3.0 INSTALLATION
;
Installation of the DBI-SALA EZ-Line Horizontal Lifeline must be supervised by a Qualified Person
must be certified by a Competent Person as meeting the criteria for a Certified Anchorage, or that it is capable of
supporting the potential forces that could be encountered during a fall.

3.1 PLANNING: Plan your fall protection system prior to installation of the EZ-Line Horizontal Lifeline. Account for all factors
that may affect your safety before, during and after a fall. Consider all requirements, limitations and specifications defined
in Section 2 and Table 1.
3.2 PREINSTALLATION CONSIDERATIONS: The EZ-Line Horizontal Lifeline System (HLL) is intended as a temporary
horizontal lifeline that retracts into a housing for easy stoarage and portability. The HLL is designed for use as an
anchoring means for one or two personal fall arrest systems (PFAS) in compliance with EN 355 (Shock Absorbing Lanyard)
or EN 360 (Self Retracting Lifeline—see list of models we recommend on the last page of this instruction) or for restraint
subsystem in compliance with EN 354. The horizontal lifeline has been tested in accordance with EN 795 Class C. The
system should be removed from the job site when no longer required.
• Both anchorages must be installed at approximately the same elevation, so that the horizontal lifeline system is not
sloped more than 15°.
• Structural anchorage points must be non-deforming and capable of supporting at least 22.2 kN (5000 lbs.) along
the axis of the horizontal lifeline. Anchorages must also support at least 16.0 kN (3,600 lbs.) applied in all potential
directions of fall arrest that are perpendicular to the axis of the horizontal lifeline. (See Figure 3)
;
Anchorages must be of a non-deforming type. Large deformations of the anchorage will affect system performance
and may increase the required fall clearance below the system, which could result in serious injury or death.
;
Both ends of the lifeline must be securely attached to appropriate anchors when in use. Never attach the end of the
lifeline to a harness to use it in the manner of a winch or SRL.
• Maximum horizontal lifeline span is 18.2 m (60 ft.). Span length must be reduced when fall clearance is limited.
• The horizontal lifeline system should be positioned at a level that minimizes free fall while allowing ease of use.
• The connecting subsystem length should be kept as short as possible to reduce the potential free fall and required
clearance distance.
• When using an energy absorbing lanyard to connect to the system, the end anchorages must be located at a height
which will limit the free fall to 1.8 m (6 ft.).
• When using a self retracting lifeline (SRL) to connect to the system, the end anchorages must be located above the
user. The SRL, when fully retracted, must be above the harness attachment level.
• Each person's connecting subsystem must limit fall arrest forces to 6.0 kN (1,350 lbs.).
• If there are two persons connected to the HLL, when a person falls while connected to the HLL, the system will deflect.
If two persons are connected to the same HLL, and one person falls, the second person may be pulled off the working
surface due to deflection. The potential for the second person falling increases as the HLL span length increases. The
use of independent HLL systems for each person or shorter span length is recommended in order to minimize the
potential of the second person falling
3.3 INSTALLATION OF THE EZ-LINE HORIZONTAL LIFELINE:
1. Step 1. (See Figure 2) Inspect that the following parts are present and in good condition: housing (B), lifeline (A),
two carabiners (D and E), impact indicator (G).
2. Determine the locations of the end anchorages (E) and evaluate their strengths in accordance with the loads specified
in Figure 3. Determine the required fall clearance by using the following calculations:
•
DBI-SALA Shock Absorbing Lanyards: Figure 8 calculates fall clearance requirements (FC) for one user (Table
4.1) and two users (Table 4.2). (Example: Two users choose to connect to the system with shock absorbing
lanyards. If the span length between end anchorages (E) is 12.2 m, use Table 4.3 to look up the letter that
corresponds to that length, which is "D." If the lanyard length (G) is 1.5 m, use Table 4.4 to look up the letter that
corresponds to that length which is "Y." Using Table 4.2 and letters "D" and "Y" locate the number where the two
letters intersect which is 6.7 m. Fall clearance is 6.7 m for two users attached to the system.)
•
DBI-SALA Self Retracting Lifeline: Figure 9 calculates fall clearance requirements (FC) for one user (Table 5.1)
and two users (Table 5.2). (Example: One user chooses to connect to the system with a self retracting lifeline. If
the span length between end anchorages (E) is 6.1 m, use Table 5.3 to look up the letter that corresponds to that
length, which is "B." To determine fall clearance (F) for one user see Table 5.1 and look at the number next to "B"
which is 2.4 m. Fall clearance is 2.4 m for one user attached to the system.)
;
Values stated in clearance tables include a 1m clearance margin.
3. (See Figure 10, 1) Press the button (J) on top of the housing unit and hold it down to pay out the lifeline (B). Pull
on the lifeline (B) until the required length is achieved. Make sure that the crank handle is in its resting position (K).
When the button (J) is released, it will spring back and the lifeline will lock in place. If the lifeline does not lock, do
not use. The unit must be returned to an authorized dealer for service.
4. (See Figure 10, 2) Refer to manufacturer's instructions provided with the anchorage connectors for installation
requirements. Install the horizontal lifeline (B) by attaching it to the anchorage connectors (E) using the carabiners
(C) provided.
6 Qualified Person:
An individual with a recognized degree or professional certificate, and extensive experience in Fall Protection. This individual must be capable
of design, analysis, evaluation, and specification in Fall Protection.
