Honeywell MILLER AIRCORE Manual De Instrucciones página 9

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. Support 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 this sternal attachment will
result in an approximate upright body position.
If the sternal attachment is used for fall arrest,
the competent person evaluating the applica-
tion 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
possible for a sternal attachment incorporated
into an adjustable style chest strap to cause
the chest strap to slide up and possibly choke
theuser during a fall, extraction, suspension,
etc. The competent person should consider
full-body harness models with a fixed sternal
attachment for these applications.
WARNING
Never use shoulder, rear-waist, hip or
suspension seat attachment elements
for fall arrest.
4.1.3 Shoulder Attachment
Elements - Shoulder D-Rings
See Fig. 9 in Appendix A.
The shoulder attachment elements shall be
used as a pair and are an acceptable at-
tachment for rescue and entry/retrieval. It is
recommended that the shoulder attachment
elements be used in conjunction with a yoke
which incorporates a spreader element to
keep the full-body harness shoulder straps
separate.
4.1.4 Rear-Waist Attachment
Element
See Fig. 10 in Appendix A.
The rear-waist attachment element shall be
used solely for travel restraint. The rear-waist
attachment shall only be subjected to minimal
loading through the waist of the user and shall
never be used to support the full weight of the
user.
WARNING
Do not use the rear-waist attachment el-
ement for any purpose other than travel
restraint.
4.1.5 Hip Attachment Elements -
Side D-Rings
See Fig. 11a & 11b in Appendix A.
The hip attachment elements shall be used as
a pair and shall be used solely for work posi-
tioning or travel restraint. Hip attachments are
often used for work positioning by arborists,
utility workers climbing poles, and construc-
tion workers tying rebar and climbing form
walls.
CAUTION: Do not use the hip attachment
elements (or any other rigid point on the
full-body harness) to store the unused end
of a fall arrest lanyard as this may cause a
tripping hazard or, in the case of multiple
leg lanyards, could cause adverse loading
to the full-body harness and the wearer
through the unused leg of the lanyard.
4.1.6 Suspension Seat
Attachment Elements
See Fig. 12 in Appendix A.
The suspension seat attachment elements
shall be used as a pair and shall be used solely
for work positioning. Suspension seat attach-
ments are often used for prolonged work ac-
tivities where the user is suspended, allowing
the user to sit on the suspension seat formed
between the two attachment elements. An ex-
ample of this use would be window washers
on large buildings.
4.1.7 Suspension Loop
Attachment Elements
See Fig. 13 in Appendix A.
The suspension loop attachment elements
shall be used as a pair and shall be used sole-
ly for work positioning.
