Elevation Safety In order to protect a worker from falling from a height, lanyards are straps or ropes that are used to secure someone to a permanent anchor point. Usually composed of strong materials like nylon or polyester, they are a part of personal fall protection systems and are meant to withstand the pressures of a fall. To protect personnel when they are working at heights in a range of sectors, including construction, electrical work, and maintenance, lanyards can be employed.
