Wearing A Full-Body Harness - Honeywell MILLER AIRCORE Manual De Instrucciones

Limits of Use
Fall arrest connecting devices shall be attached
to the dorsal attachment element (back D-ring)
of the full-body harness unless the application
allows for the use of an alternate attachment.
(Refer to 5.1.)
Anchorage Requirements
Anchorage must be capable of supporting
5,000 lbs (22.2 kN) per worker or meet OSHA
1926.502 requirements for a safety factor of two.
ANSI anchorage requirements are as follows:
• For fall arrest systems, anchorages must
withstand a static load of 5,000 lbs (22.2 kN)
for non-certified anchorages or two times
the maximum arresting force for certified
anchorages.
• For positioning systems, anchorages must
withstand a static load of 3,000 lbs (13.3 kN)
for non-certified anchorages or two times the
foreseeable force for certified anchorages.
• For travel
withstand a static load of 1,000 lbs (4.5 kN)
for non-certified anchorages or two times the
foreseeable force for certified anchorages.
• When more than one personal fall arrest
system is attached to an anchorage, the
above anchorage strengths must be multiplied
by the number of personal fall arrest systems
attached to the anchorage.

3.0 Wearing a Full-Body
Harness
3.1 Proper Harness Fit
Correct fit of a full-body harness is essential to
proper performance. Users must be trained to
select the size and maintain the fit of their full-
body harness. Users must follow these instruc-
tions for proper fit and sizing, paying particular
attention to ensure that buckles are connected
and aligned correctly, leg straps and shoulder
straps are kept snug at all times, chest straps are
located in the middle chest area, and leg straps
are positioned and snug to avoid contact with
the genitalia should a fall occur. It is extremely
important to maintain a proper fitting harness
through the entire duration of a work shift

3.2 Donning a Harness
1. Hold harness by back D-ring. Shake har-
ness to allow all straps to fall in place.
2. If chest, waist and/or leg straps are con-
nected, release straps by unbuckling.
3. Slip straps over shoulders so D-ring is located
in middle of back between shoulder blades.
4. Pull leg strap between legs and connect to
corresponding end. Repeat with second leg
strap. Tighten leg straps so that they are
snug, but not so snug as to obstruct normal
blood circulation in the legs.
Connect waist strap/belt, if present. Waist
strap/belt should be snug but not binding.
5. Connect chest strap and position in mid-
chest area 6" (152mm) to 8" (203mm) be-
low the trachea but not below the sternum.
If adjustable, tighten chest strap to keep
must
shoulder straps taut.
Note: If the chest strap is positioned too
high, it may move upward during a fall ar-
rest causing the user to risk strangulation. If
the chest strap is positioned too low, or not
connected at all, the user will be at risk of
falling out of the harness during a fall.
6. Tighten shoulder straps until snug.
7. After all webbing straps have been buckled,
readjust harness fit as needed so that harness
is snug but allows full range of movement. Se-
cure excess strap in elastic loop keepers.
8. Verify correct harness fit using the following
checklist:

All buckles are properly connected.

Webbing straps are not twisted and are
snug with excess webbing secured in elastic
loop keepers.

Back D-ring is located in middle of back be-
tween shoulder blades.

Chest strap is positioned in mid-chest area
as specified.
Helpful Hint: When not in use, Honeywell
recommends hanging the harness by its back
D-ring to help it keep its shape and provide the
worker with a starting point when next donning
the harness.
