Application - Falltech DuraTech C83709SB7 Manuel De L'utilisateur

2.1 Canadian Standards Organization (CSA): The FallTech SRD described in this manual, when used per the instruction in this manual
meets 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 DuraTech 9' Cable Self Retracting Device in this manual is Class SRL.
CSA Test Parameters used in this manual are:
• Arrest Distance (AD)
• Average Arrest Force (AAF)
• Maximum Peak Arrest Force (MPAF)
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 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.
This test data is then used to establish the basis for fall clearance guidelines published in the user instruction manual.

Application

3.1 Purpose: The FallTech® 9' DuraTech Cable 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 DuraTech SRD is intended for Personal Fall Arrest applications
only. 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 a back-up PFAS.
3.2 Personal Fall Arrest System: A PFAS is typically composed of an anchorage and a FBH, with an energy absorbing connecting device,
i.e., a EAL, a 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.
3.3 SRD Orientation in Fall Arrest: The 9' DuraTech SRD is a versatile design, capable of multiple attachment orientation options, see
Section 3.3.1.
3.3.1 Single SRD: One SRD with two orientation options;
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, see Figure 3.
The anchorage may be anywhere in the allowable anchorage range, from overhead (directly overhead to the level of the D-ring) to
non-overhead (down to the level of the Dorsal D-ring for a 141 kg (310 lb)) user.
As a single-leg SRD with the housing end attached to an anchorage and the leg end connected to the FBH dorsal D-ring, see Figure 4. The
anchorage may be anywhere in the allowable anchorage range, from overhead (directly overhead to the level of the D-ring) to
non-overhead, the level of the D-ring.

NOTE: Lateral movement will result in a significant increase to fall clearance distance and swing fall requirements. See Section 4.
3.4 Application Limits: Take action to avoid moving machinery, sharp edges, abrasive surfaces, and thermal, electrical, or chemical
hazards as contact may cause serious injury or death.
DO NOT attach to a foot-level anchorage.
DO NOT use the SRD to lift tools, materials, or personnel.
Remove from service any equipment subjected to fall arrest forces.
