Additional Considerations

Swing Fall The ANSI/ASSE Z359.0-2012 standard says, “swing fall is 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.” Swing falls are typically associated with the use of a self-retracting lanyard, primarily because an SRL can be installed at a height greater than that of a shock absorbing lanyard. If cable is paid out of the de- vice as a result of the user moving away from the device horizontally, a fall (and the subsequent locking of the SRL) will cause the user to ‘swing’ like a pendulum back towards center.

Minimize the possibility of a swing fall by working as directly below the anchorage point as possible.
