When making louver cuts, what is used as a fulcrum to make the louvered openings?

When making louver cuts, roof supports serve as the fulcrum. This technique involves leveraging the structure of the roof to assist in the removal of sections of roofing material, creating openings that facilitate ventilation. Roof supports provide the necessary stability and leverage required to ensure that the cuts are made effectively while maintaining control of the operation.

The use of roof supports as a fulcrum is important for safety and efficiency, as it allows firefighters to manipulate the material being cut without compromising the integrity of the overall structure more than necessary. It also aids in directing the airflow during a fire, which can help in reducing heat and smoke buildup inside a building.

Other tools mentioned, such as a pry bar or a pike pole, are utilized in various aspects of firefighting operations, but they do not serve as the fulcrum for louver cuts. While decking is part of the roof structure, it does not act as the pivot point required for creating louvered openings. Therefore, the role of roof supports is crucial in this specific technique, making it the correct choice.
