These Revised guidelines provide the minimum recommended level of
maintenance and inspections for fixed carbon dioxide fire-extinguishing 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 Revised guidelines are intended to supplement
the fire-extinguishing system manufacturer's approved maintenance instructions. Certain
maintenance procedures 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 personnel.
