Ignitibility of Structural Wood Products Exposed to Embers During Wildland Fires: A Review of Literature   [open pdf - 505KB]

From the Abstract: "The ignitability of structural components due to ember attack is a common cause of the structural fires in wildland-urban interface (WUI) communities. To fire-harden structures in WUI communities, it is important to be able to quantitatively predict the ignitability of wooden substrates in response to ember exposure. To commence this effort, in this manuscript, past studies have been compiled and analyzed to identify the knowledge gaps. Key topics are reviewed, including ignition of structures in WUI fires, measurement of thermal response of solid wood products used in residential structures, controlling mechanisms of ignition and sustained smoldering of wood, measurement of ember properties, real-scale and bench-scale experiments assessing ember ignitability of structural components, and surrogate ignition sources for assessing smoldering propensity of the wooden substrates. Existing standard test methods have also been reviewed in the light of their ability to represent common exposures observed in the WUI environment."
