energy absorber installed on each end of the system. See Figure 1. Systems that are more than 30 ft. in
length must include an intermediate bracket for every 30 ft. span. The span length must be reduced when
clearance is limited. See section 3.3 for clearance information.
B. ANCHORAGES: The Sayfline horizontal lifeline must be installed on anchorages that meet the requirements
specified in section 2.5.
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.
D. CONNECTING SUBSYSTEM: Each person's connecting subsystem must limit fall arrest forces to 900 lbs. or
less. See section 2.6.
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. The personal fall arrest system
must be rigged to limit free falls to six feet or less when using an energy absorbing lanyard, or such that the
SRL is overhead and without slack, according to OSHA 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 DBI/
SALA 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 3.3 for required clearance information.
H. BODY SUPPORT: Sayfline Multi-span Wire Rope Horizontal Lifelines must only be used with personal fall
arrest systems incorporating a full body harness.
I.
PHYSICAL AND ENVIRONMENTAL HAZARDS: Use of this equipment in areas with physical or
environmental hazards may require additional precautions to reduce the possibility of 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, gases, moving machinery, and sharp edges. Contact DBI/SALA if
you have questions about using this equipment where physical or environmental hazards exist.
J. TRAINING: This equipment must be installed and used by persons trained in the correct application and use
of this equipment. See section 5.0.
1.3
APPLICABLE STANDARDS: Refer to national standards, including ANSI Z359.1-1992, and local, state, and
federal (OSHA 1910.66 and 1926.502) requirements for more information on personal fall arrest systems and
associated components.
2.0
SYSTEM REQUIREMENTS
2.1
PERSONAL FALL ARREST SYSTEM COMPONENTS: The Sayfline horizontal lifeline must be used with
DBI/SALA 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. The
connecting subsystem between the harness and horizontal lifeline must limit fall arrest forces to 900 lbs. or less.
2.2
COMPATIBILITY OF CONNECTORS: Connectors are considered to be compatible with connecting elements
when they have been designed to work together in such a way that their sizes and shapes do not cause their gate
