Preparing Homes for Wildfire

The majority of homes ignite in wildfires due to embers and small flames, according to research on home destruction vs. home survival in wildfires. Embers, which are flaming fragments of flying wood and/or plants that can travel over a mile in the wind, can start spot fires and ignite dwellings, debris, and other things.


There are ways for homeowners to prepare their homes to withstand ember attacks and reduce the chances of flames or surface fires impacting the structure or any attachments. Homes ignite due to the state of the home and everything around it, up to 200' from the foundation, according to experiments, models, and post-fire studies. The Home Ignition Zone is what it's called (HIZ).


Following some groundbreaking experimental studies on how dwellings burn due to the impacts of radiant heat, retired USDA Forest Service fire scientist Jack Cohen created the concept of the home ignition zone in the late 1990s. There are three zones in the HIZ. Immediate, Intermediate, and Extended ignition zones.


Learn more about how wildfires spread and ignite home in the National Fire Protection Association's online course Understanding the Wildfire Threat to Homes. An overview of fire history, fire basics, and how homes burn.
