11、lished by BSI Standards Limited, under licence from The British Standards Institution, and came into effect on 30 November 2014. It was prepared by Panel FSH/24/-/3, Revision of PD 7974-5, under the authority of Technical Committee FSH/24, Fire safety engineering. A list of organizations represented
12、 on this committee can be obtained on request to its secretary. Supersession This Published Document supersedes PD 7974-5:2002, which is withdrawn. Relationship with other publications This Published Document takes information on building characteristics and the design fire from the qualitative desi

It provides information on the effect of fire service activities on the growth of the fire, which is used by sub-system 1 (PD 7974-1). PD 7974-5
14、 is a new part of the PD 7974 series. The series comprises: Part 0: Guide to design framework and fire safety engineering procedures; Part 1: Initiation and development of fire within the enclosure of origin (Sub-system 1); Part 2: Spread of smoke and toxic gases within and beyond the enclosure of o
15、rigin (Sub-system 2); Part 3: Structural response and fire spread beyond the enclosure of origin (Sub-system 3); Part 4: Detection of fire and activation of fire protection systems (Sub-system 4); Part 5: Fire and rescue service intervention (Sub-system 5); Part 6: Human factors Life safety strategi
16、es Occupant evacuation, behaviour and condition (Sub-system 6); Part 7: Probabilistic risk assessment; Part 8: Property protection, business and mission continuity, and resilience. These Published Documents are intended to be used in support of BS 7974. Information about this document This is a full
17、 revision of the standard and introduces the following principal changes: the standard has been rewritten to accommodate changes resulting from the National standards of fire cover having been withdrawn and replaced by locally determined standards of fire cover developed through a process called “in
18、tegrated risk management planning”; guidance is provided on the relationship between building design and fire and rescue service operating procedures. PUBLISHED DOCUMENT PD 7974-5:2014 The British Standards Institution 2014 1Use of this document As a guide, this Published Document takes the form of
19、guidance and recommendations. It should not be quoted as if it were a specification or a code of practice and claims of compliance cannot be made to it. Presentational conventions The guidance in this standard is presented in roman (i.e. upright) type. Any recommendations are expressed in sentences
20、in which the principal auxiliary verb is “should”. Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element. Contractual and legal considerations This publication does not purport to include all the necessary provisions
21、 of a contract. Users are responsible for its correct application. Compliance with a Published Document cannot confer immunity from legal obligations. PUBLISHED DOCUMENT PD 7974-5:2014 2 The British Standards Institution 2014Introduction This Published Document is one of a series of documents intend
22、ed to support BS 7974. BS 7974 provides a framework for developing a rational methodology for design using a fire safety engineering approach through the application of scientific and engineering principles to the protection of people, property and the environment from fire. The Published Documents
23、(PDs) contain guidance and information on how to undertake quantitative and detailed analysis of specific aspects of the design. They are a summary of current practice and it is intended that they be updated as new theories, calculation methods and/or data become available. They do not preclude the
24、use of appropriate methods and data from other sources. BS 7974 can be used to define one or more fire safety design issues to be addressed using fire safety engineering. The appropriate PD(s) can then be used to set specific acceptance criteria and/or to undertake detailed analysis. A fire safety e
