What best describes fall restraint?

Fall restraint is a safety system designed to prevent a worker from falling from an elevated position. This is achieved by using equipment such as harnesses, lanyards, and anchor points that limit the range of movement, thereby ensuring that the worker remains within a safe distance from the edge or hazard. The fundamental purpose of fall restraint systems is to keep workers safe by avoiding fall incidents altogether.

The other options do not accurately represent the concept of fall restraint. For example, ensuring a worker remains at a height refers to the ability to work at elevated levels but does not inherently include the preventive measures that fall restraint entails. Allowing free movement at heights can potentially lead to unsafe situations where a fall could occur if the boundaries established by fall restraint are not respected. Stopping a fall after it has occurred defines the role of fall arrest systems, which are different from fall restraint measures since they come into play only after a fall has happened. Thus, understanding fall restraint as a proactive safety measure is key in the context of workplace safety in telecommunications and other industries involving heights.
