FALL CLEARANCE CHARTS
Find your Required Fall Clearance (FC) by using the following charts. To determine Required Fall Clearance for your situation:
1. Determine your Anchorage Placement (AP). Measure the distance between your vertical lifeline's anchorage point and
your lifeline subsystem.
2. Find your Required Fall Clearance (FC). Enter the value from Step 1 into the fall clearance tables to find your Required
Fall Clearance.
;
Each time your lifeline subsystem is moved to a different anchorage height, you will need to calculate Required Fall
Clearance (FC) again.
;
Required Fall Clearance (FC) values account for lifeline elongation, user height, and a Safety Factor. A user height of 6.0
ft. (1.83 m) and a Safety Factor of 1.5 ft. (0.46 m) were used for all values.

TIP: FREQUENT ADJUSTMENTS
In some work situations, it may be necessary to frequently adjust your lifeline subsystem. To avoid having to recalculate fall
clearance each time you adjust, measure Required Fall Clearance (FC) from your lowest working point.
1. Determine the lowest point your lifeline subsystem will be anchored on the vertical lifeline. This is your lowest working
point.
2. Measure Anchorage Placement (AP) from your lowest working point. Use this value to find your Required Fall Clearance.
3. Ensure your work location has enough fall clearance at all times to accommodate the Required Fall Clearance from Step 2.
Never place your lifeline subsystem below the point set in Step 1.
