FALL CLEARANCE CHARTS (MAXIMUM VALUES)
Find your Required Fall Clearance (FC) by using the following charts. These charts give the most fall clearance needed for your
lanyard within a specified anchorage configuration. Charts are separated by the type of lanyard you are using (see "Lanyard Style"
within Figures 1 and 2). These charts give the maximum amount of fall clearance needed for each lanyard. For a more precise
requirement, please see "Calculating Clearance (Exact Values)".
;
Fall clearance is measured from the working surface for these charts. If you would like to measure fall clearance from
your anchorage point, please see the conversion option or "Calculating Clearance (Exact Values)".
Need clearance below your anchorage point?
To find the amount of clearance needed below your
anchorage point, add your Anchorage Height (AH)
to the Required Fall Clearance (FC) for your lanyard.
