It is a massive effort to rewrite a national fire safety code around measurable risk, explicit targets, and cost-effectiveness. But sometimes, there are great reasons to do so. In this episode, together with Gianluca De Sanctis and Sofia Kourgiantaki we take you inside Switzerland’s sweeping reform, where a new federal law sets a maximum individual risk for life safety, ties property protection to a clear marginal cost rule, and harmonises practice across cantons. Together, we trace how the f...
Demand for the energy storage is as high as ever, and is about to triple-quadruple. The development of technology is at unprecedented phase, and even within a single project you may face different cell, battery or container generations. This pace reshapes how we think about battery energy storage safety, from enclosure design to emergency response. We sat down with Noah Ryder from the Fire and Risk Alliance to unpack how BESS has evolved from walk-in containers to dense, modular “refrigerator...
This week, in the Fire Science Show, we host a roundtable discussion on complexities in fire safety science and engineering. Most safety failures don’t come from a single mistake—they emerge when people, technology, and institutions misalign. In an ever-changing field in which complexities just go up, we open up a debate on how to cope with that so that the entire field goes in the right direction. For this podcast roundtable debate, I've invited Steve McGuirk, who represents Fire Sector Conf...
In this episode of the Fire Science Show we invite dr. Antonela Čolić from the OFR Consultants, to break down the performance of adhesives used in CLT in fire, what differences between the glues are observable at the microscale and how they show up in real structure fires. We compare common polyurethane adhesives: one that softens near 200–220 C and one that resists softening, crosslinks, and ultimately chars. Through thermogravimetric and calorimetric testing, we map pivotal transition...
In this episode we try to demonstrate another step in integrating fire engineering into WUI risk management, and vice versa. These two areas together form some sort of fire engineering method, which I strongly believe will be an important part of our profession in the future. Today I got to sit down with Dr. Pascale Vacca from UPC to unpack a practical, end-to-end framework for wildland–urban interface risk that engineers can use today, which she has shared in her keynote at the ESFSS Confere...
Fire doesn’t play by Earth’s rules once you leave gravity behind. In this deep dive with Professor Michael Gollner, we unpack what the recent experiments at the ISS called SoFIE-MIST taught us about solid fuel flammability in microgravity—how tiny ventilation, oxygen levels, and pressure shifts determine whether a flame spreads, stalls, or vanishes. The details are surprising: blue “bubble” flames, two distinct extinction points, and sustained burning at oxygen levels that would fail to ignit...
In this episode we dive into the ap between standardized tests and experiments, trying to figure out (a) is there a difference and (b) if there is, could not understanding the difference quietly erode safety. With guest David Morrisset (Queensland University), we unpack furnace ratings that read like time but aren’t, cladding classifications that were never meant for façades, and the infamous bird-strike test that shows how any standard bakes in choices and consequences. The throughline: cont...
In this episode, we give focus to the SFPE Foundation – a catalyst transforming how fire engineering research is funded, conducted, and shared globally. In this conversation with Leslie Marshall, Interim Executive Director of the SFPE Foundation, we discover how a relatively small organization has distributed over $1.2 million in grants, scholarships, and research funding since 2021. While the Foundation has existed since 1979, its recent expansion with dedicated staff has accelerated its imp...
What happens when the flames die down? It's a question rarely addressed in fire engineering, yet the decay and cooling phases of fires can be more dangerous than peak fire conditions. In this deep-dive conversation with Dr. Andrea Lucherini from Frisbee at ZAG in Slovenia, we uncover why these overlooked phases matter profoundly for structural safety. Most engineers focus on protecting structures during the fully developed fire phase, but as Dr. Lucherini reveals, catastrophic failures can a...
In my personal view, an alarming truth about building fire safety lies in the gap between what's designed and what actually works in a building. After conducting 1000+ hot smoke tests in 200+ buildings, my experience is that most (maybe even 90%) of buildings had deficiencies in their smoke control systems, with 30% experiencing issues significant enough to potentially endanger occupants during a real fire. But it's not just about the problems. Good news - we have solutions. Hot smoke testin...
