CROSS UK is Collaborative Reporting for Safer Structures in UK. CROSS is a confidential reporting system which allows professionals working in the built environment to report on fire and structural safety issues. These are then published anonymously to share lessons learned, create positive change, and improve safety. Find out more about the safety information we provide below. This initiative in the space of fire safety is lead by Neil Gibbins and Peter Wilkinson, who are my guests today. We go through the ideas behind the institution and the reasons why we need it. We discuss the confidentia ..read more

In this episode of the Fire Science Show we go in depth on the Building Integrated Photo-Voltaic systems (BIPV). It is a topic relevant to many fire engineers, and one on which it is very difficult to find a lot of information about. For this purpose I’ve invited Reidar Stølen from RISE and a PhD candidate at Norwegian University of Science and Technology – NTNU. Reidar has hands-on experience with fire testing BIPV façade, as he has performed such experiments with the Swedish test method for a commercial project. The results of the first experiments can be found in this research paper: Large ..read more

In this episode, we explore wildfire's impact on industrial fire safety with Professor Eulàlia Planas from Universitat Politécnica de Catalunya. Eulalia defines the term  Wildland Industrial Interface (WII), a realm where the forces of nature clash with safety and process engineering. In the episode, we highlight that it is not just the exposure to the fire itself but also to the secondary effects - ember storms, firebrand accumulation, strong winds or power shutdowns that may cause significant damage. Also, even if the wildfires do not cause fires directly, they may damage auxiliary sys ..read more

Depression and anxiety are on the rise in both academia and engineering consultancies. Everyone is constantly stressed and pushed to their limits. The system is built this way... And imagine that on top of the inadequate mental health related to the stressful environment, you also struggle with a mental illness. A health condition you did not choose, you may or may not be aware of, and may or may not be treating... Now, add trying to build a family and advance the most challenging part of the academic ladder. All of these are elements of the story of today's guest - Professor Ann Jeffers of th ..read more

In this episode, we discuss the stark realities of fire safety engineering in South Africa (and beyond) as we sit down with Professor Richard Walls from Stellenbosch University. Our journey through the recent history of devastating fires, from truck blasts to the fire that took down the SA Parliament building, lays bare the critical gaps in resources, awareness and education that have catastrophic consequences.  Professor Walls's expertise guides us through the complexities of local building codes and the vital role of education in fostering fire safety competency in the country. We diss ..read more

Imagine if we had a tool that we could use to design a design fire. Instead of simply assuming fire growth characteristics by slapping the alpha-t2 function, use a tool that could tell us which items in a compartment burn and what the characteristics of that fire are. I would say this dream is shared among many fire safety engineers - I think we can all agree that we could use such a tool. Today's guest, Dr Greg Baker, has shared this dream and built a tool like this within his PhD at the University of Canterbury. The skeleton was a zone model, and the tool developed has played with it well ..read more

In today's fire fundamentals episode, I have chosen a difficult job: explaining how CFD modelling works without the ability to put a single equation out there! It's much tougher than I thought! I hope I've done a decent job, though. I am trying to fill out this niche of talking about CFD at an approachable level. I've noticed there is a ton of 'introductory' level resources about modeling. Still, they usually very quickly go into mathematical formulations instead of explaining in plain language what is the purpose of specific models or modelling approaches. In this episode, you will learn ab ..read more

If the word 'uncertainty' sounds extremely boring to you, this episode will prove you wrong. I have invited David Morrisset from the University of Edinburgh to discuss his research on the subject. Whereas in fact David is establishing standard deviations, means and other statistical means of quantifying uncertainty in core fire measurements, the really impactful and important part of his research is on explaining WHY those uncertainties are there. Through physical explanation of processes happening in fire we may grasp a really good understanding why two HRR-time curves of the same object burn ..read more

This week, I am meeting up with Imperial Hazelab's Harry Mitchell, who is finalizing his PhD thesis on mass timber fires and, quite uniquely - including the smouldering phenomena in those fires. As a part of Code Red experiments run by Arup, Imperial College London and Cerib (which you can learn more about from episode 111 with Panos Kotsovinos)  Harry has performed observations of formation, growth and decay of smouldering "hot spots" for up to 2 days after the fire. Based on that, conclusions were formed on the occurrence and persistence of the smouldering in large, open-plan mass timb ..read more
