Fire Science, Engineering And Education Episodes

The relation between ventilation conditions and fire severity is quite a fundamental one. You don't even have to be a fire safety engineer to realize that more air means a bigger fire. But how does air get into the compartment fire in the first place? Through broken windows of course! And here we come to the subject of today's episode. Because with all the considerable improvements in glazing technologies for building facades, is it really okay to assume that the glazing has failed and all we ar...

Have you wondered how fire science started? But I mean the real real start... not 1666 one, nor the one when we've started to build furnaces... The start when the first evolutionary ancestor of homo sapiens figured out this warm bright thing could be used to process food. The start when this bright thing was protected and used intentionally. The bright thing that was so important for our kind, that the proof for this relationship can be found literally in our anatomy... The best way to study thi...

The subject of structural fire engineering was long overdue in the podcast schedule. But once I finally got it on my agenda, I made sure to interview one of the very best there are - prof Thomas Gernay of John Hopkins University. Not only a structural engineer and researcher, but also one of the developers of SAFIR® - one of most popular structural fire engineering numerical codes out there. In this discussion I get to ask some important questions on the role structural fire engineering plays i...

How does being a volunteer firefighter improve your abilities to do Performance-Based Design (PBD) and how your knowledge in PBD may translate to firefighting? That is not a question you can ask to every fire protection engineer, but luckily - David Stacy is one who can answer that fully. Tapping into his unique skillset and career path I try to extract answers on how does one translate firefighting experience into improved design. Where does he see the most immediate gain (duh - communication!)...

It has been one year since I started this show. I've promised you that we will learn Fire Safety Engineering together, and today comes a great time to reflect on some lessons learnt. In this episode, I will take you on a short journey through some most insightful moments in the show, that allowed me to identify the number one skill needed to thrive as a fire protection engineer. What is that skill? Well press the play button and find it for yourself! The answer is 35 minutes away, and I promise ...

In this show, we often discuss how fire science can help firefighters. Today we drop the UNO reverse card and figure out what firefighters actually need from fire science. And for that, I've got a perfect person to talk to - a firefighter, commander, instructor and a fire scientist. Szymon Kokot of the Nidzica Fire Brigade and CFBT Poland With this talk, I wanted to achieve two answers. How firefighters view fire science (and how to make it more useful to them). And how engineers should view fir...

This week we do something funny - a crossover episode with the host of the Fire Code Tech podcast - Gus Gagliardi. We end up discussing the paths of fire safety engineers, from school to specialized roles in engineering companies, and the challenges associated with that. We hope you liked this twist to the podcast, and maybe discovered a new show to follow up! If you want to hear a familiar voice, you can start with this episode https://firecodetech.com/research-smoke-control-systems-and-cfd-wit...

How does one decide when a building is fire safe? That is a real hell of a question to answer! Is it when no harm can occur? But such a condition can never be fulfilled... there is always a meteor waiting around the corner to fall into your building! So if some situations can occur for which we cannot prepare, when do we decide we are 'safe enough'? This is the tough question we try to decipher together with prof. Ruben van Coile and prof. Danny Hopkin. It is an inspiring journey, and you can tr...

It is always a pleasure to interview a true legend of fire safety. And when the topic of the interview is their thoughts on neglected areas of our discipline, based on almost five decades of experience? This must end up great! And it did (IMHO). Please join me and prof. Vyto Babrauskas in discovering what are the parts of fire science that are in need of research. What are some obvious solutions, that I think we all acknowledge, but for some reason, we do not have? What are the dead ends and mis...

We all understand the dangers of smoke inhalation in fires. But what about the site of the fire a few days after it was put out? It looks clean, maybe even lost the smell... Is it something to worry about, or you can rush straight in, wearing your shorts and a t-shirt? Well, I guess I would not be that reckless, but if I can be honest - I don't think I would care that much about protecting myself either... At least that was me before the talk to dr Gavin Horn from UL FSRI. Gavin spent more than ...

How reliable are sprinkler systems? Is it 100%? Is it 95%? Maybe it is 88%... actually, whatever the number is, do we truly understand what does it represent? What does it mean that a sprinkler has succeeded and what does it mean it failed. These are the questions that were behind my today's interview with Arnstein Fedoy. You may remember Arnstein from his short appearance in episode 26 . This time, we've had the whole episode for this discussion, and I must say it was well invested hour on my ...

Can water mist be used in tunnels? I wondered that for a long time, and with every tunnel project, many questions around this issue were piling in my head. When dealing with large infrastructure projects you really need to work your way around multiple functional aspects of a system - maintenance, water and power consumption, drainage capacity, availability of elements and their certification... You would love to focus purely on the fire safety aspect of the issue, but you cannot. Unfortunately...

