How does a positioning device protect workers from falls?

A positioning device protects workers from falls by providing support while allowing them to maintain a working position, typically at elevation. These devices, such as harnesses or lanyards, are designed to hold a worker in place, enabling them to work hands-free while being secured. This functionality is crucial because it allows workers to perform tasks at heights without the risk of falling, as they are effectively "positioned" safely in place.

While other options might touch on elements of safety, they do not accurately describe how positioning devices function. For instance, automating the fall protection process is not the primary role of a positioning device, nor does it ensure level ground or cushion a fall. Its main purpose is to support the worker in an elevated position securely, thereby preventing falls from happening in the first place.
