4. Maintenance and inspection of fixed carbon dioxide fire extinguishing system IMO MSC/Circ.1318, paragraph 6.1.2
(1)
Maintenance and inspection plan
Fixed carbon dioxide fire extinguishing systems should be kept in good working
order and readily available for immediate use. Maintenance and inspections should be carried out in accordance with the ship’s maintenance plan having due regard to ensuring the reliability of the system. The onboard maintenance plan should be
included in the ship’s safety management system and should be based on the system manufacturer’s recommendations including:
.1 maintenance and inspection procedures and instructions? .2 required schedules for periodic maintenance and inspections? .3 listing of recommended spare parts? and
.4 records of inspections and maintenance, including corrective actions taken to maintain the system in operable condition.
(2)
Monthly inspections
2.1 At least every 30 days a general visual inspection should be made of the
overall system condition for obvious signs of damage, and should include verification that:
12
.1 all stop valves are in the closed position?
.2 all releasing controls are in the proper position and readily accessible(易接近的) for immediate use?
.3 all discharge piping and pneumatic tubing（输气管） is intact and has not been damaged? .4 all high pressure cylinders are in place and properly secured? and .5 the alarm devices are in place and do not appear damaged.
2.2 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 service valve is secured in the open position? and .4 the vapor supply line valve is secured in the open position.
(3) Annual inspections
The following minimum level of maintenance and inspections should be carried out in accordance with the system manufacturer’s instructions and safety precautions:
.1 the boundaries of the protected space should be visually inspected to confirm that no modifications have been made to the enclosure that have created un-closeable openings that would render the system ineffective;
.2 all storage containers should be visually inspected for any signs of damage, rust. Cylinders that are leaking, corroded, dented or bulging should be hydrostatically retested or replaced;
.3 the manifold should be inspected to verify that all flexible discharge hoses and fittings are properly tightened;
.4 all entrance doors to the protected space should close properly and should 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-sounded.
.5 All remote releasing controls should be checked for clear operating instructions and indication as to the space served.
13
(4) Renewal survey* in cargo ships , the following maintenance should be carried out
.1 all high pressure cylinders and pilot cylinders should be weighed or
have their content 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 refilled. 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 tests 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% of the onboard cylinders should be tested. If further cylinders fail, all cylinders should be tested. Flexible hoses should be replaced at the intervals recommended by the manufacturer and not exceeding every 10 years;
.3 the discharge piping and nozzles should be tested to verify that they are not blocked. The test should be performed by isolating the discharge piping from the system and flowing dry air or nitrogen(氮气)from test cylinders or suitable means through the piping.
5. Controls for fixed carbon dioxide fire extinguishing system
FSS Code, Chapter 5, paragraph 2.2.2
Carbon dioxide systems shall comply with the following requirements: (1) Two separate controls shall be provided for releasing carbon dioxide into a protected space and to ensure the activation of the alarm. One control shall be used for opening the valve of the piping which conveys the gas into the protected space and a second control shall be used to discharge the gas from its storage containers;
(2) Two controls shall be located inside a release box clearly identified for the particular space. If the box containing the controls is to be locked, a key to the box shall be in a break-glass-type enclosure conspicuously located adjacent to the box.
6. Foam fire-extinguishing systems
IACS Recommendation No.53-2
14
IMO MSC/Circ.1312, MSC/Circ.670 and MSC/Circ.798
Fixed foam extinguishing systems should be inspected every two years by a competent service station recognized by a Recognized Organization. Foam sample analysis shall be carried out after a period of 3 years after being supplied to the ship and thereafter every year at authorized service agent of manufacturer’s laboratory. A record of the age of the foam concentrates and of subsequent controls should be kept on board.
7. Air cylinders for self-contained breathing apparatus (SCBA) (CABA) IMO MSC/Circ.850, 1432
IACS Recommendation No.88
SCBA cylinders should be hydraulic pressure tested at intervals not exceeding 5 years and the hydrostatic test date must be permanently marked on the bottles. Two spare charges suitable for use with the breathing apparatus should be provided for each SCBA. If cargo ship are equipped with suitably located means for fully recharging the air cylinders free from contamination, only one spare charge is required for each required SCBA.
8. Air bottles for air supply in totally enclosed lifeboats IACS Recommendation No.88
Air bottles for air supply in totally enclosed lifeboats should be hydraulic pressure tested by a competent service station recognized by a recognized organization at intervals not exceeding 5 years and the hydrostatic test date must be permanently marked on the bottles.
