Which technique is often utilized for victim searching in a smoke-filled environment?

In a smoke-filled environment, low crawling is often utilized as an effective technique for victim searching. This method is beneficial because it allows firefighters to stay close to the ground where visibility is generally better due to the fact that smoke rises. The air closest to the floor tends to be cooler and less dense, making it easier to breathe and navigate. Low crawling also minimizes exposure to hot gases and potential hazards that may be present in the smoke layer.

In this scenario, firefighters can use their hands to feel for victims or obstacles, enhancing their ability to locate individuals who may be incapacitated or in need of assistance. This technique is critical in ensuring safety during operations in highly hazardous conditions where visibility is compromised.
