Lanyards must allow a worker to move about with a maximum of security without getting in the way.
There are two principal uses for lanyards:
Restraint and work positioning lanyards are used with a work positioning harness.
They are designed to limit movement or for hands free work while in position.
Energy absorbing lanyards are part of a fall arrest system.
Energy absorbing lanyards should be used only after checking that there is adequate clearance under the user.
