Our partners at Brotherhood Instructors, LLC produced this video on how to make safe roof ventilation cuts – specifically “7-9-8 ventilation cuts” – in flat roofs. Here’s what they have to say about this video:
The 7-9-8 Ventilation cut provides a preset plan for conducting a cut. Far too often when members cut a roof, they “make each cut up as they go”. This cut will provide a plan-of-attack for each flat-roof that is opened. The design of this cut, and the steps that each cut is performed inherently keeps the firefighter from stepping inside the cut segments, thus increasing safety.
