Question: 1 / 400

Explain the term "ember attack".

A technique used by firefighters to control fires.

A phenomenon where embers ignite materials far from the main fire, posing an increased risk to structures.

The term "ember attack" refers to a phenomenon where burning embers or sparks are carried by wind, igniting materials that are situated far away from the primary source of the fire. This can happen during a wildfire when embers can travel significant distances, often landing on roofs, decks, or dry vegetation, leading to new ignitions in areas that might otherwise be safe from the main fire front.

Understanding ember attack is vital for both fire management strategies and for the protection of structures, as it highlights the need for defensible space and fire-resistant materials in areas susceptible to wildfires. While other choices discuss firefighting techniques or the management of fire spread, they do not capture the specific risk posed by embers that can lead to secondary ignitions, which is a critical aspect of wildfire dynamics.
