4.0 Using a Full-Body Har-
ness
4.1 Use of Attachment Ele-
ments (D-Rings/Web Loops)
[See Table 2]
4.1.1 Dorsal Attachment
Element - Back D-Ring/Web Loop
See Fig. 7a, 7b & 7c in Appendix A.
The dorsal attachment element or back D-
ring/web loop shall be used as the primary
fall arrest attachment, unless the application
allows for the use of an alternate attachment.
The dorsal attachment may also be used for
travel restraint or rescue.
When supported by the dorsal attachment dur-
ing a fall, the design of the full-body harness
shall direct load through the shoulder straps,
supporting the user, and through the thighs.
Supporting the user, post fall, by the dorsal at-
tachment will result in an upright body position
with a slight lean to the front with some slight
pressure to the lower chest. Considerations
should be made when choosing a sliding ver-
sus fixed dorsal attachment element. Sliding
dorsal attachments are generally easier to ad-
just to different user sizes, and a allow a more
vertical rest position post fall, but can increase
full-body harness stretch.

CAUTION: Due to the nature of soft loop
connections, it is recommended that only
soft loops and carabiners be used to con-
nect to soft loop attachments. Connecting
snap hooks to soft loops is not a preferred
connection. However, if a snap hook is
used to connect to a soft loop, the snap
hook must be ANSI compliant with a gate
strength of at least 3,600 lbs. (16 kN). (Cur-
rent CSA standards do not allow the use of
snap hooks with soft loops.)
4.1.2 Sternal Attachment Element
- Chest Area Front D-Ring
See Fig. 8a & 8b in Appendix A.
The sternal attachment may be used as
an alternative fall arrest attachment in
applications where the dorsal attachment is
determined to be inappropriate by a competent
person and where there is no chance to fall in
a direction other than feet first. Free fall shall
be limited to 2 ft. (0.6m). Accepted practical
uses for a sternal attachment include, but are
not limited to, ladder climbing with a guided
type fall arrester, ladder climbing with an
overhead self-retracting lifeline for fall arrest,
work positioning, and rope access. The
sternal attachment may also be used for travel
restraint or rescue.
