EDELRID FLEX PRO Manual De Instrucciones página 34

All full body harnesses shall include keepers or other
components which serve to control the loose ends
of straps.
9. Due to the nature of soft loop connections, it is
recommended that soft loop attachments only be
used to connect with other soft loops or carabiners.
Snap hooks should not be used unless approved for
the application by the manufacturer. Sections 10-16
provide additional information concerning the loca-
tion and use of various attachments that may be
provided on this FBH.
10. Dorsal
The dorsal attachment element shall be used as the
primary fall arrest attachment, unless the application
allows the use of an alternate attachment. The dorsal
attachment may also be used for travel restraint or
rescue. When supported by the dorsal attachment
during a fall, the design of the full body harness shall
direct load through the shoulder straps supporting
the user, and around the thighs. Supporting the user,
post fall, by the dorsal attachment will result in an
upright body position with a slight lean to the front
with some slight pressure to the lower chest. Consid-
erations should be made when choosing a sliding
versus fixed dorsal attachment element. Sliding
dorsal attachments are generally easier to adjust to
different user sizes, and allow a more vertical rest
position post fall, but can increase FBH stretch.
11. Sternal
The sternal attachment may be used as an alterna-
tive 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. Ac-
cepted practical uses for a sternal attachment in-
clude, but are not limited to, ladder climbing with a
guided type fall arrestor, ladder climbing with an
overhead self-retracting lifeline for fall arrest, work
positioning, and rope access. The sternal attach-
ment may also be used for travel restraint or rescue.
When supported by the sternal attachment during a
fall, the design of the full body harness shall direct
load through the shoulder straps supporting the
user, and around the thighs. Supporting the user,
post fall, by the sternal attachment will result in
roughly a sitting or cradled body position with weight
concentrated on the thighs, buttocks and lower
back. Supporting the user during work positioning by
the sternal attachment will result in an approximate
upright body position. If the sternal attachment is
used for fall arrest, the competent person evaluating
the application should take measures to ensure that
a fall can only occur feet first. This may include lim-
iting the allowable free fall distance. It may be possi-
ble for a sternal attachment incorporated into an
adjustable style chest strap to cause the chest strap
to slide up and possibly choke the user during a fall,
extraction, suspension... The competent person
should consider full body harness models with a
fixed sternal attachment for these applications.
12. Frontal
The frontal attachment serves as a ladder climbing
connection for guided type fall arrestors where there
is no chance to fall in a direction other than feet first,
or may be used for work positioning. Supporting the
user, post fall or during work positioning, by the fron-
tal attachment will result in a sitting body position,
with the upper torso upright, with weight concentrat-
ed on the thighs and buttocks. When supported by
the frontal attachment, the design of the full body
harness shall direct load directly around the thighs
and under the buttocks by means of the sub-pelvic
strap. If the frontal attachment is used for fall arrest,
the competent person evaluating the application
should take measures to ensure that a fall can only
occur feet first. This may include limiting the allow-
able free fall distance.
