3.0 Application
3.1
Purpose:
The FallTech DuraTech Leading Edge SRL is designed to be used as a component in a Personal Fall Arrest System (PFAS), to
provide a combination of worker mobility and fall protection as required for inspection work, general construction, maintenance work, oil
production, confined space work, etc. The Class 2 SRL is intended for fall protection in Leading Edge applications where falls may occur
over edges.
3.2
Personal Fall Arrest System:
A PFAS is an assembly of components and
subsystems used to arrest a person during a fall event. A PFAS typically
consists of an anchorage, a deceleration device such as a Energy Absorbing
Lanyard (EAL), a Self-Retracting Device (SRD), or a Fall Arrestor Connecting
Subsystem (FACSS), and a properly fitted Full Body Harness (FBH). Maximum
permissible free fall in a typical PFAS is 6’ (1.8 m). The SRD discussed in this
manual may be used in non-overhead anchorage situations. Clearance
calculators provided in this manual offer methods for calculating MRFC for
non-overhead anchorage locations when the SRD is set back from 0’ to
4’ (1.2 m) and non-overhead anchorage locations that are set back 5’ (1.5m) or
greater, see Figure 2.

4.0 System Requirements
4.1
Capacity:
The SRD is designed for use by a single user with a combined weight of user, tools, clothing, etc., of 130–310 lbs (59-141 kg).
4.2
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 mechanisms to inadvertently open regardless of how
they become oriented. Contact FallTech if you have any questions about compatibility. Connectors must be compatible with the
anchorage or other system components. Do not use equipment that is not compatible. Non-compatible connectors may unintentionally
disengage. Connectors must be compatible in size, shape, and strength. Self-closing, self-locking connectors are required by ANSI and
OSHA.
4.3
Compatibility of Components:
Equipment is designed for use with approved components and subsystems only. Substitutions or
replacements made with non-approved components or subsystems may jeopardize compatibility of equipment and may affect the safety
and reliability of the complete system.
4.4
Making Connections:
Only use self-locking connectors with this equipment. Only use connectors that are suitable to each application.
Ensure all connections are compatible in size, shape, and strength. Do not use equipment that is not compatible, see Figure 3.
Visually ensure all connectors are fully closed and locked. Connectors are designed to be used only as specified in each product’s user’s
instructions.
3.3
Horizontal Lifeline (HLL) and Rail Systems:
The SRD may be attached to rigid and flexible anchors provided that all HLL or rail system
applications, installation, and uses are under the supervision of a Qualified Person.
3.4
Rescue:
Ensure a written rescue plan, method and system is in place and readily available for rapid response. Rescues may require
specialized equipment or measures. Rescue operations are beyond the scope of this manual. See ANSI Z359.4 and Z359.2.
3.5
Application Limits:
The SRD discussed in this manual is designed for Leading Edge applications. However, take caution to avoid very sharp
edges such as sheared metals, metals cut with an abrasive disk, or flame-cut metals. Also take caution around very abrasive surfaces and
edges, such as concrete or stone, as these edges and surfaces may abrade the lifeline or the energy absorber during a fall event.
