Falltech 727630LE, User Instruction Manual

Page: 29 / 43

To find the additional Fall Clearance needed to compensate for potential Swing Fall,
note the starting location on Chart 1 titled
Dorsal D-Ring
At no time shall the expanded Work Zone exceed 16’ (8’ on each side of center)
2 foot increments along the
X-Axis represent the distance the user is working
away from the SRD Anchorage.
5 foot increments up the
Y-Axis represent the SRD Anchorage height
above or below the user’s Dorsal D-Ring
Should the user need to expand the work zone to 12’, the SRD must be anchored 15’ above
the Dorsal D-ring to remain in the allowed and cautionary areas. This change also indicates
4’ of additional fall clearance to be added to
Figure 3A
Example:
The starting point shown is where the SRD is anchored at Foot Level (5’ below the Dorsal
D-ring) and has 5’ of Setback distance from the Leading Edge. From here, the user may
expand the lateral work zone up to 8’ along the X-axis and still remain inside the allowable
and cautionary areas. This expanded work zone indicates that 4’ of additional fall clearance
should be added to the Sub-total calculation in
Figure 3A
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 5’ of setback distance from the
leading edge.
