Where should one aim to remove oxygen from a fire?

Aiming to remove oxygen from a fire by targeting the base is the correct approach because this is where the combustion process is most concentrated. The base of the fire is where the fuel, heat, and oxygen come together, creating the necessary conditions for flames to develop and spread. By effectively applying an extinguishing agent at the base, it can suffocate the flames and cut off the oxygen supply, disrupting the fire’s ability to sustain itself.

This method is more effective than aiming at the flames themselves, as doing so may only briefly disturb the flames without addressing the source of combustion. Targeting the smoke does not directly impact the oxygen available to the fire and can often result in ineffective suppression. Similarly, aiming at the surrounding area does not focus on the fire’s origin point, which is crucial for extinguishing the fire efficiently. Therefore, directing efforts at the base maximizes the chances of extinguishing the fire effectively.
