Personal Fall Arrest Systems
Fall arrest is of two major types: general fall arrest, such as nets; and personal fall arrest, such as lifelines. The most common manifestation of fall arrest in the workplace is the Personal Fall Arrest System, or PFAS ("lifeline").
Such a system must include 4 elements referred to as ABCDs of Fall Arrest:
- A - Anchorage - a fixed structure or structural adaptation, often including an anchorage connector, to which the other components of the PFAS are rigged.
- B - Body Wear - a full body harness worn by the worker.
- C - Connector - a subsystem component connecting the harness to the anchorage - such as a lanyard.
- D - Deceleration Device - a subsystem component designed to dissipate the forces associated with a fall arrest event.
Each of these elements is critical to the effectiveness of a personal fall arrest system. There are many different combinations of products that are commonly used to assemble a personal fall arrest system, and each must meet strict standards. The specific environment or application generally dictates the combination or combinations that are most appropriate.

Famous quotes containing the words personal, fall, arrest and/or systems:
“The ingrained idea that, because there is no king and they despise titles, the Americans are a free people is pathetically untrue.... There is a perpetual interference with personal liberty over there that would not be tolerated in England for a week.”
—Margot Asquith (1864–1945)
“Lay the proud usurpers low!
Tyrants fall in every foe!
Liberty’s in every blow!
Let us do, or die!”
—Robert Burns (1759–1796)
“The aim of every artist is to arrest motion, which is life, by artificial means and hold it fixed so that a hundred years later, when a stranger looks at it, it moves again since it is life. Since man is mortal, the only immortality possible for him is to leave something behind him that is immortal since it will always move. This is the artist’s way of scribbling “Kilroy was here” on the wall of the final and irrevocable oblivion through which he must someday pass.”
—William Faulkner (1897–1962)
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
