Safety harnesses for confined spaces have one D-ring on the upper back and two D-rings on the shoulder straps. They are used to lower or raise workers into or out of a confined space, such as a manhole. The shoulder D-rings also provide extra connection points that may be more accessible than the back D-ring if the worker faints or falls and needs to be extracted. The back D-ring attaches to a self-retracting lifeline or shock-absorbing lanyard that connects to a secure anchor point.
