nents of a personal fall arrest system that limit max-
imum arrest forces to 1800 pounds (8 kN) or less.
5. Suspension intolerance, also called suspension
trauma or orthostatic intolerance, is a serious condi-
tion that can be controlled with good harness design,
prompt rescue, and post fall suspension relief devic-
es. A conscious user may deploy a suspension relief
device allowing the user to remove tension from
around the legs, freeing blood flow, which can delay
the onset of suspension intolerance. An attachment
element extender is not intended to be attached di-
rectly to an anchorage or anchorage connector for
fall arrest. An energy absorber must be used to limit
maximum arrest forces to 1800 pounds (8 kN). The
length of the attachment element extender may
affect free fall distances and free fall clearance cal-
culations.
6. Full body harness (FBH) stretch, the amount the
FBH component of a personal fall arrest system will
stretch and deform during a fall, can contribute to
the overall elongation of the system in stopping a fall.
It is important to include the increase in fall distance
created by FBH stretch, as well as the FBH connector
length, the settling of the user's body in the FBH, and
all other contributing factors when calculating total
clearance required for a particular fall arrest system.
7. When not in use, unused lanyard legs that are still
attached to a full body harness D-ring should not be
attached to a work positioning element or any other
structural element on the full body harness unless
deemed acceptable by the competent person and
manufacturer of the lanyard. This is especially im-
portant when using some types of Y-style lanyards,
as some [dangerous shock] load may be transmitted
to the user through the unused lanyard leg if it is not
able to release from the harness. The lanyard parking
attachment is generally located in the sternal area to
help reduce tripping and entanglement hazards.
8. Loose ends of straps can get caught in machinery
or cause accidental disengagement of an adjuster.
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
