See figure 2.1 on the next page for a graphic illustration of Clear-Fall Distance and the method for
calculating. It is also necessary to consider the fall path when determining the Clear-Fall
limitations in your application. Ensure the fall path is clear of obstructions, protrusions, equipment
or materials that may be a hazard in the event of a fall. Pay special attention to those items
which may present an impalement hazard. Obstructions in the fall path may be just as hazardous
as the fall itself, and your PFAS may not be able to protect you from these hazards. Failure to
clear the fall path may result in serious injury or death. Rig your PFAS with extreme caution, and
be aware of all of the factors that may come into play in the event of a fall.

2.10: Swing-Fall
Swing-Fall is the phenomenon that occurs when the user falls from a location that is not
directly adjacent to, or directly below the anchorage connector. This is also referred to as the
“pendulum effect”, and can result in a situation where the user is not only falling vertically, but is
also swinging on the horizontal as well. This can bring additional hazards into play, as you may
swing into an obstruction or structural element, causing serious injuries (see figure 2.2). A
significant Swing-Fall may also require increased Clear-Fall distance. As a rule of thumb, you
