bottom connector of the SRD to their location by pulling on the tagline.

Ensure the free end of the tagline does not become entangled with other workers, equipment, or machinery. If
necessary, restrain the free end of the tagline.
4.5 USING TWIN-SRD MODELS: Twin-SRD models, when mounted on a harness, may be used for Fall Arrest or Restraint
applications. Additionally, Twin-SRDs may be used for climbing applications, such as ascending or descending a rebar
structure. Twin-SRDs enable the user to maintain 100-percent tie-off when moving between anchorage points. As long as
one SRD is secured to an anchorage point, the user may disconnect the other SRD and move it to a different anchorage
point. By disconnecting and reconnecting each SRD in turn, the user may travel along a surface and still maintain tie-off
during movement.
The user must always consider the following before using a Twin-SRD:
• When in the vicinity of a fall hazard, the user must always have at least one SRD connected to an anchorage point.
Never connect both SRDs to the same anchorage point. See Figure 12.1 for reference.
• Each individual anchorage point must be strong enough to meet the anchorage requirements listed in Table 1.
• The individual SRDs must only be used to secure to anchorage points. Never secure two workers via the same
system. See Figure 12.2 for reference.
• The lifeline of each SRD must always be kept free from obstructions and entanglement. Do not pass either SRD under
arms or between legs during use.

4.6 USE WITH HORIZONTAL SYSTEMS: The SRDs covered in this instruction are compatible for use with horizontal
systems, such as Horizontal Lifeline (HLL) systems and horizontal rail systems. See the manufacturer instructions of your
horizontal system for more information on its compatibility with SRDs. SRDs may be used with a horizontal system only if
both products allow for such use.
;
Required Fall Clearance values presented in these instructions are based on use with a rigid, stationary
anchorage point. These values do not apply when the product is used with a Horizontal Lifeline (HLL) system. See the
manufacturer instructions of your HLL system for fall clearance charts specific to that system, or for additional factors
that must be accounted for before using the charts in these instructions.
4.7 AERIAL WORK PLATFORMS: Use of the SRD on aerial work platforms is permissible, provided the following criteria are met:
1. SRDs generally will not restrain workers from falling out of aerial work platforms or elevated working surfaces. To
restrain users from falling out of aerial work platforms, Positioning Lanyards of sufficiently short lengths should be used.
2. Aerial work platforms must have guardrails or gates at all accessible edges along their perimeter unless anchorages
for the SRDs are located overhead. The edges on the top rails of all guardrails and gates over which the user might
fall must have a minimum radius of 1/8 in. (0.3 cm).
3. Anchorages of appropriate strength and compatibility must always be used for securing SRDs (see Section 1.4).
4.
Swing fall hazards may exist, especially when working near corners or out away from anchorage points. Added fall
clearance is needed where the potential for swing fall exists (see Figure 5).
5. All sharp edges which the SRD’s lifeline may contact during a fall must be eliminated or covered over. All edges the
SRD lifeline may contact in a fall must be smooth with an edge radius of 1/8 in. (0.3 cm) or greater. Potential pinch
points between adjacent surfaces where the lifeline may catch during a fall must be eliminated.

After equipment has been removed from service, it may not be returned to service until a Competent Person confirms in
writing that it is acceptable to do so.
