Horizontal Lifeline –

A component of a horizontal lifeline subsystem, consisting of a flexible line with connectors or other coupling means at both

ends for securing it horizontally between two anchorages or anchorage connectors.

Horizontal Lifeline Subsystem –

An assembly, including the necessary connectors, comprised of a horizontal lifeline component and, optionally, of:

a) An energy absorbing component or, b) A lifeline tensioner component, or both. This subsystem is normally attached at each end to an anchorage

or anchorage connector. The end anchorages have the same elevation.

Lanyard -

A component consisting of a flexible rope, wire rope or strap, which typically has a connector at each end for connecting to the body

support and to a fall arrester, energy absorber, anchorage connector or anchorage.

Lanyard Connecting Subsystem -

An assembly, including the necessary connectors, comprised of a lanyard only, or a lanyard and energy absorber.

Personal Fall Arrest System (PFAS) -

An assembly of components and subsystems used to arrest a person in a free fall.

Positioning -

The act of supporting the body with a positioning system for the purpose of working with hands free.

Positioning Lanyard -

A lanyard used to transfer forces from a body support to an anchorage or anchorage connector in a positioning system.

Qualified Person -

A person with a recognized degree or professional certificate and with extensive knowledge, training and experience in the fall

protection and rescue field who is capable of designing, analyzing, evaluating and specifying fall protection and rescue systems.

Self-Retracting Device (SRD) -

A device that contains a drum wound line that automatically locks at the onset of a fall to arrest the user, but that

pays out from and automatically retracts onto the drum during normal movement of the person to whom the line is attached.

Snaphook -

A connector comprised of a hook-shaped body with a normally closed gate or similar arrangement that may be opened to permit the

hook to receive an object and, when released, automatically closes to retain the object.

Swing Fall -

A pendulum-like motion that occurs during and/or after a vertical fall. A swing fall results when an authorized person begins a fall from a

position that is located horizontally away from a fixed anchorage.
