Fire Science Show

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. ---- The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

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.

Discover the hidden backbone of fire safety with assurance industry expert Abhishek Chhabra as we unravel the essential frameworks that keep our buildings safe and sound. We explore the vital role of standards, accreditations, and testing mechanisms in fostering trust and compliance within the construction industry. It is not easy to talk about, but I assure you (pun intended) that Abhishek can talk about it in an engaging and fun way. Gain a deeper understanding of the current landscape of fire safety engineering, where an urgent demand for robust credential assurance matches the scarcity of professionals. Delve into the complexities of establishing a comprehensive competence regime for the industry. Learn why the accuracy and repeatability of fire testing methods are indispensable in maintaining market trust and product safety. Through our conversation, we highlight the critical need for standards like ISO 17024, ISO 17025, ISO 17020 and 17065, ensuring that everyone, from designers to facility managers, is equipped with the necessary certifications. As global safety standards evolve, the distinction between liability and responsibility becomes increasingly crucial.  At the end of the episode, we also discuss performance-based design and the potentially transformative role of laboratories and inspection bodies in developing custom solutions, addressing the unique challenges of innovative engineering projects. Join us as we explore the vital importance of testing in delivering reliable performance outcomes, particularly in an era when safety cannot be compromised. ---- The Fire Science Show is produced by the Fire Science Media in collaboration with OFR Consultants.

Happy 200th birthday, Scottish Fire and Rescue Services!!! I'm a bit late to the party. Still, I've done my best to celebrate your anniversary in the best way I can - by giving homage to the amazing fire safety engineering and firefighting that came out of Edinburgh and your founder, James Braidwood. In this episode, we tap into the secrets of early fire safety measures and discover the fascinating history of firefighting with our guest, Michał Stachowicz, a dedicated Scottish firefighter. We promise you'll gain a newfound appreciation for the roots of fire engineering, which surprisingly predate the establishment of professional firefighting. From the early codifications of the 1400s to the impactful Great Fire of London in 1666, this episode is brimming with riveting tales and historical insights into the evolution of fire protection in the UK. We take a journey through time as we contrast the altruism of today's firefighters with the profit-driven origins of fire protection, shaped significantly by insurance companies. Learn about the preventative measures that were set in place long before formal fire services existed, including the fascinating use of historical firewalls in cities like Copenhagen. We also explore the pioneering efforts of James Braidwood, whose revolutionary work in risk management and fire prevention set the stage for organised firefighting in Edinburgh and London during the 19th century. Join us as we honour Braidwood's legacy and his transformative impact on fire safety regulations and practices. From his groundbreaking techniques, such as early personal protective equipment and strategic fire station placements, to his radical ideas on fire spread prevention, Braidwood's forward-thinking approach remains influential. Despite facing financial hurdles and limited cooperation, his vision for a unified fire service prevailed, underscoring the enduring significance of his contributions. Michał Stachowicz helps us celebrate the indelible mark Braidwood left on the firefighting community, offering a compelling narrative for history enthusiasts and fire safety advocates alike.

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 each, but how do we make them work in unison without relying too much on their users' skills? This is a subject for a good research grant... a very big one. And this is something 'we' just got! A fire scientist from King's College London, Dr Francesco Restuccia, has just secured an ERC grant for his innovative project on wildfire modelling. The project name is Wildfires and Climate Change: Physics-Based Modelling of Fire Spread in a Changing World. In this podcast episode, we will discuss his current focus on developing physics-based models that promise to enhance our understanding of wildfire dynamics. We also focus on Francesco's current experience in batteries and how that experience translates to the work he is carrying out in the wildfires. Throughout the episode, we explore the diverse range of models that predict wildfire behaviour, from straightforward empirical approaches to intricate physics-based simulations. We dive into the complexities of balancing ease of use with accuracy and discuss the exciting potential of reduced-order models that blend empirical data with physical insights. Dr. Restuccia offers a unique perspective on the challenges of automating complex models for broader applications and the necessity of identifying fire regimes to ensure precision is not compromised. Dr. Restuccia also shares invaluable insights into securing an ERC grant, guiding aspiring researchers. From refining research ideas into a cohesive project to preparing for the competitive interview process, his experience underscores the importance of mentorship and strategic planning. We wrap up with a look at the future possibilities his research holds for fire safety engineering, inviting listeners to explore the transformative impact of advanced wildfire modelling on a global scale.
