When using lanyards with a safety harness, the lanyard should limit the free fall to no more than how many feet?

The correct choice is based on safety guidelines that aim to minimize the risk of injury during a fall. When using lanyards with a safety harness, the lanyard should limit the free fall to no more than 6 feet. This limit is established to reduce the impact force on the body and to ensure that the fall is arrested safely before the individual can collide with the ground or any lower structure.

Limiting the free fall to 6 feet also accounts for the stretch of the lanyard and the safety harness, which can absorb some of the energy and further minimize the risk of injury. It is important to adhere to these guidelines to ensure that personal fall arrest systems function effectively and safely during work at heights.
