When using the three cut method on a door, how far down from the top should the third cut be made?

The three cut method for ventilating a door involves making a series of cuts to create openings that allow heat and smoke to escape. The third cut, which is the bottom cut, should be made two feet down from the top of the door. This height is effective for several reasons.

First, making the cut two feet down helps ensure that the top cut allows heat and smoke to vent effectively while also maintaining structural integrity in the door and avoiding unnecessary compromise of its stability. Additionally, placing the cut at this height creates a sufficient gap for the release of gases without making the opening too low, which could lead to complications when attempting to manage the flow path or when transitioning through the door.

Understanding the appropriate placement of cuts is crucial in fire operations, as it directly affects the overall ventilation process and the safety of the firefighting team. This practice promotes better efficiency and enhances the safety measures taken during an operation.
