What is the final action in the PASS technique for using a fire extinguisher?

The PASS technique is a systematic approach for using a fire extinguisher effectively and safely. The final action in this technique, which involves sweeping back and forth at the base of the fire, is critical for several reasons.

First, directing the extinguishing agent at the base of the fire ensures that you are targeting the source of the flames rather than the flames themselves. Fires require three elements to sustain themselves: fuel, heat, and oxygen. By applying the extinguishing agent at the base, you disrupt this crucial triangle by cooling the fuel and removing the heat, which is vital for extinguishing the fire.

Additionally, sweeping back and forth allows for better coverage, ensuring that the agent effectively blankets the fire area, thereby preventing the flames from reigniting and promoting a quicker extinguishing effect. This technique maximizes the efficiency of the extinguisher, as simply aiming at the flames can leave part of the fire unaddressed, potentially leading to a resurgence of the fire.

It's important to note that the other options, while they may involve safety measures or preparedness, do not represent the critical final step in the actual process of using a fire extinguisher to put out a fire. They either focus on precautionary measures or logistics unrelated to directly combating
