PUBLISHED DOCUMENT PD7974-5:2014 Foreword Publishing information This Published Document is published by BSI Standards Limited under licence from The British Standards Institution and came into effect o s / ed s uo PD 7974-5 under the authority of Technical Committee FSH/24 Fire safety engineering. A list of organizations represented on this mittee 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 Supersession This Published Document supersedes PD 7974-5:2002 which is withdrawn.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 design review (QDR) together with the time of fire service notification from sub-system 4 (PD 7974-4) and the time of evacuation from sub-system 6 (PD 7974-6). 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 is a new part of the PD 7974 series. The series prises: Part O: 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 origin (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 strategies - 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 revision of the standard and introduces the following principal changes: the standard has been rewritten to acmodate changes resulting from the National standards of fire cover having been withdrawn and replaced by locally determined standards of fire cover developed through a process called “integrated risk management planning*: guidance is provided on the relationship between building design and fire and rescue service operating procedures. @ The British Standards Institution 2014●1
