Leading Edge
The edge of a floor, roof, or formwork for a floor or other walking or working
surface (such as the deck) which changes location as additional floor, roof,
decking, or formwork sections are placed, formed, or constructed. A leading
edge is considered to be an “unprotected side and edge” during periods when it
is not actively and continuously under construction.
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.
Low-Slope Roof
A roof having a slope less than or equal to 4 in 12 (vertical to horizontal).
Lower Levels
Those areas or surfaces to which a worker can fall. Such areas or surfaces
include, but are not limited to, ground levels, floors, platforms, ramps, runways,
excavations, pits, tanks, material, water, equipment, structures, or portions
thereof.
Passive Fall Prevention
Refers to a system that is non-dynamic, stationary, and does not move, adapt, or
change when in or out of use. Passive systems don’t require the use of personal
protective equipment or active participation from the worker. Typically, passive
systems include netting, handrails, and guardrails.
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.
Positioning System (work-positioning system)
A system of equipment and connectors that, when used with a body harness or
body belt, allows an employee to be supported on an elevated vertical surface,
such as a wall or window sill, and work with both hands free. Positioning systems
also are called “positioning system devices” and “work-positioning equipment”.
Qualified

standing, or who by extensive knowledge, training, and experience has
successfully demonstrated the ability to solve or resolve problems relating to
the subject matter, the work, or the project.
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
