Lanyards are used to reduce impact of a fall and come with such features as shock absorbing, single or twin leg, fall restraint, and self-retracting. Shock absorbing lanyards are used when a free-fall distance exceeds two feet. Single and twin leg lanyards are similar in purpose to a shock absorbing lanyard but are for the construction industry and aerial lifts, respectively. Often with a twin lanyard, the second strap, or backup strap, is used for added protection. Single leg lanyards can be adjustable in length, from four to six feet in length.
Fall restraint lanyards are used when the fall distance is two feet or less. They are for travel restriction and stabilization of a worker at an elevation. Self-retracting lanyards, or lifelines, are used in climbing instances to allow for freedom of movement but to limit free-fall. A body belt can be used with a lanyard and harness but is not used for reducing the impact of a fall. A body belt will maintain a workers position but is only used for positioning.
