Falltech FT-R SRL Manuel De L'utilisateur page 6

2.2 Canadian Standards Organization (CSA):
The FT-R SRL-LE described in this manual, when used per the instruction in this manualmeets or
exceeds CSA Z259.2.2-2017. CSA requires that all SRDs be classified according to their respective type,
and are classified either as; Class SRL, Class SRL-R, Class SRL-LE, or Class SRL-LE-R. The FT-R SRL-LE Self
Retracting Device in this manual is Class SRL-LE.
CSA Test Parameters used in this manual are:
•
Arrest Distance (AD)
•
Average Arrest Force (AAF)
•
Maximum Arrest Force (MAF)
The Arrest Distance is the total vertical distance required to arrest a fall. The Arrest Distance includes
the deceleration distance and theactivation distance. The Average Arrest Force is the average of the
forces applied to the body and the anchorage by the fall protection system. The Maximum Peak Arrest
Force is the maximum amount of force that may be applied to the body and the anchorage by the
fall protection system. In addition to the above tests conducted in ambient conditions, the units must
be retested for average and peak forces under certain environmental conditions, where the units are
cooled, then tested, and saturated in water and tested again. Separate units are used for each test. All
test results are recorded.
3.0 Application
3.1 Purpose:
The FallTech FT-R 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
SRL-LE 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 Shock Absorbing Lanyard
(SAL), 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.

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.
