BS 5588-4:1998 Foreword This code of practice was prepared under the direction of Technical Committee FSH/14. It supersedes BS 5588-4:1978 which is withdrawn.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 The other parts which prise BS 5588 are as follows: Part O: Guide to fire safety codes of practice for particular premiseslapplications; Part I: Code of practice for residential buildings; -Part 5: Code of praetice for firefighting stairs and lifts; --Part 6: Code of praetice for places of assembly; -Part 7: Code of praetice for the incorporation of atria in buildings Part 8: Code of practice for means of escape for disabled people; -Part 9: Code of practice for ventilation and air conditioning ductoork; Part 10: Code of practice for shopping plexes; Part 11: Code of practice for shops offices industrial storage and other similar buildings; Part 12: Managing fire safety. It has been assumed in the drafting of this code 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.
