ASSE Z359, the Manufacturer of this equipment may impose more
stringent restrictions on the use of the products they manufacturer,
see the Manufacturer’s instructions.
1 - GENERAL INFORMATION
1.1 -
The user’s organization shall retain the manufacturer’s
instructions and make them readily available to all users.
Users shall read and perfectly understand the information provided
by the manufacturer before using the device, shall comply with all
instructions regarding the inspection, maintenance and storage of
the equipment and make sure that the device is in perfect condition
and working properly.
Important
: this information relates to the
characteristics, services, assembly, disassembly, maintenance,
conservation, disinfection, etc. of the device. Although it does
include some suggestions on how to use the device, it cannot be
considered a true to life instruction manual (the same as an operating
and maintenance handbook for a car does not teach how to drive
it and does not replace a driving school).
Warning: rescue work,
tree climbing and works at height are activities with a high
degree of risk, which may lead to accidents and even death.
The user takes complete responsibility for the risks deriving from
these activities and from using our devices. This device can be used
only by individuals medically fit. It is essential that the users of this
type of equipment receive proper training and instruction, including
detailed procedures for the safe use of such equipment in their
work application. ANSI/ASSE Z359.2 establishes guidelines and
requirements for an employer’s managed fall protection program,
including policy statements, duties and responsibilities, training and
evaluations, minimum requirements for fall protection procedures,
eliminating and controlling fall hazards, rescue procedures, incident
investigations, and evaluating program effectiveness.
1.2 -
If the user has the slightest doubt concerning the efficiency of
the device, it shall be replaced immediately, particularly after having
used it to arrest a fall.
1.3 -
Minimum resistance of anchoring points, on both natural and
artificial elements, can be at least 12 kN. The assessment of those
made on natural elements (rocks, plants, etc.) is possible only
empirically, and can therefore be performed by a competent expert,
while those on artificial elements (metal, concrete, etc.) can be
calculated scientifically, and can therefore be performed by qualified
personnel.

8 - USE INFORMATION
8W0.050 SIERRA DUO ANSI
(fig. 1) is a full body harnesses (FBH)
meet ANSI/ASSE Z359.11:2014, fitted with two attachment points, one
dorsal (C) and one sternal (D) consisting of two attachment elements.
It is intended to be used with other components of a personal fall arrest
system that limit maximum arrest forces to 1800 pounds (8 kN) or less.
Fig. 1 – Nomenclature and main materials: (A) Shoulder straps of
polyester, (B) Sit harnesses of polyester, (C) Dorsal attachment point of
carbon steel, (D) Sternal attachment point of polyester, (E) Adjustment
buckles of carbon steel, (F) Sternal sling of polyester, (G) Loops of nylon
or polyester, (H) Slings of polyester, (I) Load indicators.
Warning: a prolonged suspension onto a harness, above all if
unconscious, may cause the suspension syndrome, also called
suspension trauma or orthostatic intolerance, that can lead to fatal
consequences!
It is a serious condition that can be controlled by post fall suspension
relief devices and prompt rescue. A conscious user may remove tension
from around the legs, freeing blood flow, which can delay the onset of
suspension intolerance.
8.1 - Wearability
First of all check the size-choosing the correct one for you (see SIZE
table), 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 (fig.5), and leg
straps are positioned and snug to avoid contact with the genitalia should
a fall occur.
To wear the harness correctly:
a) loosen the slings (H),
b) unthread the sternal sling (F) from its buckle,
c) holding the harness by the dorsal attachment point (C) spread out the
shoulder straps (A) – (fig.2),
d) slip your legs through the belt (B),
e) slip your arms into the shoulder straps (A),
f) thread the sternal sling (F) through its buckle (fig. 3),
g) adjust the harness tightening the slings (H) - (fig. 4) and check
attachment elements (dorsal and sternal) correct positioning,
h) position the loops (G) to hold the exceeding sling,
which can get
caught or cause accidental disengagement of an adjuster.
Important:
-
before using the harness, find a completely safe position and carry
out movements and suspension tests on each attachment point to
make sure the harness is of the right size, adjusted properly and
comfortable for your intended use,
-
regularly check the closure of the adjustment buckles when in use,
-
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.
8.2 – Use in a fall arrest system
For the sake of safety in case of risk of falls from a height, it is essential
to:
-
assess the risks and make sure that the whole system, where this
device is only a component, is reliable and safe,
-
prepare a rescue plan to deal with any emergencies possibly
arising while the device is being used,
-
have the means at hands to implement the rescue plan,
-
make sure that the anchoring device or the anchoring point is
always positioned as high up as possible, and that work is done
in such way as to reduce potential falls and relevant heights to
a minimum,
-
a harness is only a component of a fall arrest system, therefore
it shall be connected to other devices (i.e. shock absorber,
ropes, etc.) in order to obtain a fall arrest system,
-
an energy absorber can be used to limit maximum arrest forces
to 1800 pounds (8 kN),
-
in order to avoid all possible problems (e.g. ground, material
rubbing against the rock face, abrasions, etc..), carefully assess
the free height under the user (clearance). Examples of main
factors can be: height of a potential fall, Full Body Harness
Stretch (Hs), rope paid out, the length of any attachment element
extender, the stretch in any energy dissipaters or absorbers, the
height of the user and the “pendulum” effect.
-
Full Body Harness Stretch (Hs) is the amount the FBH
component of a personal fall arrest system will stretch and
deform during a fall (fig. 6, 7), 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.
8W0.050 SIERRA DUO ANSI Full Body Harness Stretch (Hs) is by
far less than 18 in. (457 mm).
Important:
in a system for protection against falling from heights, it
is obligatory to use a complete harness in compliance with current
regulations.
8.3 – Acceptable use for attachment elements
Warning: connect to the attachment point with soft loops
carabiner connectors only. Plain hooks cannot be used!
