Decision structuring method for the selection of fixed firefighting systems: Development and lessons learned from case studies

Abstract

Following a major fire, an historic structure in the UK has been rebuilt to an impressive standard. The fire protection strategy developed as part of the re-build process outlines the six key elements, which all focus on 'life safety' as opposed to 'property protection' ambitions. A 'property protection' approach (more commonly adopted in cases where assets and business continuity are to be protected) usually assures of protection of both life and property, whilst a 'life safety' approach considers a structure sacrificial, once sufficient time has been allowed for safe evacuation. In this case one might expect the protection strategy to place some considerable emphasis upon the need to protect the object itself in the event of another fire. A watermist fixed firefighting system was installed. Such systems are not supported by equivalently rigorous standards, installation and product certifications when compared to the predominant alternative technology; sprinkler systems. The resultant fire risk management and resilience measures were of concern to experts. This case study presents learning opportunities which have potential to inform future risk management strategies and therefore improve decision support. The aim of this research is to better understand current practice in risk analysis and selection of fixed firefighting systems as part of the fire risk management strategy. Building upon previous work, this paper reports on case studies illustrating aspects of system selection practice and how this experience can contribute to the underpinning knowledge on which to base selection decisions. The paper concludes by considering the likely impact of the development of a Fixed Firefighting System Selection Tool (FFSST). © 2014 WIT Press.
