Abstract

Large outdoor fires present a risk to the built environment. One example often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. Another example are large urban fires including those that have occurred after earthquakes. Firebrands are a key mechanism on how rapidly fires spread in these types of fires, as was observed in the 2016 Itoigawa City Fire in Niigata, Japan. To this end, an experimental protocol has been developed to ignite full-scale roofing assemblies and quantify the degree of firebrand production during the combustion process. As wind is an important factor in firebrand generation, the experiments were conducted under a range of wind speeds at the Building Research Institute's (BRI) Fire Research Wind Tunnel Facility (FRWTF). Results of these experiments will be presented and discussed
