FALL CLEARANCE CHARTS
Required Fall Clearance has been provided within the charts below. To determine Required Fall Clearance:
1. Select the clearance chart that matches your product type and includes a capacity fitting your combined weight.
2. Determine the Anchorage Height (A) of your subsystem. Anchorage Height is measured from the top of the working platform
to the bottom of your anchorage connection point.
3. Determine the Setback Distance (B) of your system. Setback Distance is measured from directly below your anchorage
connection point to the edge of the working platform.
4. After obtaining your Anchorage Height (A) and Setback Distance (B), use (A) and (B) within the Fall Clearance Chart to
determine your Required Fall Clearance (FC).
;
When values for (A) and (B) measured by the user do not match those listed in the table, the user should round up to the
next highest listed value. If there is no higher listed value, then the user should reduce their intended Anchorage Height or
Setback Distance to a lower value.
;
A Safety Factor of 0.45 m (1.5 ft.) and a user height of 1.8 m (6.0 ft.) were used for all values listed. Kneeling or
crouching will reduce effective user height and will require an additional 1.0 m (3.28 ft.) of Fall Clearance.
