Description
Have you ever wondered how is a fire of a match or candle different from a wildfire? Or maybe rather, why is it different? What is it, that makes the fires at different scales behave in such a different manner? What are the phenomena that drive these fires, and are these the same phenomena across the scales? These are the questions I had in mind when starting the interview with a rising star of Wildfire Science – Dr Sara McAllister of the USDA Forest Service. Together with Sara we go into a journey across the scales of fire phenomena, discussing what are the key phenomena at particular scales. From matchsticks, through cribs and compartment fires, to wildfires and megafires – probably the most comprehensive discussion on the scales of fire phenomena I’ve ever had. From this episode you will also learn a lot about burning down wood cribs and about the LOF&BE initiative within the International Association for Fire Safety Science.
