What type of fire is caused by flying embers that starts outside the perimeter of the main fire?

The type of fire caused by flying embers that ignites outside the main fire's perimeter is referred to as a spot fire. This phenomenon occurs when small, burning particles or embers are carried by wind or other forces to a location away from the main fire, where they can ignite combustible materials. Spot fires are particularly significant in wildland fire situations, as they can spread quickly and create additional challenges for firefighting efforts.

Understanding spot fires is crucial for firefighters because they indicate the potential for a fire to expand beyond its initial boundaries, necessitating prompt action to contain the threat. Recognizing the behavior of spot fires helps firefighters implement effective strategies to mitigate risks and protect surrounding areas.
