Protecting Homes from Wildfires

This online engineering PDH course introduces the principles and practices of home construction in wildfire zones. No building can be completely fireproof, but implementing the recommendations that are described in this course can greatly reduce the potential for damage to a building and greatly increase its chance of survival.

Wildfires are a common, natural, and essential occurrence in the forests, woodlands, brushlands, and grasslands of the United States and Canada. When conditions are acceptable, fire professionals use fire to revitalize the ecosystem and reduce accumulated vegetation that can fuel a wildfire under certain conditions. Although the severity and timing of fire seasons vary widely from region to region, wildfires often pose a threat to lives, property, and resources.

Wildfires can damage buildings through direct flame contact, convection (heat that rises from a fire and creates a smoke column), conduction (heat that transfers through material such as metal roofs and railings), and radiation (heat from a fire next to the building). Wildfires can also create burning embers that rise in the smoke column and fall on buildings. Firebrands (large pieces of wind-driven, burning material) can be blown through windows or lodged against a building and lead to ignition of the building.

Traditional efforts to protect buildings from wildfires have focused on fighting the fire before it reaches the buildings. With the expansion of residential construction into previously undeveloped forests and wildlands, more buildings are now at risk from wildfires. Since fighting or suppressing the fire is often difficult or impractical; buildings must therefore also be constructed to be fire-resistant.

This 8 PDH course is intended for engineers and architects who are interested in gaining an understanding of how to protect homes from wildfires.
