In an aggressive fog attack, where should the fog bursts be applied?

Applying fog bursts into the upper gas layer during an aggressive fog attack is essential for effectively cooling the heated gases and controlling the fire. Fires produce a significant amount of heat, causing the smoke and gas layers above the seat of the fire to rise. By targeting these upper layers with fog, you can displace the superheated gases and reduce the overall temperature, effectively lowering the risk of flashover and improving visibility.

In this scenario, focusing on the obstacles created by the fire, like smoke and heat above, allows firefighters to create a safer and more manageable environment for potential rescue operations and tactics to extinguish the fire. Directing the fog into the upper layers can also help break the thermal layer and promote better fire suppression techniques.

In contrast, targeting the seat of the fire or along the floor may not adequately address the rising heat and smoke that is critical in managing the fire. Similarly, approaching flammable liquids without addressing the upper gas layer can lead to explosive situations, making it crucial to recognize the behavior of fire gases in an aggressive fog attack approach.
