1.0 PRODUCT APPLICATION
1.1 PURPOSE: These Horizontal Lifeline (HLL) Anchorage Systems provide multiple anchorage connection points for Personal
Fall Arrest Systems (PFAS) and Personal Fall Restraint Systems (PFRS). They employ a fl exible anchor line, which deviates
from horizontal by no more than 15°. Mobile anchorage connection points ensure user connection along the entire length
of the system.
HLL Systems must only be used for Personal Fall Protection Equipment. Do not use HLL Systems as anchorage for lifting
equipment.
1.2 STANDARDS: Your HLL System conforms to the national or regional standard(s) identifi ed on the front cover and Table
1 of these instructions. If this product is resold outside of the original country of destination, the re-seller must provide
these instructions in the language of the country where the product will be used.
1.3 SUPERVISION: Use of this equipment must be supervised by a Competent Person
1.4 INSTALLATION DOCUMENTATION: After installation of the Anchorage System, "Installation Documentation" meeting
the informational requirements of EN 795:2012 Annex A (or equivalent
over to the user's designated representative. The installation Documentation should be kept at the job site for purposes of
subsequent examination of the Horizontal Lifeline System.
1.5 TRAINING: This equipment must be installed and used by persons trained in its correct application. This manual is
to be used as part of an employee training program as required by EN 365 and other applicable Fall Protection codes,
standards, or requirements. It is the responsibility of the users and installers of this equipment to ensure they are
familiar with these instructions, trained in the correct care and use of this equipment, and are aware of the operating
characteristics, application limitations, and consequences of improper use of this equipment.
1.6 LIMITATIONS: Always consider the following limitations when using the HLL:
• Anchorage: Structure on which the HLL is mounted must meet the Anchorage specifi cations defi ned in Table 1.
• Fall Path and SRL Locking Speed: A clear path is required to assure positive locking of an SRL. Situations which do
not allow for an unobstructed fall path should be avoided. Working in confined or cramped spaces may not allow the
body to reach sufficient speed to cause the SRL to lock if a fall occurs. Working on slowly shifting material, such as
sand or grain, may not allow enough speed buildup to cause the SRL to lock.
• Hazards: Use of this equipment in areas with environmental hazards may require additional precautions to prevent
injury to the user or damage to the equipment. Hazards may include, but are not limited to: heat, chemicals,
corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp edges, or
overhead materials that may fall and contact the user or Personal Fall Arrest System.
• Fall Clearance: There must be suffi cient clearance below the user to arrest a fall before the user strikes the ground
or other obstruction. Fall Clearance is infl uenced by the following factors:
• Deceleration Distance
• Free Fall Distance
See the Personal Fall Arrest System manufacturer's instructions for specifi cs regarding Fall Clearance Calculation.
Where provided with Engineered Systems
specifi cs regarding system design and fall clearance calculation.
Changes in system location, equipment placement, etc. require review and revision of original clearance calculations.
Contact the Certifi ed Installer or 3M Fall Protection for assistance.
• Swing Falls: Swing Falls occur when the anchorage point is not directly above the point where the fall occurs (see
Figure 3). The force of striking an object while swinging from the pendulum effects of a Swing Fall can cause serious
injury (Figure 3-1). Swing Falls can be minimized by limiting the horizontal distance between the user and the
anchorage point (H). In a Swing Fall, the total vertical fall distance will be greater than if the user had fallen directly
below the anchorage point, thus increasing Fall Clearance required to safely arrest the user's fall (Figure 3-2). See
the PFAS manufacturer's instructions for details regarding Swing Falls and Fall Clearance calculation.
• Sharp Edges: The HLL System must be installed so defl ection of the anchor line in a fall arrest does not bring the
anchor line into contact with a sharp edge or any other article that may damage the anchor line.
Avoid working where Lifeline or Lanyard components of the attached Personal Fall Arrest System (PFAS) can contact
or abrade against unprotected sharp edges (see Figure 4). Where contact with a sharp edge is unavoidable, cover
the edge with protective material (A).
1 Competent Person: One who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or
dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
2 Installation Documentation: 3M Engineered Systems require installation by a 3M Certifi ed Installer. On completion of the installation, the Certifi ed Installer will
provide an Installation Packet (see Section 3 - Installation).
3 Engineered System: An application specifi c fall protection system designed, analyzed, evaluated, specifi ed, and installed by a 3M Certifi ed Installer.
4 Certifi ed Installer: A person certifi ed by 3M with extensive knowledge, training, and experience in the fall protection and rescue fi eld who is capable of designing,
analyzing, evaluating, and specifying fall protection and rescue systems to the extent required by applicable regional and national standards.
