BS 5588-9:1999 Foreword This part of BS 5588 was prepared by Technical Committee FSH/25. It supersedes BS 5588-9:1989 which is withdrawn. The start and finish of text introduced or altered by amendment is indicated in the text by tags E . Tags indicating changes to text carry the number of the amendment. For example text altered by Amendment No. 1 is indicated by . All matters dealing with fire safety management are now located in BS 5588-12. Other parts which prise BS 5588 are as follows: Part O: Guide to fire safety codes of practice for particular premisesfapplications; --Part 1: Code of practice for residential buildings; -Part 4: Code of practice for smoke control using pressure differentials -Part 5: Code of practice for firefighting stairs and lifts; Part 6: Code of practice for places of assembly; -Part 7: Code of practice for the incorporation of atria in buildings; -Part 8: Code of practice for means of escape for disabled people; --Part 10: Code of practice for shopping plexes; similar buildings; Part 11: Code of practice for shops offices industrial storage and other Part I2: Managing fire safety. Some of the more important changes introduced in this revision of this part of BS 5588 are as follows. a) Intumescent dampers are now included. b) Alternative solutions are given to smoke detector control of fire/smoke dampers in hotels. c) Provision of smoke detector operated fire/smoke dampers in places of entertainment hospitals and premises with a sleeping risk is now included. d) Changes have been made to the three methods of protecting ductwork. e) Remendations are given for ductwork passing through escape routes. f) Remendations have been added for the following: 1) fire dampers; 2) the installation of ductwork systems; 3) fan rooms; 4) transfer grilles; 5) air handling voids; 6) recireulating distribution systems; 7) firefighting controls; and 8) domestic heating ventilation and air conditioning (HVAC) systems. It has been assumed in the drafting of this standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people. As a code of practice this British Standard takes the form of guidance and remendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of pliance are not misleading. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. In particular attention is drawn to 4.4.

BS 5588-9:1999 Introduction The fire proteetion of ventilation systems has in the past tended tobe considered primarily in the context of the breakdown of fire partmentation in buildings. Ventilation systems and ductwork however can be responsible for accelerating the initial spread of fire for example between rooms within a fire partment and perhaps of even more importance by the rapid of any given type of building or occupancy. This standard draws attention to the potential fire dangers associated with ventilation and air conditioning protective measures the adoption of which should effectively counterbalance the potential dangers of fire. It offers guidance on the appropriateness of such protective methods in a range of cireumstances. However occupancy. Each project needs to be examined by the designer to identify the potential dangers before selecting the appropriate protective measures. A fire can generate large quantities of bustion products (usually referred to as “smoke") namely hot gases carrying smoke particles and containing toxic or noxious and irritant products. The standard is mainly concerned with providing advice on the selection of appropriate measures for the effective isolation of the ventilation system that will confine fire smoke and deposition products within a pre-selected area of the building or within the system itself in such a way that other areas are subject neither to fire attack nor to the spread of smoke and/or toxic gases. In the event of a fire within a building ventilation by natural or mechanical means can be used to limit the spread of these products which could otherwise hinder or prevent escape and thus endanger the lives of the for ventilation in the event of fire may on occasion be inpatible with those for normal ventilation. In most cases larger flows of air or gases have to be allowed for in directions sometimes different from those required for normal ventilation. Experimental evidence of the efficacy of measures to prevent fire spread by way of duetwork is scarce. A considerable international effort is being made aimed at a better understanding of the problems of fire and smoke spread associated with ventilation ductwork. In particular this concerns the pressure distribution throughout a building and how this is affected either directly or indirectly by fire. This standard is based on the best available information in respect of both practical experience and scientific investigation. Throughout the standard life safety is the primary consideration underlying the remendations. However the standard also covers matters which are relevant to the protection of the building and its contents from fire as well as to the safety of the oceupants. 1Scope This part of BS 5588 provides guidance for designers and the building construetion team on the incorporation of ventilation and air conditioning ductwork into new and existing buildings other than premises covered by BS 5908. NOTE 1It is esential that the recmmendatiosgivenn this part ofB5588areappliedanew f physicalalteratiomsaremade t an existing building which have a detrimental effect on the means of escape from the building even if such alterations are not structural. The standard covers non-bustible building service ducts and ductwork manufactured from metal and/or rigid mineral based ponents which exhibit: a) high integrity when exposed to fully developed fire conditions; b) resistance to penetration by flame; c) an ability to exclude or contain fire. It does not cover ductwork manufactured from materials that rapidly melt shatter or degrade during fire exposure for example glass and plastics materials.
