For which type of occupancy is the 7, 9, 8 rectangular cut best suited?

The 7, 9, 8 rectangular cut is particularly effective for large commercial occupancies due to its functionality in providing quick and efficient access to the building’s interior. Large commercial buildings typically have extensive and complex roof structures, which require a method that allows firefighters to safely and effectively ventilate the area beneath the roof. The rectangular cut facilitates better airflow and helps to remove heat, smoke, and toxic gases from the structure, ensuring improved conditions for both occupants and firefighters within the building.

This method is advantageous in large spaces where the volume of smoke and heat can rapidly accumulate. By employing a 7, 9, 8 cut, responders can create a large enough opening that maximizes ventilation effectiveness while also controlling the entry point to prevent the situation from worsening. In contrast, the other types of occupancies, such as single-family homes or strip malls, might not require such large ventilation cuts because their structures and fire behavior tend to be less complex, often allowing for more straightforward ventilation strategies.
