My name is Wojciech Węgrzyński. I'm a professor at the Building Research Institute in Poland, a fire safety engineer, and an enthusiast for fire. In my podcast, Fire Science Show, I interview experts in the field every week on the newest and best knowledge about fire. Catering to fresh and seasoned engineers, it provides unparalleled professional development for any practising FSE. In this podcast, I am joining HALLIWELL Fire Research to provide a more fundamental insight into fire science. Wit...

In this mini-series of the Uncovered Witness - Fire Science Revelations, we cover the subject of the means of escape - the technical solutions in our buildings meant to allow for human evacuation in case of a fire. In the third and final episode of the mini-series, we discuss what makes or breaks the design of an evacuation sign. While it may seem like a simple design choice (make it green and make the arrow point in the correct direction?), there are, in fact, many elements that influence the ...

In this mini-series of the Uncovered Witness - Fire Science Revelations, we cover the subject of the means of escape - the technical solutions in our buildings meant to allow for human evacuation in case of a fire. In the second episode of this mini-series, we cover the fire engineering solutions for building automation that influence the evacuation processes in the buildings. Reflecting on the Beverly Hills Supper Club tragedy, where the systems were not present, we try to evaluate what tools ...

In this mini-series of the Uncovered Witness - Fire Science Revelations, we cover the subject of the means of escape - the technical solutions in our buildings meant to allow for human evacuation in case of a fire. In the first episode of the series, we discuss exit capacities and flow rates. How do we know how many people can fit in the building? What do the models look like, and where did they come from? What data do we have at our disposal, and how relevant is it? We also refer to the tragi...

In this episode of The Uncovered Witness, I've invited Kristen E. Lange from Ogden Murphy Wallace P.L.L.C. In her expertise, Kristen has worked on court cases related to fire safety; in those cases, she has worked with expert witnesses who were fire safety engineers. Trying to tap into this experience, we try to identify "who" is the expert witness? What role are they in legal proceedings, and how is their expertise presented? Also, what makes an outstanding expert witness? This show is produ...

Welcome to Season 2 of Uncovered Witness: Fire Science Revelations! This season, the show's theme is Humans as part of a fire safety engineered system. In this series, we will unravel our understanding of human behaviour in fires and how this complex behaviour may be accounted for in the fire-safe design of buildings. Our understanding of the occupant response, decision-making process and biases may influence our design of exits and improve (or impede) the egress process. In the final episode o...

In this episode of 'Uncovered Witness: Fire Science Revelations,' we investigate the complexities of identifying and fixing building defects. The episode begins by outlining the stages involved, from the initial detection of a defect to selecting an appropriate fix. The host highlights the roles and responsibilities of key stakeholders such as developers and insurers, highlighting the challenges of defining what constitutes a defect and determining whether insurance policies cover it. Early resp...

This episode of Uncovered Witness: Fire Science Revelations, Season 3, delves into the challenging process of defining and identifying building defects, particularly in the realm of fire safety. We emphasize the complexity and multifaceted nature of what constitutes a building defect. Joined by experts from various disciplines, including fire safety, law, and insurance, the episode unravels different perspectives on defects, their implications, and their compliance with building regulations. Th...

Welcome to the third season of Uncovered Witness: Fire Science Revelations. In the third season, the focus shifts from a purely technical analysis of building design and fire safety measures to an understanding of the intricate legal and regulatory landscapes that govern compliance. Across four in-depth episodes, experts in law, engineering, insurance, and forensic fire research collectively shed light on how buildings achieve (or fail to achieve) legal compliance and genuine safety. These conv...

In the final episode of "Uncovered Witness: Fire Science Revelations," Season 3, the series explores how defects can arise, the multidisciplinary approach needed to address them, and the pivotal role of loss adjusters and expert witnesses in resolving such conflicts. The process begins with identifying the building defect, which is not merely about identifying something built incorrectly but involves complex definitions based on legal and insurance policies, potential dangers, and regulatory com...
