Sprinkler systems for the protection of buildings from wildfire

Wildfires pose a significant hazard in many residential areas around the world. Minimisation of the risk to human lives and property requires a multi-faceted approach, involving fuel reduction, fire suppression, and engineering measures to improve the resistance of buildings to the effects of intense radiant heat, burning embers and flame contact. Measures that are recommended to improve the wildfire resistance of buildings typically focus on building materials and design features, as well as fuel sources close to the building. Wildfire sprinkler systems are often promoted as an optional, additional risk-mitigation measure. Typically, such systems are designed to spray water on building external surfaces, surround the building with airborne droplets, and/or wet nearby fuel sources during wildfires.
