Which method does NOT minimize stress on slings when lifting?

The correct answer is the option that highlights the use of a low sling angle. A low sling angle means that the slings are oriented almost horizontally when lifting a load. This positioning increases the amount of stress placed on the slings due to the load's weight acting downward at a larger angle. Slings can also experience greater forces and potential slippage under these conditions, which could lead to failure or unsafe lifting scenarios.

In contrast, using a high sling angle distributes the load more evenly across the sling, minimizing stress. Employing multiple slings also helps to distribute the load, reducing the strain on any single sling. Additionally, a choker hitch provides a secure grip and increases friction, aiding in load stability while also minimizing stress on the slings. Each of these methods contributes to a safer lifting environment by managing the forces exerted on the slings.
