1. DESCRIPTION
The FallTech® DuraTech™ 6' Mini Single/Twin SRD is a self-retracting lifeline for those working at height and subject to fall hazards. The DuraTech 6'
Web Mini Single/Twin SRD
This manual contains two Appendices, Appendix A and Appendix B. Appendix A contains figures and tables specific to the SRD discussed in this
manual. Appendix B contains figures and tables applicable to fall protection equipment in general. All figure, table, and chart references in this
manual are to Appendix A unless otherwise noted.
For purposes of this manual, the SRD may be referred to as the SRD, the equipment, the device, the product, or the unit.
A the top of the unit, a swiveling steel eye provides an attachment point for a self-closing and self-locking connector. The SRD body consists of a
nylon housing containing a 6' length of high performance polyethylene and polyester fiber webbing wound onto a spring-tensioned drum. The
drum is equipped with a pawl system that locks the drum shaft and halts lifeline payout in a fall event. An integrated energy absorber at the leg
end of the lifeline slows and arrests the fall, and also functions as a fall arrest indicator.
When attached and the worker moves about, the lifeline pays out and retracts, automatically maintaining a taut line.
See Tables 1-A, 1-B and 1-C, and Figure 1. The user of the equipment discussed in this manual must read and understand the entire manual before
beginning work.
1.2 ANSI Standards and OSHA Regulations:
The device discussed in this manual complies with ANSI standards Z359.0, Z359.1, Z359.7, Z359.2, and
Z359.14. This unit also complies with OSHA 1926 regulations.
Z359.14 sets performance requirements for SRDs, based on dynamic testing. There are two classifications; Class A, and Class B. The SRD discussed
in this manual has been tested in accordance with ANSI Z359.7, and conforms to ANSI Z359.14 standards for a Class B device. These tests include
Dynamic Performance Testing, Dynamic Strength Testing, Static Strength Testing, and Retraction Tension Testing. The SRD was also tested for Static
Strength per OSHA regulations. See paragraph 3.5.1.
2. APPLICATION
2.1 Purpose:
An SRD is designed for use as a component in a 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 or any application where fall protection and worker
mobility is required. The SRD is not designed nor suited for use in restraint, personnel riding, suspension, work positioning, or rescue applications.
Do NOT use the SRD for these applications except as part of a back-up PFAS.
2.2 Personal Fall Arrest System:
A PFAS is typically composed of an anchorage and a FBH, with an energy absorbing connecting device, i.e., a SAL,
an SRD, or a Fall Arrester Connecting Subsystem (FACSS), attached to the dorsal D-ring of properly fitted and adjusted FBH. All uses and
applications of a FBH with this equipment requires the FBH to be properly fitted and adjusted to the user. Failure to properly fit the FBH to the user
could result in serious injury or death.
The SRD may be installed on a FBH, or attached to a suitable anchorage. See Section 4 for additional details.
2.3 SRD Orientation In Fall Arrest:
The 6' SRD is a versatile design, capable of multiple attachment orientation options, either as a single-leg unit,
or as a twin-leg unit, as shown in Figures 2. The SRD may be attached in an overhead orientation as shown in Figure 3A, or in a non-overhead
orientation, where the anchor attachment may be a maximum of 5' below the user's FBH dorsal D-ring as shown in Figure 3B. See Section 4 of this
manual for installation and use.
2.3.1 Single SRD:
One SRD with two orientation options. The anchorage may be anywhere in the allowable anchorage range, from overhead
(directly overhead to the level of the D-ring) to non-overhead. Non-overhead is defined as level with the D-ring, to a maximum of 5' below the D-
ring. The SRD may be oriented as follows;
•
as a single-leg SRD with the housing end attached to the dorsal D-ring of a FBH and the leg end connected to an anchorage.
•
as a single-leg SRD with the housing end attached to an anchorage and the leg end connected to the FBH dorsal D-ring.
