3.0 SWING FALLS
An anchorage point located in a position that is not directly over the user’s fall location results in a Swing Fall (See Figure 8).
Swing falls may result in
the user striking an object with enough force to cause serious injury. Greater clearance is needed to ensure safety during a swing fall as vertical fall
distance will be greater than a fall originating directly below the anchorage point. For help determining additional required fall clearance due to Swing
Fall, (See Table 9).
