Expanded Lateral Work Zone with
Leading Edge Condition
Swing Fall with 1.5 m (5 ft) Setback:
A swing fall condition is created when the user travels laterally from directly in front of or below the
anchorage, as shown in Figure 7. For each foot of work zone expansion, the risk of severe injury or death from a swing fall increases.
This increased risk requires additional MRFC distance, up to a maximum of 1.2 m (4 ft) of added clearance.
If the user exceeds maximum lateral travel, the swing force of a fall event would cause the lifeline to swing and abrade on the edge, with
increased risk of damage to or otherwise compromising the lifeline, resulting in serious injury or death to the user. Limit potential swing
fall abrasion risk by limiting lateral travel.
See Chart 2 for instructions on how to determine a safe lateral travel distance.
