A safety harness is worn by those who work at heights to reduce their risk of injury if they fall. Wearer's body spreads out the force as soon as the fall is arrested. When used, the harness is connected to the upper thigh, shoulder, and torso. An upper back loop or D-ring can be used to attach a self-retracting lanyard or shock-absorbing lanyard. D-rings at the top of the harness reduce strain on the wearer and help prevent falls. Workers can climb ladders, wear safety harnesses, and move into confined spaces with the help of D-rings.