This is not a fun episode. It starts with a tragedy, that fueled a whole field of research. Continues into disbelief, that one aspect of fire safety can be at the same chosen as the sole foundation of fire safety within a branch of engineering, and at the same time at a pretty low, clearly insufficient level... And then comes the true shocker - solutions exist and we just don't use them. Because of, who knows why. An unknown force... Ok, I have spoiled you a bit, but it is absolutely worth heari...

In Episode 18 we have touched on the important topic of fire performance of engineered wood and its wide use in the modern built environment. Today, we follow up on this subject with Dr Felix Wiesner from the University of Queensland. We leave the (important) topic of compartment fire dynamics and focus on what happens inside the wood in the fire. And there is much more going on than I have initially thought... The transport of moisture, weakening bonds at the glue line and connections, complex...

Who is a Fire Safety Engineer? And when do you become one? How do you know the person on the other side of the table at the project meeting has the necessary competencies to judge fire safety solutions of a building you design? That is a problem with (a) the definition of the profession and (b) the definition of the core competencies related to the profession. And both of these issues are close to the heart of my guest, Jimmy Jönsson, Director at JVVA in Spain and a member of SFPE Board of Direc...

https://firelab.berkeley.edu/ this is the place you need to go! Ignition at different slope angles. Firebrand spotting. Fire whirls. What does connect these various fire phenomena? They are all driven by fluid dynamics and can happen only in very particular flow conditions. To define and understand these conditions... well that is a bit longer story that I will unravel with Prof. Michael J. Gollner of the University of California, Berkeley. In Episode 14 we have gone on a journey through scales ...

Do you sometimes feel that fire safety engineering is not making a footprint as it should? With all our knowledge, models, technology...why do huge fires exist? Why fire is such a threat to billions of humans? In today's episode, I'm hosting a guest who spent three decades researching what performance-based fire safety engineering is, and what it could be. And I'm not completely sure if I like the answers I got from this talk. However, based on my experience of 17 interviews with world-class fir...

There is plenty of fire engineers who think they are modelling human behaviour... Some claim they can do it... And there is very, very few who actually did and succeeded with it. One of them is today's guest, Dr Erica Kuligowski of RMIT University in Melbourne, Australia. After two decades of groundbreaking research at NIST, Erica has moved to Australia to seek new challenges related primarily to the mass evacuation of people during bushfire events. She presents her unique views on modelling hu...

Engineered timber is on a trajectory to become the construction material of the future. However, on that pathway there stands the fire issue. Wood burns, it is inevitable. This is something we must accept, and learn to work around. Common approach – determination of a char profile and the “healthy” section has its limitations, especially when applied to CLT products in which one could expect the glue line failure. And all of this is the topic of my todays discussion with Dr Danny Hopkin of OFR C...

Have you ever wondered who truly has the most power over the fire safety of a building? In my opinion, the answer is very simple - the Architect. This is due to two reasons. First is that the architect can affect the building shape, size, compartmentation, location of the openings in the building - things that are fundamental to the compartment fire dynamics. The second reason is that they make the decisions at the most infant stage of the building construction. When everything is reversible, an...

Have you ever wondered how is a fire of a match or candle different from a wildfire? Or maybe rather, why is it different? What is it, that makes the fires at different scales behave in such a different manner? What are the phenomena that drive these fires, and are these the same phenomena across the scales? These are the questions I had in mind when starting the interview with a rising star of Wildfire Science – Dr Sara McAllister of the USDA Forest Service. Together with Sara we go into a jour...

We are living in a kind of weird time, where the most complex tool we have is at the same time the most commonly used (and abused one). The Computational Fluid Dynamics (CFD) modelling has brought us amazing capabilities in solving the flows within fires. But this power comes at a price - knowledge, resources, time... Sometimes we lack some of these (or all) and we turn the power tool into a generator of beautiful images that are hardly any representation of the physics of the fire... In this ep...

In this episode, I had the pleasure and privilege to host dr Kees Both, the Technical Manager of Standards & Regulations in Etexgroup. Kees wanted to become a suspension bridge engineer, but his route went through a fire lab, and as he said - once you go into a fire lab, there is no way out. From a scientist, he has "evolved" into a research manager, project manager and someone, who has a significant impact on the shape of the standards and legislation in Europe. Kees is also the former Preside...

What is the single most measured thing in fire science? The answer is easy - temperature. We use it everywhere - from learning material properties in TGA's to expressing conditions in compartment fires. We use it at the same time to define exposure conditions for our structures and the acceptance criteria within them. We even use it in evacuation studies to define the tenability criteria for occupants... We measure temperature. Everywhere and all the time. But is it really the thing we are looki...
