Which is the first step in using a portable fire extinguisher?

• A. Aim the nozzle
• B. Squeeze the handle
• C. Pull the pin
• D. Sweep the base

Answer: (C)

Pulling the pin is the first step because it breaks the tamper seal and unlocks the operating lever so you can actually discharge the extinguisher. Without removing the pin, the device remains in safety mode and won’t release the extinguishing agent. Once the pin is out, you can proceed with aiming the nozzle at the base of the fire, squeezing the handle to release the agent, and sweeping from side to side to blanket the flames. This follows the typical PASS sequence: Pull, Aim, Squeeze, Sweep. In real use, act quickly but stay safe, and if the fire is spreading or you’re unsure you can control it, evacuate and call responders.
