Anchor
A secure point of attachment for lifeline or lanyard.
Anchorage
A secure means of attachment to check if the personal fall arrest system is connected.
Attachment Point
A loop or "D" ring connected (integrally) to the body support that provides a means for attachment of other components of the fall protection system.
Body Harness
Means straps, which may be secured about the worker in a manner that will distribute the fall arrest forces over at least the thighs, pelvis, waist, chest and shoulders with means for attaching it to other components of a personal fall arrest system.
Carabiner
A link with a gate that is normally closed or that automatically closes, and is used to connect components of a personal fall protection system.
Connector
A device which is used to couple (connect) parts of the personal fall arrest system and positioning device systems. It may be an independent component of the system, such as a carabiner, or it may be an integral component of part of the system (such as a buckle or D-ring sewn into a body belt or body harness, or a snap-hook spliced or sewn to a lanyard or self-retracting lanyard).
D Ring
A form of attachment point on body belts and fully body harnesses meant for attachment of other components of a fall protection and positioning system.
Fall Arrest System
A system that will stop a worker's fall before the worker hits the surface below.
Fall Prevention System
Those systems and techniques that eliminate the possibility of a fall.
Fall Protection System
Any of the following when used to protect a worker from a fall or minimize the risk from falling: Guardrails, Safety belt or a full body harness with a lanyard and/or lifeline and an anchor, and their related equipment, Safety net, Control zone, Safety monitor with a control zone, and other acceptable procedures.
Fall Restraint System
A work positioning system to prevent a worker from falling from a work position, or a travel restriction system such as guardrails or a personal fall protection system to prevent a worker from traveling to an edge from which the worker could fall.
Full Body Harness
A body support device consisting of connected straps designed to distribute a fall arresting force over at least the thigh, shoulders and pelvis, with provision for attaching a lanyard, lifeline or other components.
Horizontal Lifeline System
A system composed of a synthetic or wire rope installed horizontally between two anchors, to which a worker attaches a personal fall protection system.
Lanyard
A flexible line of webbing, synthetic rope or wire rope that is used to secure a safety belt or full body harness to a lifeline or anchor.
Lifeline
A synthetic or wire rope, rigged from one or more anchors, to which a worker’s lanyard or other part of a personal fall protection system is attached.
Personal Fall Arrest System
A system used to arrest an employee in a fall from a working level. It consists of an anchorage, connectors, a body belt or body harness and may include a lanyard, deceleration device, lifeline or suitable combinations of these. As of January 1, 1998, the use of a body belt for fall arrest is prohibited.
Rope Grab
A deceleration device which travels on a lifeline and automatically, by friction, engages the lifeline and locks so as to arrest the fall of an employee. A rope grab usually employs the principle of inertial locking, cam/level locking or both (also referred to as a fall arrester).
Self-Retracting Lifeline/Lanyard
A deceleration device containing a drum-wound line, which can be slowly extracted from, or retracted onto, the drum under slight tension during normal worker movement, and which, after onset of a fall, automatically locks the drum and arrests the fall.
Shock Absorber
A device intended to to limit the deceleration forces exerted on a worker during fall arrest.
Snap Hooks
A connector comprised of a hook-shaped member with a normally closed keeper, or similar arrangement, which may be opened to permit the hook to receive an object and, when released, automatically closes to retain the object.
