The sternal D-ring is designed for fall attachment when the fall distance is not greater than what measurement?

The sternal D-ring is intended for use as an attachment point for fall protection harnesses, particularly when a person might be at risk of falling from heights. The specific measurement associated with the safe use of the sternal D-ring pertains to the maximum fall distance to ensure safety. When using this attachment point, the fall distance should not exceed 2 feet. This is because the sternal attachment is positioned to help keep the worker's body in a stable and upright position and minimize the impact of a fall. Beyond this distance, there is an increased risk of injury or equipment failure, which is why the limit is set specifically at 2 feet. It helps maintain safe working conditions and conforms to safety standards that protect workers engaged in elevated tasks.
