What is the primary objective of making a rectangular or square cut during firefighting operations?

The primary objective of making a rectangular or square cut during firefighting operations is to avoid cutting through structural supports. This method ensures that the structural integrity of the building is maintained while still allowing for effective ventilation and smoke removal. By carefully planning the cut, firefighters can minimize the risk of causing a collapse or compromising key supports that are essential to the stability of the structure.

In addition to this, making a precise cut helps to create a controlled opening that can lead to safer and more efficient operation in terms of accessing the fire location and ensuring that the heat and smoke escape from the structure, thereby improving visibility and safety for both firefighters and any potential victims inside.
