Safety harnesses are used with self-retracting lifelines or shock-absorbing lanyards to connect a worker's body to an anchor point. These fall-protection harnesses are secured around a worker's shoulders, torso, and thighs. In the event of a fall, the harness spreads the force of the fall across the body and keeps the worker upright. Safety harnesses are often paired with accessories that add extra safety features to the harnesses or provide comfort or convenience to people wearing the harnesses. Body belts are worn around the waist. They connect to positioning and restraint lanyards to keep workers positioned properly and prevent them from falling over an edge. Body belts do not provide fall-arrest protection on their own.
