Halon Fire Extinguisher (red handle): How do you use the fire extinguisher?

• A. Press down on the handle; Aim at the base of the fire; Squeeze lever for discharge operation; Sweep using a side-to-side motion
• B. Pull the pin and press the trigger straight at the flame
• C. Squeeze the lever and sweep over the top of the flames
• D. Ignite the extinguisher and point the spray at the air

Answer: (A)

The main idea is to use the extinguisher in a controlled way that puts the agent where it stops the fire most effectively: at the base of the flames and across the area until it’s out. The best answer describes the proper sequence you typically follow when discharging a handheld extinguisher: activate the discharge, aim at the base of the fire, squeeze the lever to release the agent, and sweep the nozzle from side to side to blanket the fire. Aiming at the base is crucial because you’re starving the fuel and cooling the burning material, not chasing the flames. Sweeping ensures the entire fuel source is covered and helps prevent reignition. The Halon agent is chosen for aircraft because it works quickly on many fire types, including electrical fires, and it leaves no messy residue. Always stand at a safe distance, use short bursts if the fire is small, and back away once it’s out or if it grows beyond control.
