In an emergency, which action is the correct direction of aiming when using a fire extinguisher?

• A. At the base of the flames
• B. At the top of the flames
• C. At the side of the flames
• D. At the heat source

Answer: (A)

A fire extinguisher works best when you apply the extinguishing agent to the base of the flames, where the fuel is actually feeding the fire. By aiming at the base, the agent cools the burning material and interrupts the flame front at its source, preventing the fire from continuing to spread. Aiming at the top or the sides doesn’t stop the fuel from feeding the flames, and aiming at the heat source isn’t how the agent is designed to work and can be unsafe. In practice, you would aim at the base and sweep the agent across the base area to knock the fire down, continuing until it’s fully out or you must retreat to safety.
