5.5 Swing Fall: A swing fall occurs when the worker moves laterally out from under the anchorage and creates an expanded work zone
condition, see Figure 7. If a fall event occurs, the worker would swing back toward the anchorage. The swinging action generates
considerable force, and if the worker strikes an obstruction or makes contact with the lower level or the ground, this force could cause
severe injury or death.
Overhead Anchorage and Swing Fall: For each foot the user moves laterally in any direction away from the anchorage, the work zone
expands and swing fall forces increase. This increased force requires additional MRFC distance. See Chart 1 below for instructions
on calculating additional fall clearance distance caused by expanded work zone swing fall conditions.
Chart 1 - Additional Fall Clearance Due To Swing Fall for Overhead Anchorage, Non-Leading Edge
Dorsal
D-Ring
1 foot increments along the X-Axis represent the
distance the user is working away from the SRD Anchorage
Example:
With leg-end snap hook connected to the Dorsal D-ring on FBH, User installs a 6' SRD unit 3' overhead (up the Y axis) and 3'
laterally (along the X axis). This intersection shows 1' of additional Fall Clearance needed caused by Swing Fall. This
additional 1' must be added to the MRFC for Overhead Use shown in Figure 6.
