Classification information found on product labels is based on test results. Table 1B in Appendix A
provides test performance results forthe SRD discussed in this manual. NOTE: Arrest distance is one of
several parts of the Minimum Required Fall Clearance (MRFC). MRFC is discussed in detail in Section 5 .
OSHA requires an SRD limit the free fall to 2 feet (0.9 m) or less. If the maximum free fall distance must
be exceeded, the employer must document, based on test data, that the maximum arresting force will
not be exceeded, and the personal fall arrest system will function properly. The SRD discussed in this
manual was successfully tested for horizontal use and falls over a steel edge without burrs, as found
on steel shapes and metal sheeting, and may be used in situations where a fall may occur over similar
edges, such as found on steel shapes or metal sheeting. Additional testing has been conducted on
a concrete edge substrate, outside and beyond the scope of ANSI Z359. Contact Falltech for more
information on this testing.
2.2 Canadian Standards Organization (CSA): The FT-X SRL-LE described in this manual, when used
per the instruction in this manual meets or exceeds CSA Z259.2.2-2017(R2022). 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 the activation 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 Arrest Force
is the maximum amount of force that may be applied to the body and the anchorage by the fall protec-
tion 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.
This test data is then used to establish the basis for fall clearance guidelines published in the user
instruction manual. See Table 1C.
3.0 Application
3.1 Purpose:
The 8' FT-X

TM
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 FT-X
applications where falls may occur over leading 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). The SRD discussed in this manual may be used in non-overhead
anchorage situations. Maximum permissible free fall in a typical PFAS is 6' (1.8 m). Other applications
may be below the D-ring, or horizontally in an approved FallTech SRL rotating anchor, designed for
such use.
3.3 Horizontal Lifeline (HLL) and Rail Systems:
The SRL 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.
