Which action is performed first when using a fire extinguisher?

• A. Aim
• B. Pull
• C. Squeeze
• D. Sweep

Answer: (B)

Pulling the safety pin is the first action because it removes the tamper seal and unlocks the discharge mechanism. Without pulling the pin, the extinguisher won’t release any agent, even if you squeeze the handle or aim. After the pin is removed, you aim at the base of the fire, squeeze the handle to release the extinguishing agent, and sweep from side to side to blanket the flames. The pin’s role as a safeguard against accidental discharge is why it must come first, then the remaining steps follow in order to suppress the fire effectively.
