1.0 APPLICATION
1.1 PURPOSE: The Sayine Synthetic Rope Horizontal Lifeline System
is designed for use as an anchoring means for one or two persons.
Use the Sayine Horizontal Lifeline System where horizontal
mobility and fall protection are required.
1.2 LIMITATIONS: The following limits apply to the installation and
use of the Sayine Synthetic Rope Horizontal Lifeline System.
Other limitations may apply:
IMPORTANT: The employer must ensure that each horizontal lifeline is
designed, installed, and used under the supervision of a qualied person;
and is part of a complete personal fall arrest system that maintains a
safety factor of at least two. Reference OSHA 1010.140 (c) (11). See
also OSHA 1926.502 (d)(8).
QUALIFIED PERSON: Qualied describes a person who, by possession
of a recognized degree, certicate, or professional standing, or who
by extensive knowledge, training, and experience has successfully
demonstrated the ability to solve or resolve problems relating to the
subject matter, the work, or the project. Reference OSHA 1910.140 (b).
See also OSHA 1926.32 (m).
A. HORIZONTAL LIFELINE SPAN: The maximum span distance
is 100 feet. The span length must be reduced when clearance
is limited. See section 3.2 for clearance information.
B. ANCHORAGES: The Sayfline horizontal lifeline must be
installed on anchorages that meet the requirements specified
in section 2.4.
C. SYSTEM CAPACITY: The maximum capacity of the Sayfline
horizontal lifeline is two persons. The maximum weight of each
person, including tools and clothing, is 310 lbs. (141kg).
D. CONNECTING SUBSYSTEM: Each person’s connecting
subsystem must limit fall arrest forces to 900 lbs. (4kN) or
less. See section 2.5.
5
E. FREE FALL: Rig and use the personal fall arrest system
such that the maximum potential free fall does not exceed
Government regulatory and subsystem manufacturer’s
requirements. See section 3.0 and subsystem manufacturer’s
Instructions for more information.
F. SWING FALLS: See Figure
2. Swing falls occur when
the anchorage point is not
directly overhead. The force
of striking an object in a
swing fall may cause serious
injury or death. Minimize
swing falls by working as
directly below the anchorage
point as possible. Do not
permit a swing fall if injury
could occur. Swing falls will
significantly increase the
clearance required when a
self retracting lifeline or other
variable length connecting
subsystem is used. If a swing
fall situation exists in your
application, contact 3M Fall
Protection before proceeding.
G. FALL CLEARANCE: There must be sufficient clearance below
the worker to arrest a fall before striking the lower level or
obstruction. See section 3.2 for required clearance information.
H. BODY SUPPORT: A full body harness must be used with the
Synthetic Rope Horizontal Lifeline System.

2.0 SYSTEM REQUIREMENTS
2.1 PERSONAL FALL ARREST SYSTEM COMPONENTS: The Sayine
horizontal lifeline must be used with 3M Fall Protection approved
components and subsystems. Non-approved components may
be incompatible, and could affect the safety and reliability of the
complete system. Personal fall arrest components used with this
system must meet all applicable OSHA and ANSI requirements. A
full body harness must be used with this system.
2.2 PERSONAL FALL ARREST SYSTEM CONNECTORS: Connectors
used to attach to the attachment O-ring on the horizontal lifeline
(hooks, carabiners, D-rings) must support at least
kN).
Connectors and attachment elements must be compatible
in size, shape, and strength. Non-compatible connectors may
unintentionally disengage (roll-out). Do not use non-locking
connectors with this system.
2.3 ANCHORAGE CONNECTORS: Connectors used to attach the
horizontal lifeline to end anchors must be compatible with the
connection point. The connection must be positive; and, with
connecting elements, capable of sustaining a
load without failure.
2.4 STRUCTURE LOAD: Structural anchorage points must be rigid,
and capable of supporting at least 5000 lbf (22.2 kN) along the axis
of the horizontal lifeline. Anchorages must also support at least 3600
lbf (16 kN) applied in all potential directions of fall arrest that are
perpendicular to the axis of the horizontal lifeline. See Figure 3.
WARNING: Anchorages must be rigid. 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.

