In vertical ventilation operations, which type of opening is commonly used?

• A. Cable Cut
• B. Higbee Cut
• C. Kerf Cut
• D. Kelly Cut

Answer: (B)

Vertical ventilation relies on creating a rapid, controlled opening in the roof to release heat, smoke, and gases so crews can reach the fire more safely and effectively. The Higbee Cut is designed to produce a ready-to-remove, hinged opening that can be peeled back quickly, giving a large vent with minimal effort and reducing the time firefighters spend cutting. This approach is practical on many roofs because it creates a clean edge and a single removable piece, which speeds up ventilation and helps keep the opening predictable and manageable under heat and smoke conditions. Other cuts exist for different materials or tactical needs, but they’re generally slower or less efficient for achieving a fast, sizable ventilation opening, which is why the Higbee Cut is the commonly taught method.
