Fall Arrest - Personal Fall Arrest Systems

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:

    In the weakness of one kind of authority, and in the fluctuation of all, the officers of an army will remain for some time mutinous and full of faction, until some popular general, who understands the art of conciliating the soldiery, and who possesses the true spirit of command, shall draw the eyes of all men upon himself. Armies will obey him on his personal account. There is no other way of securing military obedience in this state of things.
    Edmund Burke (1729–1797)

    Now I know that much of parenthood is watching and waiting for the chick to fall into harm’s way, watching and waiting for the cats and the cold nights. The joyous enterprise has an undercurrent of terror.
    Anna Quindlen (b. 1952)

    One does not arrest Voltaire.
    Charles De Gaulle (1890–1970)

    People stress the violence. That’s the smallest part of it. Football is brutal only from a distance. In the middle of it there’s a calm, a tranquility. The players accept pain. There’s a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, there’s a satisfaction to the game that can’t be duplicated. There’s a harmony.
    Don Delillo (b. 1926)
