fire behavior 2 homeowners brochure

Research shows that a FIREWISE prepared house with a surrounding FIREWISE Defensible Space is 85% more likely to survive a wildfire than one that is not prepared.


Understanding fire behavior, especially how hot a fire will be and how long it will be at the building site, will help homeowners and builders decide how defensible a house needs to be, and what actions need to be taken to make the building site more fire-resistive.

Four principal factors are responsible

for structure ignitions:

*  Indirect heating by convection

*  Firebrands (airborne burning embers)

*  Indirect heating by radiation

*  Direct flame contact or impingement