5000 lbf (22.2 kN)
2.5 CONNECTING SUBSYSTEM: The connecting subsystem is the
portion of the personal fall arrest system that is used to connect
between the horizontal lifeline subsystem and harness fall arrest
attachment element. The connecting subsystem must limit forces
applied to the horizontal lifeline to 900 lbf (4kN) or less.

3.0 OPERATION AND USE
WARNING: Do not alter or intentionally misuse this equipment. Consult
3M Fall Protection when using this equipment in combination with
components or subsystems other than those described in this manual.
Some subsystem and component combinations may interfere with the
operation of this equipment. Use caution when using this equipment
around moving machinery, electrical hazards, chemical hazards, and
sharp edges.
WARNING: Consult your doctor if there is reason to doubt your
tness to absorb the impact from a fall arrest. Age and tness can
affect your ability to withstand fall arrest forces. Pregnant women and
minors must not use this system.
3.1 BEFORE EACH USE inspect this equipment according to section
5.0. Do not use this equipment if inspection reveals an unsafe or
defective condition. Plan your use of the fall protection system
prior to exposing workers to dangerous situations. Consider all
factors affecting your safety before using this system.
A. Read and understand all manufacturer’s instructions for each
component of the personal fall arrest system. All 3M Fall
Protection harnesses and connecting subsystems are supplied
with separate user instructions. Keep all instructions for future
reference.
B.
Review sections 1.0 and 2.0 to ensure system limitations and
other requirements have been adhered to. Review applicable
information regarding system clearance criteria, and ensure
changes have not been made to the system installation (i.e.
length) or occurred at the job site that could affect the required
fall clearance. Do not use the system if changes are required.
3.2 SYSTEM INSTALLATION: Figure 1 shows a typical Sayine
horizontal lifeline installation. 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 6 feet (1.8m).
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. The horizontal lifeline system should be positioned at a
level that will minimize free fall while allowing ease of use. The
horizontal lifeline should be positioned near the work location to
minimize swing fall hazards. The connecting subsystem length
should be kept as short as possible to reduce the potential free
fall and required clearance distance. Both anchorages must
be installed at approximately the same elevation, so that the
horizontal lifeline system is not sloped more than 5°.
Step 1. Determine the locations of the end anchorages and
evaluate their strengths in accordance with section 2.4.
Determine the span length and evaluate the required
clearance using Figures 4, 5, or 6 and Tables 1, 2 or 3.

Wrap Tie-Off Adaptor twice
around Anchorage Structure
connectors.
To ensure
the tie-off adaptor does not slide down a vertical or
sloped anchorage, the tie-off adaptor must be wrapped
twice around the structure as shown in Figure 7.
Refer to the tie-off adaptor instructions for complete
installation information. The horizontal lifeline may be
secured directly to the anchorage when the anchorage
incorporates a compatible attachment
element that
meets the requirements specied in section 2.3.
WARNING: For applications where the HLL cannot be located
overhead, contact 3M Fall Protection for application-specic clearance.
For use in accordance with CSA Z259 technical standards, the HLL may
not be installed at a height lower than 1 ft. below the user’s D-ring.
Step 3. Secure each end of the horizontal lifeline to the
anchorage connectors with the snap hook or carabiner.
Loosen and reposition the rope tensioner as required.
Step 4. Remove the slack from the horizontal lifeline by pulling
the rope through the tensioner by hand. To tension the
horizontal lifeline, use a pointed bar or a 1 1/4 in (32
mm) wrench and turn the tensioning nut clockwise until
the tensioner slips. Do not modify the rope tensioner to
achieve greater lifeline tension. See Figure 8. The nal
tension will be 300 to 450 lbs. (1.3 to 2.0 kN).
