I was first introduced to the work of Paul Bryant through his book, Fire Strategies-Strategic Thinking. It was in this book that he first introduced the idea of holistic fire strategies. Through our interactions I was afforded the privilege to contribute to his most recent book, Holistic Fire Strategies: The Search for a Global Methodology.
“This book explores the concept of holistic fire strategies - an idea developed by the author to provide a more inclusive and global approach to fire safety engineering and the preparation of fire strategies…It is suggested that fire strategies can be formulated and evaluated in a globally consistent manner. He suggests that the whole process can be controlled online which will improve consistency, reduce wasted resources and provide a much needed audit trail. The book includes some "soft" calculus to offer an alternative method to analyze fire risk as well as a novel method to assess actual fire strategies against a baseline version.”
The fire industry has seen a broad shift from prescriptive based to performance-based codes. However, there are still issues to be addressed. These issues require a new evolution in fire engineering methodology.
A performance based approach can potentially allow for a spectrum of solutions. However, what determines that the solution put forward is the most optimal in terms of efficiency, logistics and economics?
There remains confusion and mistrust regarding a performance-based approach. Those with the responsibility for approvals ask if the design solution is “code compliant” which is probably not the correct terminology given the flexibility in application.
A number of national regulations still do not adequately embrace performance-based solutions.
“This fire strategy does not consider extreme events”. What may have been once an extreme event may now be more commonplace. Should not a strategy consider everything that could realistically lead to a fire?
There is still insufficient buy-in from stakeholders. Project meetings can end up as a tussle between the fire engineer, architect, client, project managers, or enforcers.
Holistic fire engineering embraces the following principles:
1. To ensure that a fire engineered solution properly accounts for the real and perceived threats affecting the building, its occupancy and processes. Extreme events may or may not be included based upon a risk evaluation.
2. That we consider, fully, all objectives, and not just those applicable to national regulations. Note that comparison with national regulations will need to be included within the process.
3. We use all recognized means to develop holistic fire strategies.
4. Critical to holistic fire engineering is that the analysis and design process is controlled by a measurement system to allow full auditability and comparison at any stage of the process. Consequently, third parties can be provided with greater assurance that the solution is compliant with “holistic fire engineering” metrics.
5. The process and metrics must be transferable globally such that they will be the same wherever they are applied.
Recently Paul and I met to discuss developing a cross continental online platform to allow the formulation and verification of fire strategies for all complex building profiles, wherever they are. As the development continues, we will keep those interested up to date. For those who would like to be more involved, please go to www.igni.online and register your interest.
