X-Axis: Lateral Work Zone (m)
Using Chart 2 to Find Additional Fall Clearance: Leading Edge Conditions
0.6 m (2 ft) increments along the X-Axis represent the
distance the user is working away from the SRD
At no time shall the expanded Work Zone exceed 4.9 m (16 ft), (2.4 m (8 ft) on each side of center)
To find the additional Fall Clearance needed to compensate for potential Swing Fall, note the starting location on
Chart 2 titled Dorsal D-Ring
Example:
The starting point shown is where the SRD is anchored at Foot Level (1.5 m (5 ft) below the Dorsal D-Ring) and has
1.5m (5 ft) of setback distance from the Leading Edge. From here, the user may expand the lateral work zone up to
2.4 m (8 ft) along the X-Axis and still remain inside the allowable and cautionary areas. The expanded work zone
indicates that 1.2 m (4 ft) of additional fall clearance should be added to the Sub-Total calculation in Figure 6.
Should the user need to expand the work zone to 3.7 m (12 ft), the SRD must be anchored 4.6 m (15 ft) above the
Dorsal D-Ring to remain in the allowed and cautionary areas. This change also indicates 1.2 m (4 ft) of additional fall
clearance to be added to Figure 6.
If the user cannot anchor the SRD above the Dorsal D-Ring but still must expand the work zone, the SRD will need to
be anchored with more than 1.5 m (5 ft) of setback distance from the leading edge.
