3.13 CONVERSION TO A MULTIPLE-SPAN SYSTEM: To reduce the amount of fall clearance required, the EZ-Line HLL
System may be converted to a multiple-span system. The below guidelines must be followed:
Intermediate anchorages and end anchorages must meet the loading requirements specified in Table 1.
A Rolled Metal Energy Absorber must be added to the end of the system opposite the winch assembly.
The swaged connections of the EZ-Line HLL System should not be removed or disassembled to permit passage through
intermediate brackets or secured anchorage connectors. All brackets and anchorage connectors must either have large
enough openings to receive the assembled system or be capable of mid-line attachment without needing to thread the
cable end.
;
Carabiners may be attached directly to the HLL System when securing to intermediate anchors. See Section 4.3
for more information.
Connectors and brackets used to create intermediate anchorages must allow free passage of the horizontal lifeline
such that it is not held tightly or restricted from sliding along the axis of the HLL.
Connectors and brackets used to create intermediate anchorages must not contain sharp or abrasive edges which
could come in contact with the horizontal lifeline.
100-percent tie-off is required when using the HLL system. If intermediate brackets and connectors do not permit the
connecting subsystem to bypass, it will be necessary to use twin lanyards or twin SRDs to maintain connection to the
system when moving between spans.
;
The maximum capacity of your system will vary depending on its application. See Table 1 for capacity requirements.
;
In multiple-span HLL systems designed under ANSI Z359.6 or CSA Z259.16 to permit multiple users in
multiple spans, it is the responsibility of the Qualified Person (and not of 3M) to evaluate and document the design
considerations and details which ensure a single event or circumstance will not cause multiple users in multiple spans to
fall within a very short period of time.

USE
4.1
BEFORE EACH USE: Verify that your work area and Fall Protection system meet all criteria defined in these instructions.
Verify that a formal Rescue Plan is in place. Inspect the product per the 'User' inspection points defined on the "Inspection
and Maintenance Log". If inspection reveals an unsafe or defective condition, or if there is any doubt about its condition
for safe use, remove the product from service immediately. Clearly tag the product "DO NOT USE". See Section 5 for more
information.
4.2
SYSTEM APPLICATIONS: Figure 14 illustrates the system applications for which this HLL System may be used. The
HLL System may be used for either Restraint or Fall Arrest applications. Figure 14.1 illustrates application as a Restraint
system. Figure 14.2 illustrates application as a Fall Arrest system. Placement of the HLL System (A) is indicated, but the
system should always be installed per the requirements of these instructions and the specifics of your work location.
Whenever possible, work at or below the level of the HLL System. To avoid swing fall hazards, do not work too far from
either side of the HLL System.
4.3
CONNECTING TO THE HLL SYSTEM: Appropriate Fall Protection equipment must be worn when installing or connecting
to the HLL System. The user's connecting subsystem should be secured either to one of the O-ring attachment elements
on the HLL System or directly to the HLL System itself.
;
All connectors used with the HLL System must meet Section 2.7 and Section 2.8 requirements. Additionally, all
connectors that secure directly to the HLL System must have a gate strength of 3,600 lbf (16 kN) or greater.
4.4
USE WITH TWO PERSONS: When one person falls while connected to the HLL System, the system will deflect. If two
persons are connected to the same HLL System and one person falls, the second person may be pulled off the working
surface due to deflection. The risk of the second person falling increases as the span length of the HLL System increases.
The use of independent HLL Systems for each person, or a shorter span length, is recommended to minimize risk.
;
In multiple-span HLL systems designed under ANSI Z359.6 or CSA Z259.16 to permit multiple users in
multiple spans, it is the responsibility of the Qualified Person (and not of 3M) to evaluate and document the design
considerations and details which ensure a single event or circumstance will not cause multiple users in multiple spans to
fall within a very short period of time.
4.5
AFTER A FALL: If the product is subjected to fall arrest or impact force, remove it from service immediately. Clearly tag
it "DO NOT USE". See Section 5 for more information.
