In this episode, we delve into the concept of being "qualified" in the workplace, examining who gets labeled as such, who doesn't, and the underlying reasons. We explore "competency checking"—the practice of scrutinizing individuals' abilities—and how it disproportionately affects underrepresented groups, often going unnoticed or unchallenged. Our discussion aims to redefine qualifications in a fair, equitable, and actionable manner. Our guest, Shari Dunn , is an accomplished journalist, former attorney, news anchor, CEO, university professor, and sought-after speaker. She has been recognized as Executive of the Year and a Woman of Influence, with her work appearing in Fortune Magazine, The Wall Street Journal, Ad Age, and more. Her new book, Qualified: How Competency Checking and Race Collide at Work , unpacks what it truly means to be deserving and capable—and why systemic barriers, not personal deficits, are often the real problem. Her insights challenge the narratives that hold so many of us back and offer practical solutions for building a more equitable future. Together, we can build workplaces and communities that don’t just reflect the world we live in, but the one we want to create. A world where being qualified is about recognizing the talent and potential that’s been overlooked for far too long. It’s not just about getting a seat at the table—it’s about building an entirely new table, one designed with space for all of us.

Is evacuation of a community during a wildfire largely different from evacuation of a building? How much of the knowledge from the building fires is directly useful in planning and managing such an event, and what stuff is completely different? These are the lead questions for my today's interview with prof. Enrico Ronchi from Lund University and dr Max Kinateder from National Research Council Canada.

Both guests currently research the evacuation layer of the WUI problem – starting with the response of the endangered people, through choice of the mode of the transport, to solving the transportation models of such evacuations. A multilayered, multifaceted and interdisciplinary challenge, but one we need to have a good understanding of if we want to deliver good risk based, knowledge informed guidance for communities at risk.

In this episode, we got through their research pinpointing the difference between the building and a community evacuation. We touch the methods of research that are currently in used, and what kind of models they can inform. Finally, we get to talk about their recent experimental study during a fire drill in Roxborough Park, Colorado. This has literally happened a few days ago, and we can already discuss the challenges, and the first ‘anecdotal’ findings of the study.

Becoming open to the WUI problem and learning the challenges that are in front of us in this regard is critical to fire safety engineering, especially at the time when we observe Wildfire Safety Engineering becoming more of a real thing! I foresee that in future, a lot of us will work in the wildfire prevention / mitigation/contingency space, and I hope you will appreciate the fact you’ve learned it first from the Fire Science Show!

192 - Fire Fundamentals pt. 14 - Jet fan systems for car parks 42:55

7 days ago42:55

42:55

Jet-fan systems effectively control smoke in car parks by creating directed airflows that transport smoke from one point to another, similar to how longitudinal ventilation works in tunnels. These systems offer cost-effectiveness and simplicity by eliminating ductwork while providing powerful smoke management capabilities when properly designed and understood. • Jet Fans create momentum transfer through air entrainment rather than directly moving smoke • Two distinct operational modes exist: smoke clearance (reducing thermal stress) and smoke control (maintaining clear firefighter access) • Systems require careful balancing of extraction capacity with Jet Fan thrust force • Optimal design typically requires CFD modeling followed by hot smoke testing for verification • Jet Fan activation timing presents challenges for evacuation - usually delayed until occupants exit • Systems excel in tunnel-like geometries but struggle with complex layouts (the "Tetris rule") • Particularly effective against heavier-than-air gases like LPG or EV battery fire emissions • European standards now available through EN 12101 family for design guidance If you need design assistance with Jet Fan systems for your projects, email me directly at w.wegrzynski@itb.pl.

43:14

This episode emphasises the value of focusing on simple things in fire safety engineering, something we somehow miss when we go too deep into the technical details of our projects. I've looked at eight different aspects of fire safety - inspired by the CPR requirements, and I've added resiliency, redundancy and suppression to them. By promoting straightforward guidelines like evaluating material combustibility, ensuring effective egress routes, and engaging with rescue services, architects and engineers can significantly enhance building safety practices. In this episode, we talk about: • Simple methods yield effective fire safety solutions • Importance of adhering to foundational fire safety principles • CPR’s five essential requirements for construction safety • Load-bearing capacity and material combustibility considerations • Strategies for minimising fire spread between structures • Importance of clear egress pathways for building occupants • Opportunities for enhancing rescue team safety via communication • Emphasis on redundancy and resiliency in fire safety systems Each foundational principle allows fire safety practitioners to implement effective strategies that can lead to safer buildings and improved occupant outcomes.

187 - Smouldering of preserved timber with Wenxuan Wu 55:26

6 weeks ago55:26

55:26

Can a tiny amount of bio-protective coating completely change the fire behaviour of mass timber logs? If you asked me that some time ago, I would say it would probably be neutral. Can a 0.5 x 0.5 m free-standing log of timber smoulder through without any external exposure to fire? If you asked me that some time ago, I would say no, and base that on observations of dozens of logs like this. Yet, in Australia they’ve burned. And the hypothesis was that it has something to do with the preservative treatment. My guest today, Wenxuan Wu from The University of Queensland was tasked with researching this problem and showed us the workshop used for this. In this podcast episode, we dive deep into measurements carried out in fire laboratories on the material scale and how use of different methods gradually increases our understanding of the problem. Their pursuit also opened new questsions - for example, why if timber would be subject to a very strong heat flux, the smouldering would not work anymore? This was also answered in the discussion. If you would like to learn more about Wenxuan’s research, please refer to the published papers: Experimental study on the factors affecting smouldering behaviour of CCA-treated wood Deactivation of chromated copper arsenate as a catalyst in smouldering of wood Also, this talk summarises the best poster at ITB-FRISSBE Summer School.

