Southwest Airlines (SWA) Test 2 Practice

The correct approach when using a halon extinguisher is to aim at the base of the flame using a sweeping motion. This is because the base of the flame is where the fuel is ignited, and targeting this area is essential for effectively extinguishing the fire. By applying the agent at the base, it interrupts the chemical reaction of combustion and helps to smother the fire before it can spread.

Aiming at the top of the flame would not effectively extinguish it, as this part is often where the gases and heat rise. Similarly, directing the extinguisher directly at the burning item may not effectively cut off the fire's access to fuel. Lastly, using a circular motion around the flame might not focus the extinguishing agent where it is most needed, potentially allowing the fire to continue burning.

Therefore, by focusing the application of the halon at the base of the flames with a sweeping motion, you maximize the effectiveness of the extinguisher and improve your chances of successfully putting out the fire.
