At what height should a y-lanyard connection to anchorage occur when attached to a back d-ring?

The appropriate height for a y-lanyard connection to anchorage when attached to a back d-ring is at shoulder level or above. This positioning is crucial for ensuring the safety and effectiveness of fall protection systems.

When the lanyard is anchored at shoulder level or higher, it helps to maintain the worker's center of gravity and reduces the risk of inversion during a fall. This means that in the event of a fall, the worker is more likely to remain in an upright position rather than flipping upside down, which can lead to serious injuries. Additionally, this height ensures that the worker does not exceed the maximum allowable fall distance, thereby potentially avoiding obstacles or hazards below.

Placing the connection at waist level, head level, or at any random height could undermine the fall protection system's effectiveness, leading to increased risks during operations.
