MSC.1/Circ.1432
31 May 2012
REVISED GUIDELINES FOR THE MAINTENANCE AND INSPECTION OF FIRE
PROTECTION SYSTEMS AND APPLIANCES
1 The Maritime
Safety Committee, at its ninetieth session (16 to 25 May 2012), having
considered a proposal by the Sub-Committee on Fire Protection, at its
fifty-fifth session, and recognizing the need to include maintenance and
inspection guidelines for the latest advancements in fire-protection systems
and appliances, approved the Revised Guidelines for the maintenance and inspection
of fire protection systems and appliances, as set out in the annex.
2 Member Governments
are invited to apply the annexed Guidelines when performing maintenance,
testing and inspections in accordance with SOLAS regulation II-2/14.2.2.1 on or
after 31 May 2013 and bring the annexed Guidelines to the attention of
shipowners, shipmasters, ships' officers and crew and all other parties
concerned.
3 This circular
supersedes MSC/Circ.850.
ANNEX
REVISED GUIDELINES FOR THE MAINTENANCE AND INSPECTION OF FIRE
PROTECTION SYSTEMS AND APPLIANCES
1 Application
These Guidelines apply to all ships and provide the minimum
recommended level of maintenance and inspections for fire protection systems
and appliances. This information may be used as a basis for the ship's onboard
maintenance plan required by SOLAS regulation II-2/14. These Guidelines do not
address maintenance and inspection of fixed carbon dioxide systems or portable
fire extinguishers. Refer to the comprehensive instructions provided in the
Guidelines for the maintenance and inspections of fixed carbon dioxide
fire-extinguishing systems (MSC.1/Circ.1318) for fixed carbon dioxide
systems, and in the Improved Guidelines for marine portable fire extinguishers
(resolution A.951(23))
for portable fire extinguishers.
2 Operational
readiness
All fire protection systems and appliances should at all times be
in good order and readily available for immediate use while the ship is in
service. If a fire protection system is undergoing maintenance, testing or
repair, then suitable arrangements should be made to ensure safety is not
diminished through the provision of alternate fixed or portable fire protection
equipment or other measures. The onboard maintenance plan should include
provisions for this purpose.
3 Maintenance and
testing
3.1 Onboard maintenance
and inspections should be carried out in accordance with the ship's maintenance
plan, which should include the minimum elements listed in sections 4 to 10 of
these Guidelines.
3.2 Certain maintenance
procedures and inspections may be performed by competent crew members who have
completed an advanced fire-fighting training course, 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 are to be completed by trained personnel.
3.3 Inspections should
be carried out by the crew to ensure that the indicated weekly, monthly,
quarterly, annual, two-year, five-year and ten-year actions are taken for the
specified equipment, if provided. Records of the inspections should be carried
on board the ship, or may be computer-based. In cases where the inspections and
maintenance are carried out by trained service technicians other than the
ship's crew, inspection reports should be provided at the completion of the
testing.
3.4 In addition to the
onboard maintenance and inspections stated in these Guidelines, manufacturer's
maintenance and inspection guidelines should be followed.
3.5 Where particular
arrangements create practical difficulties, alternative testing and maintenance
procedures should be to the satisfaction of the Administration.
