What should be checked to see if the structure has potential ember traps?

The identification of potential ember traps is crucial in assessing a structure's vulnerability to wildfires. Open vents, specifically those that are not properly screened or designed to prevent embers from entering, can allow embers to infiltrate attics or crawl spaces. This poses a significant risk, as embers can ignite combustible materials inside the structure, leading to potential fire spread.

In wildfire-prone areas, it is important to ensure that vents have protective measures in place, such as screens with a mesh size small enough to block the entry of embers. Ensuring that vents are adequately covered and designed to minimize the risk of ember intrusion is an essential step in enhancing the fire resilience of a building.

While aspects like roof pitch, construction materials, and surrounding trees are important in the context of wildfire preparedness, they do not directly relate to the specific issue of ember traps as open vents do. Therefore, focusing on open vents provides a targeted approach to mitigating ember-related risks.
