What is the first cut that should be made when forcing an overhead door?

When forcing an overhead door, the first cut that should be made is vertical. This approach is crucial because it allows firefighters to create a penetration point that aligns with the supports of the door, facilitating easier access to the mechanism or space behind the door. A vertical cut runs parallel to the door's hardware and can help expose the locking mechanism more effectively, allowing for further modifications if needed.

Making the cut in a vertical manner aids in minimizing material displacement, which can be important in maintaining the structural integrity of the area around the door. It also provides clearer visibility and easier handling during the forcing process, allowing firefighters to assess the situation better.

In contrast, horizontal, diagonal, and cross-cuts may not be as effective for initial penetration with overhead doors, as they can complicate the access to the necessary components or even lead to unintended door movement or complications with the door's mechanism. Such cuts might require additional effort to complete the task efficiently.
