Fire Science Show ·

2025/12/17

Today we cover another branch of safety of Battery Energy Storage Systems (BESS), that is explosion prevention in mitigation. I always thought you can either end with a fire or with an explosion, and boy I was wrong... but we will go back to this later. Now I bring on Dr. Lorenz Boeck (REMBE) and Nick Bartlett (Atar Fire) to unpack how gas released during thermal runaway turns a container into a deflagration hazard, and what it takes to design systems that actually manage the pressure, flame,...

A facility with 105 synchronized fans pushing hurricane-class wind across a full-size house while a live fire... This is not science fiction - this is a real research capacity that helps us re-shape our knowledge on the full scale building ignition, fire spread, and failure. That’s the stage at IBHS, where we dig into how wind-driven fire behave differently to small-scale and how tiny choices around a building can decide its fate. Together with my guest - dr Faraz Hedayati, we go from embers ...

229 - Learning from 900 fires with Björn Maiworm

Fire Science Show ·

2025/12/03

What can you learn after processing observations across 900 severe fires? A lot. Actually, I will send you to the paper straight away: Evaluating 900 Potentially Harming Fires in Germany: Is the Prescriptive Building Code Effective? German Fire Departments Assessed Fire Safety Measures in Buildings Through On-Site Inspections And now let's dissect this. We sit down with Björn Maiworm of the Munich Fire Department to unpack a decade of structured observations from more than 2,000 signifi...

Fire Science Show ·

2025/11/26

What do you expect from running a fire test? I would hope that it improves my state of knowledge. But do they do this? We often pursue them blindly, but it seems there is a way to do this in an informed way. In this episode we explore a rigorous, practical way to select and design experiments by asking a sharper question: which test delivers the most decision-changing information for the least cost, time, and impact. With Dr. Andrea Franchini of Ghent University, we unpack a Bayesian fr...

Fire Science Show ·

2025/11/19

A viral clip of an EV igniting was what started my worries about safety in car parks I have been designing. Are we ready for fast growing fires? Since 2019 I've learned and studied a lot, I've relaxed on some aspects of it and was able to identify they areas where a lot more engineering considerations should be placed. In this episode I would like to take you inside the engineering choices that shape outcomes: ceiling height, smoke control, structural details, and how fast systems wake up whe...

Fire Science Show ·

2025/11/12

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...

225 - Battery Energy Storage Systems with Noah Ryder

Fire Science Show ·

2025/11/05

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...

Fire Science Show ·

2025/10/29

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...

Fire Science Show ·

2025/10/15

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 Science Show ·

2025/10/08

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...

2025/09/17

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...

Fire Science Show ·

2025/09/10

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...

2025/08/20

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? ...
