What is one of the first steps in setting up the parallel plaquette technique?

One of the first steps in setting up the parallel plaquette technique involves attaching a quad-sized runner to the anchor. This step is crucial because the quad runner creates a flexible anchor point that allows for effective load distribution and management during the rescue operation. By securing the quad runner, you establish a stable anchor for the subsequent steps in the process, which are essential for safety and efficiency during the rescue.

The use of a quad runner is particularly advantageous because it can be configured to allow multiple attachments or to facilitate easier adjustments, providing versatility in various rescue scenarios. Properly securing this element sets the foundation for the rest of the setup, ensuring that the system is reliable when it comes to managing loads and transferring forces.

In contrast, tying a Munter hitch, clipping a D carabiner to the belay device, and running the tail end of the rope through a carabiner are all steps that typically follow the establishment of the anchor system. Hence, while they are important components of the overall setup, they do not represent the initial step when utilizing the parallel plaquette technique.
