In the PASS technique, what does "sweep" refer to?

The term "sweep" in the PASS technique refers specifically to the action of sweeping the extinguishing agent from side to side at the base of the fire. This method is effective because it helps to cover the area of the fire thoroughly, ensuring that the extinguishing agent is applied directly to the fuel source, which is typically where the flames are originating. By directing the spray in a sweeping motion, the extinguishing agent can disrupt the combustion process and extinguish the fire more effectively.

The focus on the base of the fire is crucial, as applying the agent higher up could allow flames to continue burning and reigniting below. This technique emphasizes a strategic approach to fire fighting that maximizes the impact of the extinguishing agent, leading to a more successful extinguishment. Using a sweeping motion also allows for better control and distribution of the material used, enhancing safety and effectiveness in fire suppression efforts.
