Fire Safety Engineering: Firefighting provisions
cibse.org/b2plive @CIBSE #Build2Perform
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’)

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

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 peoplefight fire
- Provision of internal firefighting facilities for firefighters to complete their tasks
- Ventilation of heat and smoke from a fire in a basement

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?

Key firefighting provisions (not exhaustive!)

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)
• Consideration of emerging technologies/ equipment
• Consideration of new fire strategy concepts (e.g. refuge floors for super high rise buildings)
• Environmental considerations (firefighting related)

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)