What happens when we stick a thermocouple into a fire? The answer is surprisingly complex and has profound implications for fire safety engineering. In this deep-dive episode, Dr. David Morrisset from Queensland University joins Wojciech to unravel the science of fire measurements that underpins every experiment, test report, and dataset in our field. The conversation reveals a critical truth often overlooked by practitioners: measurements don't capture reality directly - they capture the in...
The devastating 2018 Camp Fire in Paradise, California serves as a haunting reminder of how rapidly wildfires can overwhelm communities. We have not known anything like it - the flames raced through Paradise at four miles per hour, 30,000 residents had mere minutes to evacuate, and many couldn't escape in time. What happens when the fire goes worse than worst case scenario, but still people need to escape? How do we protect lives when escape routes are blocked by fire or gridlocked traffic? ...
The world looks entirely different through a thermal camera lens, especially in a fire scenario. These devices reveal harsh temperature gradients between hot and cold surfaces, adding another dimension to how fire safety professionals understand and navigate dangerous environments. Thermal cameras have transformed firefighting operations with astonishing effectiveness. Studies show that in smoke-filled buildings, thermal cameras have significantly improved the changes to identify victims. Th...
The AI revolution has arrived, but fire safety engineers face a critical dilemma: how to leverage powerful AI tools while protecting confidential project data. Professor Ruggiero Rino Lovreglio from Massey University and Dr. Amir Rafe from Utah State University join us to explore the world of local Large Language Models (LLMs) - AI systems you can run privately on your own computer without sending sensitive information to the cloud. While cloud-based AI like ChatGPT raises serious priva...
When experts from different disciplines attempt to collaborate on complex problems, such as evacuation modelling, we often discover that we're not speaking the same language. Even seemingly simple terms like "density," "velocity," and "distance" carry dramatically different meanings across physics, psychology, engineering, and computer science. In this episode, we present the "Glossary for Research on Human Crowd Dynamics," a remarkable community effort that brought together over 60 research...
In episode 17 of the Fire Fundamentals, we delve into the fire detection technology. Fire detection forms the critical foundation of all active fire protection measures, serving as the prerequisite for any fire safety engineering solution to work effectively. Following key points are discussed: Detection systems must balance sensitivity with reliability to avoid false alarms that disrupt building operationsFalse alarms lead to serious business continuity issues and may eventually cause system...
In the 16th part of the Fire Fundamentals series, we invite Randy McDermott from NIST to join us for a deep dive into turbulence and its critical role in fire dynamics modelling. We explore the physics behind turbulent combustion and how it fundamentally shapes fire behaviour, plume dynamics, and simulation accuracy. In this episode we cover: Defining turbulence as the enhancement of mixing and heat transfer through the creation of eddies and instabilitiesUnderstanding length scales in turb...
In this podcast episode, I invited Chris Jelenewicz, the CEO of SFPE, to bring me up to date on the society. The SFPE Handbook on Fire Protection Engineering is undergoing a major revision with the sixth edition expected by summer's end, expanding to five volumes with significant new content on emerging topics like wildland fires and lithium-ion batteries. In this episode, we cover how the handbook is written, edited and when it will be released to the public. Some highlights from the episo...
Water might seem like the simplest part of firefighting – just point and spray, right? Well, as you can imagine, the reality is a bit more complex. In this conversation with veteran firefighter and CFBT instructor Szymon Kokot, we pull back the curtain on firefighting's most critical resource to reveal the intricate science and logistics behind effective fire suppression. Did you know a standard fire truck carries just 10 minutes' worth of water for a typical residential fire? Or that a wate...
As a consequence of the Grenfell Tower disaster, some strong legislation was proposed, such as a combustible ban on building walls. This, however, affected more than just the building facades, as it excluded materials such as laminated glass used as balcony balustrades. Today, the path forward demands evidence that could inform decisions on the future of laminated glass in this use. In this conversation with Mike Spearpoint and Konstantinos Chotzoglou from OFR Consultants, we dive deep ...
