Matthew Ryan The Fire Su Surgery Ltd Fire Safety Engineering: Firefighting provisions
Overview Fire strategies and the importance of firefighting provisions • The fire service as a stakeholder • Key firefighting provisions • CIBSE Guide E approaches (Chapter 13) • Operational building management • (Will try to keep in the context of building services, and not too ‘London-centric’) cibse.org/b2plive @CIBSE #Build2Perform
Fire strategies and importance of firefighting provisions Definition; BS7974: 2019 • Formal fire strategy document; historically • performance based design, now expected for most buildings (apart from the simplest) PAS911: 2007 – how to write • B1 to B5 (including Regulation 7) of the • Building Regulations 2010 B5 Access and facilities for the fire service • cibse.org/b2plive @CIBSE #Build2Perform
Fire strategies and importance of firefighting provisions Functional requirement B5 • Primarily life safety related; increasing property • protection and business continuity objectives for some sectors. Four key areas: • - External fire service vehicle access - Access into and within the building to: search for and rescue people fight fire - Provision of internal firefighting facilities for firefighters to complete their tasks - Ventilation of heat and smoke from a fire in a basement Excerpts from Approved Document B Volume 2 (2019); https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/832633/Approve d_Document_B__fire_safety__volume_2_-_2019_edition.pdf cibse.org/b2plive @CIBSE #Build2Perform
The fire service as a stakeholder Fire safety design process (the fire strategy) • Design objectives, specific to each project • Various stakeholders; fire service should always be considered • as one of these. M&E also a key stakeholder Fire service needs/ views/ opinions? Geographical differences? • Not just an ‘approver’; they interact with the building and its • systems when there is a fire Need for early consultation with the local fire and rescue • service? cibse.org/b2plive @CIBSE #Build2Perform
Key firefighting provisions (not exhaustive!) cibse.org/b2plive @CIBSE #Build2Perform
CIBSE Guide E approaches Collation of ‘code compliant’ benchmark design guidance • references for key firefighting provisions and related building services items References to relevant related ‘progressive’ guidance (e.g. • BS8899: 2016 for lifts for use in the event of fire) Bronto Skylift F295HLA Consideration of emerging technologies/ equipment • Consideration of new fire strategy concepts (e.g. refuge • floors for super high rise buildings) Environmental considerations (firefighting related) • Burj Khalifa, Dubai cibse.org/b2plive @CIBSE #Build2Perform
CIBSE Guide E approaches – fire engineering Acknowledgement of firefighter PPE limitations (for design • purposes) Potential enhancements to fire service access (intelligent • fire detection/ alarm/ notification, twin landing valves for fire mains, etc) Appreciation of typical fire service operational procedures • Typical firefighting shaft design variations • Firefighting timelines • Building services play a central role to all • cibse.org/b2plive @CIBSE #Build2Perform
CIBSE Guide E approaches – an example Engagement with local fire and • rescue service Fire service vehicle access • Firefighting water supplies • Dry horizontal fire main • Automatic suppression • systems Fire detection and alarms • cibse.org/b2plive @CIBSE #Build2Perform
Operational building management All fire safety systems: knowing what you have, how it works, and when/ how to • test and maintain it Firefighting facilities sometimes overlooked • Complex buildings/ systems – ‘in house’ expertise • CIBSE Guide E Chapter 14 – management and maintenance • Importance of fire strategy, Regulation 38 information, etc • Specialist building services support where appropriate • Planning for a fire incident • Contingency planning for systems (spares, etc) • cibse.org/b2plive @CIBSE #Build2Perform
