At what degree should pickets be set and facing from the load?

The principle behind setting pickets at a specific angle is to ensure optimal stability and load distribution during rescue operations. The correct choice involves setting them at a 15 degree angle, directed away from the load. This angle is critical because it helps to create a more effective tension on the anchor system, reducing the risk of failure. By angling the pickets away from the load, the force exerted is better distributed, which enhances stability and minimizes the chances of the picket being pulled out of the ground.

Moreover, other angles either do not provide enough stability or may not optimize the load distribution effectively. For example, an angle that is too steep, such as 30 degrees or 45 degrees, could increase the risk of the picket being dislodged under tension. On the other hand, a 10 degree angle directed towards the load may not sufficiently counteract the forces exerted during the rescue, potentially compromising the setup. Thus, the 15 degree angle away from the load strikes the ideal balance for a secure and reliable rescue operation.
