Firebrand production from structure combustion becomes a key factor in the magnitude of how quickly a large outdoor fire may spread. Post‐fire disaster investigations suggest that attached building components, such as wood fencing assemblies are known to

Wildland-Urban Interface (WUI) incidents are likely to become more severe and will affect more and more people. Given their scale and complexity, WUI incidents require a multi-domain approach to assess their impact and the effectiveness of any mitigation

This report documents the measurement of the wind resistance of different types of vegetation. The measurements are made in a wind tunnel with a 2.0 m test section and 0.5 m by 0.5 m cross- section. Samples of vegetation have been cut into cubical volumes

With more frequent and destructive wildfires occurring in the growing wildland-urban interface (WUI), the ability to ensure the safe evacuation of potentially large groups of people is of increasing importance. This is a challenging task made only more

This report develops an approach to evaluate the direct and indirect impacts from wildland-urban interface (WUI) fires that result in the loss of functionality of the built environment, for a regional economy. While direct losses from WUI fires are largely

The kickoff workshop of the new permanent working group, sponsored by the International Association for Fire Safety Science (IAFSS), entitled Large Outdoor Fires and the Built Environment was held from 3:00 pm to 4:30 pm on Sunday October 21, 2018. The
Large outdoor fires have the potential to negatively impact the built environment. Wildland fires that spread into communities, known as wildland-urban interface (WUI) fires have become a global problem. Large urban fires, including those that have

NIST is currently developing a time-resolved, three-dimensional particle tracking and sizing diagnostic (a.k.a an emberometer) that will be applied to airborne firebrands during wildland- urban interface fires. The present paper provides an overview of
Structures fitted with thatched roofing assemblies are prone to ignition during the course of large outdoor fires. Experiments with thatched roofing assemblies were performed by using a reduced-scale continuous-feed firebrand generator in a wind facility
Firebrands generated from structures are a source of rapid fire spread within communities during large outdoor fires, such as wildland-urban (WUI) fires and urban fires. Though the wind plays an important role during large outdoor fire spread, little known
In a recent urban fire in Itoigawa-city, Niigata, Japan, structures were exposed to firebrands and it was reported roofing assemblies were ignited, which led to loss of entire structures. Roof tiles are fabricated using non-combustible materials yet the
Firebrands generated from structures are known to be a source of rapid flame spread within communities in large outdoor fires, such as wildland-urban (WUI) fires, and urban fires. It is important to better understand firebrand generation mechanism to
