FALL CLEARANCE CHARTS - LEADING EDGE DEVICES (SRD-LE)
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 Setback Distance (A) of your subsystem. Setback Distance is measured from your anchorage connection point
to the edge of the working platform.
3.
Determine the Horizontal Distance (B) of your subsystem. Horizontal Distance is measured from the point on the edge directly
opposite your anchorage connection point to the point on the edge that equals the furthest extent of your work area.
4.
After obtaining your Setback Distance (A) and Horizontal 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.
;
To determine the fullest extent of the user’s work radius, it may be necessary to repeat these steps for each leading edge
the user will be near.
