GUIDELINES FOR THE PERFORMANCE AND TESTING CRITERIA
AND SURVEYS OF LOW-EXPANSION FOAM CONCENTRATES
FOR FIXED FIRE-EXTINGUISHING SYSTEMS
1 The Maritime Safety Committee, at its seventy-second session (17 to 26 May 2000), approved, as proposed by the Sub-Committee on Fire Protection at its forty-fourth session, a corrigendum to MSC/Circ.582 on Guidelines for the performance and testing criteria and surveys of low-expansion foam concentrates for fixed fire-extinguishing systems, as set out in the annex.
2 Member Governments are invited to take account of the annexed modifications to the aforementioned circular and bring them to the attention of all parties concerned.
ANNEX
MODIFICATIONS TO THE GUIDELINES FOR THE PERFORMANCE AND TESTING CRITERIA AND SURVEYS OF LOW-EXPANSION FOAM CONCENTRATES FOR FIXED FIRE-EXTINGUISHING SYSTEMS (MSC/CIRC.582)
Corrigenda
1 In the title of MSC/Circ.582 replace the word "FROM" with "FOAM".
2 The following modifications are made to the text of the annex to MSC/Circ.582:
.1 the existing text in paragraph 3.7.1 is replaced by the following new text:
"3.7.1 The test should be carried out according to paragraph 3.7.2 with simulated seawater at about 20℃ having the characteristics stated in paragraph 3.7.3.";
.2 in paragraph 3.7.2 (b.1), in the fourth sentence, the flow rate of "6 L/min" is replaced by "11.4 L/min";
.3 the existing text in paragraph 3.8.2 is replaced by the following new text:
"3.8.2 The test should be carried out with simulated seawater at about 20℃ having the characteristics stated in paragraph 3.7.3.";
.4 the existing text in paragraph 3.9.3 (b) is replaced by the following new text:
"(b) The test should be carried out with simulated seawater at about 20℃ having the characteristics stated in paragraph 3.7.3."; and
.5 in paragraph 3.9.6 (a), the second sentence is replaced by the following:
"(a) Add approximately 90 L of simulated seawater having the characteristics stated in paragraph 3.7.3 and check that the base of the tray is completely covered."

GUIDELINES FOR THE MAINTENANCE AND INSPECTION OF
FlRE-PROTECTION SYSTEMS AND APPLIANCES
1 The Maritime Safety Committee, at its sixty-ninth session (11 to 20 May 1998), recognizing the importance of proper maintenance and inspection of fire-protection systems and appliances, approved Guidelines for the maintenance and inspection of fire-protection systems and appliances, as set out in the annex.
2 Member Governments are invited to bring the annexed Guidelines to the attention of shipowners, shipmasters, ships' officers and crew and all other parties concerned.
ANNEX
GUIDELINES FOR THE MAINTENANCE AND INSPECTION OF
FIRE-PROTECTION SYSTEMS AND APPLIANCES
1 Application
These Guidelines apply to all ships, however it does not contain an exhaustive list of maintenance items and should be used as a recommendation only.
2 Operational readiness
All fire protection systems and appliances should at all times be in good order and available for immediate use while the ship is in service. If a fire protection system is under repair, then suitable arrangements should be made to ensure safety is not diminished.
3 Maintenance and testing
Instructions for on-board maintenance, not necessarily by the ship's crew, and testing of active and passive fire protection systems and appliances should be easily understood, illustrated wherever possible, and, as appropriate, should include the following for each system or appliance:
.1 maintenance and repair instructions;
.2 schedule of periodic maintenance;
.3 list of replaceable parts; and
.4 log for records of inspections and maintenance, listing identified non-conformities and their targeted completion dates.
4 Weekly testing and inspections
Weekly inspections should be carried out to ensure that:
.1 all public address systems and general alarm systems are functioning properly; and
.2 breathing apparatus cylinders do not present leakages.
5 Monthly testing and inspections
Monthly inspections should be carried out to ensure that:
.1 all fireman's outfits, fire extinguishers, fire hydrants, hose and nozzles are in place, properly arranged, and are in proper condition;
.2 all fixed fire-fighting system stop valves are in the proper open or closed position, dry pipe sprinkler systems have appropriate pressures as indicated by gauges;
.3 sprinkler system pressure tanks have correct levels of water as indicated by glass gauges;
.4 all sprinkler system pumps automatically operate on reduction of pressure in the systems;
.5 all fire pumps are operated; and
.6 all fixed fire-extinguishing installation using extinguishing gas are free from leakage.
6 Quarterly testing and inspections
Quarterly inspections should be carried out to ensure that:
.1 all automatic alarms for the sprinkler systems are tested using the test valves for each section;
.2 the international shore connection is in proper condition;
.3 lockers providing storage for fire-fighting equipment contain proper inventory and equipment is in proper condition;
.4 all fire doors and fire dampers are tested for local operation; and
.5 all CO2 bottle connections for cable operating system clips should be checked for tightness on fixed fire-extinguishing installations.
7 Annual testing and inspections
Annual inspections should be carried out to ensure that:
.1 all fire extinguishers are checked for proper location, charging pressure, and condition;
.2 fire detection systems are tested for proper operation, as appropriate;
.3 all fire doors and dampers are tested for remote operation;
.4 all foam-water and water-spray fixed fire-fighting systems are tested for operation;
.5 all accessible components of fixed fire-fighting systems are visually inspected for proper condition;
.6 all fire pumps, including sprinkler system pumps, are flow tested for proper pressures and flows;
.7 all hydrants are tested for operation;
.8 all antifreeze systems are tested for proper solutions;
.9 sprinkler system connections from the ship's fire main are tested for operation;
.10 all fire hoses are hydrostatically tested;
.11 breathing apparatus air recharging systems checked for air quality;
.12 control valves of fixed fire-fighting systems should be inspected; and
.13 air should be blown through the piping of extinguishing gas systems.
8 Five-year service
At least once every five years, the following inspections and tests should be carried out:
.1 hydrostatic testing for all SCBA's cylinders; and
.2 control valves of fixed fire-fighting systems should be internally inspected.
