Publishing information
This part of BS 5306-0 is published by BSI Standards Limited under licence from The BritishStandards Institution and came into effect on 31 August 2020. It was prepared by Technical Committee FSH/18 Fixed fire fighting systems. A list of organizations represented on this mitteescan be obtained on request to the mittee manager.
Supersession
This part of BS 5306 supersedes BS 5306-0:2011 which is withdrawn.
Relationship with other publications
This part of BS 5306 serves to introduce the subsequent parts of BS 5306 and references otherstandards as listed below and detailed in the Bibliography each of which gives requirements or remendations for the application of a particular type of firefighting system discharging aparticular firefighting medium. Taken together the various parts of BS 5306 and other BritishStandards are intended to cover all the main types of firefighting media and systems for buildings incurrent use and therefore form a prehensive guide to all aspects of the subject.
The subsequent parts of BS 5306 are as follows:
*Part 1: Hose reels and foum inlets;●Part 3: Commissioning and maintenance of portable fire extinguishers Code of practice;*Part 4: Specification for carbon dioxide systems;Part 5: Halon systems:Section 5.1: Specification for Haion I301 total flooding systems;Section 5.2: Halon 1211 total flooding systems;●Part 8: Selection and installation of portable fire extinguishers Code of practice;▪ Part 9: Recharging of portable fire extinguishers Code of practice;Part 10: Colour coding to indicate the extinguishing medium contained in portable fireextinguishers - Code of practice.
The following parts of BS 5306 have been superseded:
Part 2: Specification for sprinkler systems (superseded by BS EN 12845 Fixed firefighting systems Aartomatic sprinkler systems Design instollation and maintenance):Part 6: Foom systems (superseded by BS EN 13565-2 Fixed firefighting systems Foom systems Part 2: Design construction and maintenance): .S Section 6.1: Specification for low expansion foam systems;*Section 6.2: Specification for medium and high expansion foam systems;•Part 7: Specification for powder systems (superseded by BS EN 12416-2 Fixed firefighting systems Powder systems Part 2: Design construction and maintenance).
Other related standards are detailed in Clause 14.
