concentrate remain factory sealed, and the manufacturer's recommended service life interval has not been exceeded;
.3 portable containers or portable tanks containing foam concentrate,
excluding protein蛋白质 based concentrates, less than 10 years
old, that remain factory sealed can normally be accepted without the periodical foam control tests required in MSC.1/Circ.1312 being carried out;
32
.4 protein based foam concentrate portable containers and
portable tanks should be thoroughly checked and, if more than five years old, the foam concentrate should be subjected to the periodical foam control tests required in MSC.1/Circ.1312, or renewed; and
.5 the foam concentrates of any non-sealed portable containers and
portable tanks, and portable containers and portable tanks where production data is not documented, should be subjected to the periodical foam control tests required in MSC.1/Circ.1312.
7.12 Wheeled (mobile) fire extinguishers
.1 perform periodical inspections in accordance with the
manufacturer's instructions; .2 visually inspect all accessible components for proper condition; .3 check the hydrostatic test date of each cylinder; and
.4 for dry powder extinguishers, invert颠倒 extinguisher to ensure
powder is agitated散动的.
7.13 Galley and deep fat cooking fire-extinguishing systems
Check galley and deep fat cooking fire-extinguishing systems in
accordance with the manufacturer's instructions.
8 Two-year testing and inspections
Two-year inspections should be carried out to ensure that the indicated actions are taken for the specified equipment.
8.1 Fixed gas fire-extinguishing systems
33
.1 all high pressure extinguishing agents 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 per cent of the nominal charge. Cylinders containing less than 90 per cent of the nominal charge should be refilled; and
.2 blow dry compressed air or nitrogen through the discharge piping or
otherwise confirm the pipe work and nozzles are clear of any obstructions. This may require the removal of nozzles, if applicable.
8.2 Fixed dry chemical powder systems
.1 blow dry nitrogen through the discharge piping to confirm that the pipe
work and nozzles are clear of any obstructions; .2 operationally test local and remote controls and section valves;
.3 verify the contents of propellant推进剂 gas cylinders (including remote
operating stations);
.4 test a sample of dry chemical powder for moisture content; and
.5 subject the powder containment vessel安全壳, safety valve and
discharge hoses to a full working pressure test.
9 Five-year service
At least once every five years, the following inspections should be carried out for the specified equipment.
9.1 Fixed gas fire-extinguishing systems
Perform internal inspection of all control valves.
9.2 Foam fire-extinguishing systems
34
.1 perform internal inspection of all control valves;
.2 flush all high expansion foam system piping with fresh water,
drain and purge 净化with air;
.3 check all nozzles to prove they are clear of debris; and
.4 test all foam proportioners泡沫比例混合器 or other foam mixing
devices to confirm that the mixing ratio tolerance公差 is within +30 to -10% of the nominal mixing ratio defined by the system approval.
9.3 Water mist, water spray and sprinkler systems
.1 flush all ro-ro deck deluge system 密集洒水系统piping with water,
drain and purge with air; .2 perform internal inspection of all control/section valves; and
.3 check condition of any batteries, or renew in accordance with
manufacturer's recommendations.
9.4 Breathing apparatus
Perform hydrostatic testing of all steel self-contained breathing apparatus cylinders. Aluminium and composite cylinders should be tested to the satisfaction of the Administration.
