A lanyard attached to a full body harness should protect the wearer from a fall no greater than how many feet?

The correct answer emphasizes that a lanyard attached to a full body harness is designed to limit the fall distance to no more than 6 feet. This is crucial for ensuring the safety of individuals working at heights, as a 6-foot maximum fall distance helps to reduce the risk of serious injury upon impact.

When considering fall protection systems, it is essential to account for various factors such as the height of the worker, potential free fall distance, and the amount of stretch in the lanyard or harness. By limiting the fall distance to 6 feet, the system can more effectively manage the impact forces that the wearer would experience, thus promoting a safer working environment.

The other options suggest greater fall distances, which would increase the likelihood of injury due to higher impact forces, not aligning with safety regulations and best practices in fall protection. Additionally, fall protection standards, such as those set by OSHA, often recommend that fall arrest systems maintain a limited fall distance to ensure that workers have a safety margin below their working height.
