatic tubing is intact and has not been damaged;.4 all high pressure cylinders are in place and properly secured; and.5
24、the alarm devices are in place and do not appear damaged.4.2 In addition, on low pressure systems the inspections should verify that:.1 the pressure gauge is reading in the normal range;.2 the liquid level indicator is reading within the proper level;.3 the manually operated storage tank main servic

26、aries of the protected space should be visually inspected to confirm that no modifications have been made to enclosure that have created uncloseable openings that would render the system ineffective;.2 all storage containers should be visually inspected for any signs of damage, rust or loose mountin
27、g hardware. Cylinders that are leaking, corroded, dented or bulging should be hydrostatically retested or replaced;.3 System piping should be visually inspected to check for damage, loose supports and corrosion. Nozzles should be inspected to ensure they have not been obstructed by the storage of sp
28、are parts or a new installation of structure or machinery;.4 the manifold should be inspected to verify that all flexible discharge hoses and fittings are properly tightened; andI:CIRCMSC011318.docMSC.1/Circ.1318ANNEXPage 3.5 all entrance doors to the protected space should close properly and should
29、 have warning signs, which indicate that the space is protected by a fixed carbon dioxide system and that personnel should evacuate immediately if the alarms sound. All remote releasing controls should be checked for clear operating instructions andindication as to the space served.6 Minimum recomme
30、nded maintenance6.1 At least biennially (intervals of 2 years 3 months) in passenger ships or at each intermediate, periodical or renewal survey in cargo ships, the following maintenance should be carried out (to assist in carrying out the recommended maintenance, examples of service charts are set
31、out in the appendix):.1 all high pressure cylinders and pilot cylinders should be weighed or have their contents verified by other reliable means to confirm that the available charge in each is above 90% of the nominal charge. Cylinders containing less than 90% of the nominal charge should be refill
32、ed. The liquid level of low pressure storage tanks should be checked to verify that the required amount of carbon dioxide to protect the largest hazard is available;.2 the hydrostatic test date of all storage containers should be checked. High pressure cylinders should be subjected to periodical tes
33、ts at intervals not exceeding 10 years. At the 10-year inspection, at least 10% of the total number provided should be subjected to an internal inspection and hydrostatic test*. If one or more cylinders fail, a total of 50% the onboard cylinders should be tested. If further cylinders fail, all cylin
34、ders should be tested. Flexible hoses should be replaced at the intervals recommended by the manufacturer and not exceeding every 10 years; and.3 the discharge piping and nozzles should be testes to verify that they are not blocked, The test should be performed by isolating the discharge piping from
35、 the system flowing dry air or nitrogen from test cylinders or suitable means through the piping.6.2 At least biennially (intervals of 2 years 3 months) in passenger ships or at each renewal survey* in cargo ships, the following maintenance should be carried out by service technicians/specialists tr
36、ained to standards accepted by the Administration:.1 where possible, all activating heads should be removed from the cylinder valves and tested for correct functioning by applying full working pressure through the pilot lines.In cases where this is not possible, pilot lines should be disconnected fr
37、om the cylinder valves and blanked off or connected together and tested with full working pressure from the release station and checked for leakage.In both cases this should be carried out from one or more release stations when installed.*RefertoSurveyguidelinesundertheHarmonizedSystemofSurveyandCer

If the remote release controls are operated by pneumatic pressure, the tubing should
40、 be checked for leakage, and the proper charge of the remote releasing station pilot gas cylinders should be verified. All controls and warning devices should function normally, and the time delay, if fitted should prevent the discharge of gas for the required time period; and.3 after completion of
41、the work, the system should be returned to service. All releasing controls should be verified in the proper position and connected to the correct control valves. All pressure switch interlocks should be reset and returned to service. All stop valves should be in the closed position.MSC.l/Circ.1318AN
