What is the PASS technique for using a fire extinguisher?

• A. Push the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.
• B. Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.
• C. Pull the pin, Alert the supervisor, Squeeze the handle, Sweep side to side.
• D. Pull the pin, Aim, Spin, Sweep

Answer: (B)

Using a fire extinguisher effectively hinges on the PASS method: pull the pin, aim at the base of the fire, squeeze the handle, and sweep from side to side. Pulling the pin releases the safety mechanism so you can operate the lever. Aiming at the base targets the fuel source rather than the flames, making the extinguishing action more effective. Squeezing releases the extinguishing agent, and sweeping across the base covers the area, cooling the fuel surface and helping prevent re-ignition. The other options omit or alter these essential steps—for example, pushing the pin instead of pulling, or adding actions like alerting someone or spinning, which aren’t part of the proper technique. If the fire is small and contained, follow PASS to suppress it; if not, evacuate and call for help.
