188 - Fire Fundamentals pt. 13 - Porous solid fuels
In this episode of Fire Fundamentals, together with Dr Sara McAllister, we dwell on how stuff burns... And it is far from an easy question. While the general theme of the episodes is porous fuels, we discuss them from differe...

187 - Smouldering of preserved timber with Wenxuan Wu
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...

186 - Egressibility: a paradigm shift in evacuation research with Enrico Ronchi
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 o...

185 - Recap on wildfire science
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 ...

184 - Cost-benefit analysis in structural fire safety with Thomas Gernay and Chenzi Ma
This episode delves into the financial aspects of fire safety in building design, highlighting the balance between cost and effectiveness. My guests - prof. Thomas Gernay and Chenzi Ma from Johns Hopkins University share insi...

183 - Innovation and fire safety with Vincent Brannigan
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, an...

182 - Bias in fire research
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 ...

181 - Regulatory regimes with Vincent Brannigan
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 buil...

180 - Fire Fundamentals pt. 12 - Pressurization systems
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...

177 - Physics-Based Modelling of Fire Spread with Francesco Restuccia
Wildfire modelling is quite complicated when you wish to integrate different fuel packages with different properties in 'real' environmental conditions while managing the transition to/from smouldering. We have a model for ea...

176 - The Myth of Panic with Daniel Nilsson
You are not supposed to use the word 'panic' in the context of human behaviour in fires, yet this episode contains 196 instances of it. Why? because we try to get to the bottom of the thing! Can panic be both a myth and a rea...

175 - Changes in the UK fire regulations with Dame Judith Hackitt
The Grenfell Tower tragedy has triggered a Public Inquiry (which just published their final report ), and concurrently - a review of the UK Building Regulations and Fire Safety. The latter task was given to Dame Judith Hackit...
