Attacking a door at its exposed hinges can also be done in a brief period if the tool operator uses the collision beam(s) to assist in exposing the hinges or forcing the door.
If a side collision has bowed the door inward toward those trapped inside, the collision beam also bends or twists inward. The “vertical crush” method of forcing the door is well designed to move the top of the door and then the interior panel of the door down and out in a smooth, rolling action.
Rescue crews assigned to size up, set up and open up jammed doors must assess the location and design of the collision beam(s) inside the door. Look for signs of the beam’s location as you assess crash damage to the door. Many times, you will see the skin of the door form fit to the contour of the collision beam. Knowledge of how to work with this strong point of the door will allow crews to attain the recommended benchmark of less than 60 seconds to open any jammed door.
