Wetting agents as used in this contribution are either water or materials consisting mainly of water. They are used to pre-wet fuels exposed to wildland urban interface fires to prevent ignition and fire spread on these fuels.


Wildland Urban Interface (WUI) fires have become a serious problem affecting most notably California, Colorado, Arizona, Texas, North Carolina, Tennessee, and numerous other states in the United States. These fires occur all over the world. Some of them result in catastrophes destroying a large number of buildings. Three recent examples in the United States include the “Tunnel/Oakland” fire in Oakland, California, in 1991 that destroyed over 2900 homes; the “Old, Cedar, etc.” fire in Southern California in 2003 that destroyed over 3640 homes; the “Witch, Slide, Grass Valley, etc.” fires in Southern California in 2007 that destroyed over 2180 homes (Cohen 2008), and the Chimney Tops 2 fire...
