What is the purpose of using a pike pole or Halligan during vertical ventilation?

• A. To measure wind speed
• B. To communicate with incident commander
• C. To clear decking debris, probe for fire extension, and assist in creating or enlarging openings
• D. To cut metal flashing

Answer: (C)

During vertical ventilation, the goal is to establish a clear, accessible vent path and determine if fire is spreading behind the decking. A pike pole and a Halligan are multipurpose tools that enable this in several practical ways. The pike pole is long and geared for reaching up to the roof deck to push, pull, and rake away debris that can block the opening or trap heat and smoke. The Halligan bar is used to pry, lift, and chip away at decking or roofing materials, helping to create or enlarge the opening and to manage the roof’s structure so the vent path stays safe and accessible. Together, these tools allow firefighters to clear obstructions, probe for fire extension behind the roof or between floors, and shape the opening so venting will be effective.

Choosing these tools over options like measuring wind speed, communicating with the incident commander, or cutting metal flashing aligns with their real-world purpose: they’re about physically preparing and maintaining the vent path, not measurement, radio communication, or metal cutting.
