product instructions and the applicable standards pertaining
to the fall-arrest system are applied. - In particular, ensure that
no safety function of any component is affected by the safety
function of another component and that they do not interfere
with each other.
- Before every use of a fall-arrest system, the empty space
(clearance) required under the user must be verified so that, in
case of a fall, there is no collision with the ground, or with a fixed
or moving obstacle that is within the fall trajectory.
- Via a visual inspection, verify that the equipment is in good
condition and that there are no faults: condition of the straps,
seams, adjustment buckles, rings and fall indicators (
#7
). Ensure
that there is no wear, cuts, fraying, chafing, deformation, traces
of rust or discoloration and ensure that the markings are
readable (identification and/or date of validity). Ensure that the
buckles are clean and that they function properly.
USE :
- During use, regularly check the fastening and adjustment parts
of the harness and the integrated belt. These components must
be protected from any environmental stress: mechanical stress
(impacts, sharp edges, etc.), chemical stress (projection of acids,
bases, solvents, etc.), electrical stress (short-circuit, electric arcs,
etc.) or thermal stress (hot surfaces, blowtorches, etc.).
- The fall-arrest system must be connected to the dorsal D-ring
or to the sternum ring. These points are marked with the letter
A (single hooking).
- The use of the harness with a fall-arrest subsystem must be
compatible with the instructions for use of each component
of the system and with the standards: EN353-1 / EN353-
2 / EN 355 / EN360 / EN 362. For mobile fall-arrest systems
including a rigid (EN353-1) or flexible (EN353-2) belay support,
it is recommended to connect the harness using the sternum
anchor points. For energy absorbers (EN355) or self-retracting
fall-arrest systems (EN360), connect the harness to the dorsal
anchor point.
- The anchor point on the structure used to fix the fall-arrest
system must be slightly above the user, and must comply with
the minimum resistance requirements specified in the EN
795:2012 standard (R ≥ 1200 DaN). Try not to distance yourself
too much from this anchor point in order to limit the impact of
a possible pendulum fall.
- When using a lanyard for work positioning and restraint, its
anchor point must be located at the waist or above. This lanyard
must be kept tight. The two side hooking dice must always be
used together when connecting with this lanyard. Please note
that the connections are made via connectors in accordance
with EN 362.
- The tool-holder rings must not be used as anchor points or
work positioning points under any circumstances.
- After a fall or when the drop indicator is showing (
#7
)
the harness and its belt if integrated (ref NUS55C) must be
discarded.
- The use of this harness, possibly with its integrated belt for

reference NUS55C, is approved for a person weighing less than
or equal to 140Kg (The weight includes the user, his tools and
his equipment). Attention, the associated shutdown systems
must meet the normative requirements to stop a fall with a
mass of at least 140kg.
- The use of the belt (hanging on to the work holding die)
fitted with connectors with screw gate locking is accepted only
if the user does not have to lock or open the connector too
frequently that is to say several times on the same working day.
If this is the case, it will be better to use a connector with an
automatic locking.
- A connector must never have a load on its clasp.
GENERAL CONDITIONS OF USE OF THE
HARNESSES AND WORK RESTRAINT BELTS :
- A periodic inspection carried out by a competent inspector is
necessary to ensure the safety of the user, which is connected
to the maintenance of the effectiveness and resistance of the
equipment. A mandatory annual inspection will check the
condition of the equipment and it can only continue to be used
on obtaining a written agreement.
- Do not expose these products to temperatures less than -30°C
or more than +50°C.
- This equipment must not be used in any way contrary to these
specifications and under no circumstances should its limits be
exceeded.
- Storage: the product must be stored in a dry and well-
ventilated area, sheltered from any direct or indirect source of
heat and from ultra-violet rays. Drying wet equipment must be
performed in the same conditions.
- Cleaning and disinfection: exclusively with water and a neutral
soap.
- Packaging: use rot-proof and watertight protective packaging.
- Transport: packaged and sheltered from impacts or pressure
caused by the environment.
- The product must not be modified or repaired.
- Service life: Fall-protection PPE are designed to last for
several years in normal conditions of use and preservation.
The service life depends on the use. Certain environments
that are particularly aggressive, marine, siliceous or chemical
can reduce the service life of PPE. In these cases, special care
must be taken regarding protection and the inspections before
use. The mandatory annual inspection will validate the correct
functioning of the mechanism and it can only continue to be
used on obtaining a written agreement from the manufacturer
or its representative.
As concerns what has been mentioned above, the rough
estimate of the service life of the products, as recommended
by the marketing authority, is 10 (ten) years.
- Ensure that the identification sheet and the maintenance
monitoring table is kept up to date from the time of the
commissioning and during each inspection.
