Where should you aim a fire extinguisher's stream when extinguishing a fire?

• A. At the top of the fire and use a sweeping motion
• B. At the base of the fire and use a sweeping motion
• C. At the center of the fire to smother it
• D. At the edges of the fire to contain it

Answer: (B)

Aiming a fire extinguisher's stream at the base of the fire is crucial because this is where the fuel source is located. A fire can only be extinguished by eliminating its fuel, and targeting the base ensures that the extinguishing agent effectively reaches the source of the flames. Using a sweeping motion while directing the stream helps to cover the area and ensures that the agent spreads across the fuel source, providing a better chance of putting out the fire completely. This technique is essential in effectively suppressing different types of fires, as it maximizes the contact of the extinguishing agent with the material that is burning. Aiming at the top or center of the fire may seem logical, but it does not address the fuel source directly, which can allow the fire to continue burning or re-ignite. Additionally, targeting the edges of the fire might contain it temporarily, but it does not eliminate the danger since the fuel is still present.
