Based on extensive field and lab investigations, the researchers developed a model that predicts the critical distance between homes and sheds required to prevent the ignition of a home when a shed burns. Their findings reveal that the minimum safe distance between a home and a shed depends on several factors, such as:
1. Shed Size: Larger sheds with a greater surface area pose a higher fire risk due to the increased amount of available fuel.
2. Shed Construction: Sheds made of combustible materials, such as wood or plastic, present a higher risk than sheds constructed with non-combustible materials.
3. Vegetation Density: Sheds surrounded by dense vegetation or overhanging branches are more susceptible to wildfires and can act as a bridge for fire spread to the home.
4. Slope and Terrain: Sheds located on steep slopes or in areas with heavy fuel accumulation can accelerate the spread of fire toward the home.
5. Wind Direction and Speed: Prevailing wind direction and wind speed during a wildfire can affect the trajectory of embers, increasing the risk of igniting the home.
The researchers concluded that the minimum safe distance between a home and a shed varies but can be estimated using their model. For typical wood-frame sheds in wildfire-prone regions, the minimum distance ranges from 10 to 50 feet, depending on the specific conditions and factors mentioned above.
This research provides critical insights for homeowners, building code officials, and community planners in wildfire-prone areas. By adopting these guidelines and maintaining a safe distance between homes and sheds, communities can improve their wildfire resilience and reduce the risk of property damage and loss during wildfires.
