Abstract:
Firebrands or embers are produced as trees and
structures burn in wildland/urban interface (WUI) fires.
Hot firebrands ultimately come to rest and may ignite
fuels far removed from the fire, resulting in fire
spread. It is believed that firebrand showers created in
WUI fires may ignite vegetation and mulch located near
homes and structures. This, in turn, may lead to
ignition of homes and structures due to burning
vegetation and mulch. Understanding these ignition
events due to firebrands are important to mitigate fire
spread in communities.
