When conducting a transitional attack on an attic fire, directing streams through soffit vents is an effective strategy because it allows firefighters to reach the fire with water while minimizing the potential for rapid fire spread and backdraft situations. Soffit vents are openings located under the eaves of the roof and provide access to the area where fires can often rage undetected.

By targeting the fire directly through these vents, firefighters can apply water directly where it is needed without having to enter the structure. This method also helps to cool the superheated gases above the fire, potentially decreasing the risk of flashover and improving visibility for subsequent fire suppression operations.

Using soffit vents maximizes the effectiveness of the water stream by taking advantage of the natural path of the fire’s heat and smoke upward, thereby providing better conditions for both attacking the fire and ensuring firefighters' safety.
