can be sheathed and furnished with automatic connectors with

swivel plates (#1-4) (Reference with the suffix FF). The "PRODUCT

REFERENCE" table summarises the different existing versions.

The NLDVM lifeline can only be used horizontally, with a

minimum range of 5 meters and a maximum range of 20 meters,

without an intermediate point and without any bend(#2).

In the case of a fall arrester system, it must always be used with

a fall protection system limiting stress to 600 daN in case of a fall

(mobile fall arrestor on rigid belaying support EN353-1, mobile fall

arrestor on flexible belaying support EN353-2, energy absorber

EN355, self-retracting fall arrester EN360). In case of integrated

use in a restraint system or in a work-positioning system, it must

be used as a complement to a lanyard as per EN358 or EN354.

VERIFICATIONS :

- When combining the fall arrest system with other safety

components, verify the compatibility of each of the components

and make sure to apply all recommendations from product

notices and the applicable standards relative to fall arrest

systems. Ensure in particular that the safety functions of one

of the components are not affected by the safety functions of

another component and that they do not interfere with each

other.

- Before each use of a fall arrest system, it is imperative to verify

the free fall space (clearance) required under the user, in such

a manner that in the event of a fall, there is no collision either

with the ground or with a fixed or moving obstacle that is found

within the trajectory. The clearance under the user's feet must

take into account the maximum sag of the lifeline and the

air draft required for the fall arrest equipment used (see

manual of the equipment used)(#4): Minimum clearance = y + 1

m + fall arrester minimum clearance.

- Caution, the clearance is likely to increase if the lifeline is

combined with a fall protection device with automatic return

(EN360) or a mobile fall protection device on a flexible anchorage

support (EN353-2) which have not been tested together. In

addition, the deflection caused in case of a fall must not bring the

safety line in contact with a sharp edge or any other component

capable of damaging the strap.

- Check, by visual inspection, before, during and after use, that the

equipment is in good condition and for the absence of defects. In

case of doubt about the reliability of the equipment, do not use

it before obtaining written authorization from a person who is

competent to decide on its reuse.

• Condition of the straps: no incipient fractures, no cuts, no

fraying, no wear and tear at the stitches.

• Condition of the tensioner: no oxidation or discoloration,

no wear and tear, no deformation. Verify the cleanliness of the

tensioner and its proper functioning.

• General condition: Ensure the legibility of the markings

(identification and/or validity date).

• Condition of the connectors: Non-activation of the fall

indicators, no apparent wear and tear, no traces of oxidation or

discoloration, no deformation.

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 end of the extension strap if it has one, or to two sternal

rings simultaneously. These points are identified by the letter

A (single fastening) or A/2 (these points must be connected

together).

- Use the tape slings (#1-3) to fix the ends of the mobile safety

line around a beam or a suitable structure (endurance, absence

of sharp edge or abrasive surface). The structure must be able to

resist a stress of at least 18 kN. Connect the tape slings with the

help of the connectors of the safety line that are in compliance

with the EN362 standard (#1-4). The assembly is in compliance

with the requirements of standard EN795:2012 B+C type (Hybrid).

- In the case where EN795-compliant structural anchoring

points already exist, it is possible to connect them directly to

EN362 compliant connectors (#1-4) located at the ends of the

safety line. This setup is in compliance with the requirements of

standard EN795:2012 type C.

- The anchoring points on the structure where the safety line

will be fixed must be above the user and must be positioned

in such a manner so as to minimise both the risk of falling and

the distance of the fall. The maximum authorised angle from

the horizontal is 15°. The installation of anchor points must be

done particularly carefully and by specialists in this work. It is

recommended to have the installation verified by an inspection

body or an authorised individual.

- The table of the diagram #4 shows the results that are the

outcome of regulatory drop tests. The user must take into

account the following at the time of installation and during the

use of the mobile safety line :

• Maximum dynamic deflection (y)

• Residual deflection after the fall (x)

• Measured stress at the mobile anchor point (P)

• Measured stress at the terminal anchors of the safety line (F)

- Avoid deviating too much from the lifeline's plumb line in order

to limit the scope of a possible pendulum drop.

- After a fall, the mobile lifeline should be destroyed and replaced.

- Installation and dismantling of the equipment (#5) :

• Pos 1 : Pull the strap taut by means of the strap tensioner by

the maximum force of the user i.e. F ≥ 70 daN. Before each use,

check the proper tautness of the strap - maximum deflection of

the strap = 1/200° of the load radius.

• Pos 2 : Locking of the handle of the tensioner with a pawl in

order to prevent any maladjustment during the use of the

equipment.

• Pos 3 : Unlocking of the handle of the tensioner with a pawl for

dismantling the equipment.

- Directly connect a lanyard as per EN358 or EN354 or an energy

absorber as per EN355 to the installed safety line in compliance

with the requirements of the respective user instructions. The

connectors must be compliant to the EN362 standard.

- Connect only EN360 self-retracting fall protections and EN353-2

flexible anchor type fall protection devices that have been tested

in combination with the NLDVM lifeline.

- Caution: the NLDVM mobile safety line is designed to be used

by a maximum of 2 persons simultaneously.
