What is the second step in the PASS method for using a fire extinguisher?

• A. Pull the pin
• B. Aim at the base of the fire
• C. Squeeze the trigger
• D. Sweep side to side

Answer: (B)

The second step in PASS is aiming at the base of the fire. After you pull the pin to break the tamper seal and prepare the extinguisher, you want the extinguisher’s agent to meet the fuel source, not just the flames. Directing the spray at the base targets the material that’s burning, helping to cool or smother it and interrupt the fire’s source of heat. If you aim at the flames or the top, the agent may not reach the fuel surface effectively, and the fire could continue or re-ignite. After aiming, you squeeze to release the agent and then sweep from side to side to cover the area and ensure all burning material is treated.
