When using a fire extinguisher you should always aim the nozzle

At the flames directly
At the flames indirectly
At the top of the flames
At the base of the flames

The correct answer is: At the base of the flames

Aiming the nozzle at the base of the flames is crucial when using a fire extinguisher. This technique targets the source of the fire, which is where the flammable material is located, allowing the extinguishing agent to effectively disrupt the combustion process. By focusing on the base, you eliminate the fuel that is sustaining the fire instead of merely displacing the flames, which may not be effective. While directing the nozzle at the flames or their top might produce a visual impact, it is not effective in extinguishing the fire. Indirect aiming also lacks the necessary focus on the fuel source and may lead to a prolonged fire situation. Therefore, aiming at the base is the most effective strategy for extinguishing a fire quickly and safely.