186 - Egressibility: a paradigm shift in evacuation research with Enrico Ronchi 1:02:52

7 weeks ago1:02:52

1:02:52

If we truly want to account for the population at a disadvantage in evacuation, there is only this much we can do with the current approach... Pre-evacuation time distributions, walking speeds, and so on only tell us a part of the story - the story of your average person within an average population, with an average walking speed and average response. While these models are undoubtedly useful in engineering, there is perhaps a better way. My friend and guest Enrico Ronchi is trying to find this way through his new ERC Consolidator grant, "Egressibility: a paradigm shift in evacuation research". In this grant, instead of following the main path, he is focusing on stuff we do not know - how to characterise disabilities and understand them better (also through the lens of health and medicine), how to quantify the disadvantages at large, and how to solve potential issues for those who those at the largest risk. In this episode, you will learn about Enrico's ideas and the edge of the knowledge we have today. Some key points covered are: • Insights on paradigm shifts in evacuation science • Introduction of the concept of "egressibility" • Importance of understanding functional limitations in emergencies • Shift from agent-based models to inclusive data-driven models • Use of technology, like VR, for immersive research experiences • Need for changes in regulations for better evacuation safety You may also like to read the paper by Guylène Proulx, which introduced egressibility as a concept - available here.

In the aftermath of the LA Pacific Palisades Fire, I've decided that instead of inviting one expert to discuss the event, I will give a voice back to those who already participated in the Fire Science Show and explained this fire (months and years before it happened). In this episode, we recap Wildland-Urban Interface fires, with a focus on the "urban" part. We cover conditions in which such fires may happen and factors that contribute. We discuss the role of community preparedness and pathways in how those fires "attack" individual households. We talk a lot about embers and some ideas on how to mitigate them. Finally, we discuss the evacuation from WUI fires. Some politics, a lot of science, decent amount of answers to most urgent questions. I hope you will enjoy!

1:01:19

History repeats itself. A new thing is invented. We learn about it, understand it, and apply measures to capture its behaviour and regulate it. And then another new thing is invented. The measures we used start failing us, and the cycle repeats all over again. It is not a story of fire safety; it is a story of humanity. Similar cycles can be observed in all aspects of technology. One could call them Innovation Blind Spots after Prof. Rein; in science, you could call them paradigm shifts after Prof. Kuhn. Regardless, these cycles are the frame we work in, and we need to learn to handle them. In fire safety, they are often a cause of major disasters. In this podcast episode, I once again interview prof. Vincent Brannigan. Vincent has spent a large part of his career studying the limiting factors of innovation in fire science and its regulation. This podcast is framed after a lecture Vincent delivered 15 years ago, which can be accessed here: https://www.fireseat.eng.ed.ac.uk/sites/fireseat.eng.ed.ac.uk/files/images/02-Brannigan.pdf It is an engaging read, I recommend going through it after the podcast episode!

182 - Bias in fire research 45:58

13 weeks ago45:58

45:58

Fire is a highly contextualized problem; therefore, there is no such thing as an unbiased or "objective" fire experiment. It is a thing that many researchers would understand but is very rarely pointed out. Where it is not a problem for fire science (more like a 'feature'), it may become one when the results of scientific experiments are directly applied to real-world engineering cases. In this episode, I cover biases in research, from general ones to highly specific fire safety engineering biases. The list is long, we cover: selection bias confirmation bias measurement/instrumentation bias publication bias observer bias sampling/data analysis bias conflicts of interests We also discuss the contextual nature of fire and fire science related to architecture, fuel, ignition, and environmental conditions. We cover experimental design and measurement techniques. While showcasing all those possible sources of uncertainty and error, it is important to highlight that the science is generally very reliable—you just need to know how to use it. This is the final episode of 2024, so thank you very much for being here with the Fire Science Show and see you back on the Jan 8th 2025!!! Merry Christmas and a Happy New Year to all of you!

58:15

I just drove 500 km to have a conversation with Professor Vincent Brannigan from the University of Maryland, a very unique expert who combines law with fire engineering. In this discussion, we go into the complexities of building codes and fire safety, comparing traditional design methods (prescriptive) with performance-based designs (and all the stuff in between them). Through anecdotes and historical fire incidents, we highlight the impact of these systems on societal safety, economic development, and international trade. Vincent's unique background in both law and technology provides a rich perspective on how fire safety regulations have evolved to meet contemporary challenges. In the episode, we explore the ongoing shift from politically validated regulations to those grounded in technical knowledge. This transition parallels developments in fields like medicine, necessitating a higher level of precision and expertise in ensuring public safety. We also tackle the thorny issue of global standardization, examining how experiential knowledge and political influences shape fire safety laws worldwide. Finally, the episode dives deep into the challenges of balancing innovation and compliance in building safety. With examples from the world of hotels, airports and tall buildings, we discuss the role of engineers and regulators in navigating complex safety landscapes. Historical case studies, like the Triangle Shirtwaist fire, serve as poignant reminders of the stakes involved. Listen in for a thought-provoking exploration of risk analysis, regulatory negotiations, and the constant evolution of fire safety standards as we seek to protect lives and foster innovation.

In this episode of fire science fundamentals, we cover the pressurisation systems. These are smoke control solutions used to prevent smoke from accessing protected spaces, by creating an overpressure in those spaces. Although the idea is very simple, its execution is far from that. Pressurization systems need to work in two distinct states – when all doors to the protected space are closed (over pressurization state), and when some openings are open (flow-path state). In this episode, we cover: · What are pressurization systems and why do we use them in buildings; · Static and dynamic pressure; · Pressurization systems as part of the smoke control strategy; · Old-type mechanical systems, and novel active control systems; · Role of vestibules/lobbies in resiliency strategy; · Practical examples of use; · Testing and certification.
