.4 Fixed high-expansion foam fire-extinguishing systems in machinery spaces (R 9)

Directive 2009/45/EC of the European Parliament and of the Council of 6 May 2009 on safety rules and standards for passenger ships (Recast) (Text with EEA relevance ) · European Union

Any required fixed high-expansion foam system in machinery spaces shall be capable of rapidly discharging through fixed discharge outlets a quantity of foam sufficient to fill the greatest space to be protected at a rate of at least 1 metre in depth per minute. The quantity of foam-forming liquid available shall be sufficient to produce a volume of foam equal to five times the volume of the largest space to be protected. The expansion ratio of the foam shall not exceed 1000 to 1. Supply ducts for delivering foam, air intakes to the foam generator and the number of foam-producing units shall be such as will provide effective foam production and distribution. The arrangement of the foam generator delivery ducting shall be such that a fire in the protected space will not affect the foam generating equipment. The foam generator, its sources of power supply, foam-forming liquid and means of controlling the system shall be readily accessible and simple to operate and shall be grouped in as few locations as possible at positions not likely to be cut off by a fire in the protected space. Fixed high-expansion foam fire-extinguishing systems in machinery spaces shall comply with the provisions of the Fire Safety Systems Code.
