5.3.3 After A Fall:
A fall event over an edge may require special rescue equipment and measures. Ensure a written
rescue plan, method and system is in place and readily available to all users for rapid response. Ensure
all users are trained in rescue procedures. If a fall event occurs, remove it from service, and store it
separately. Remove from service any unit that has been subjected to fall arrest forces or that exhibits
damage consistent with such forces. For questions, contact FallTech.
5.3.4 Using the SRD:
Do not use the SRD if inspection shows damage or any malfunction. Don the FBH in accordance
with the FBH manufacturer's instructions. Follow the instructions contained in this manual and on
the labels. Failure to follow instructions may result in serious injury or death. Connect the SRL-FBH
Connector to the dorsal D-ring on the FBH. Ensure the connector closes and locks. Attach the leg-end
carabiner to the chosen anchorage and ensure the leg-end connector closes and locks. Ensure all
connections are compatible. Normal operation will allow the working length of the lifeline to extend
and retract as the worker moves about. A certain amount of tension must remain on the cable at all
times to ensure proper operation of the internal brake. Do not allow the lifeline to become slack. If the
lifeline becomes slack, remove the SRD from service for inspection. See Section 7.
Avoid sudden or quick movements during the normal work operation, as this may cause the SRD brake
to engage and possibly cause loss of balance and injury or death.
If a fall occurs, the brake will engage and lock the lifeline. The EA will deploy to arrest the fall and limit
arrest forces on the user.
•
DO NOT extend the lifeline past the operational limit.
•
DO NOT allow one SRD lifeline to become tangled or twisted with another SRD lifeline during use.
•
DO NOT allow any lifeline to pass under arms or between legs during use.
•
DO NOT clamp, knot, or prevent the lifeline from retracting or being taut.
•
DO NOT lengthen the SRD by connecting a lifeline or similar component.
•
DO NOT allow the lifeline to remain outside the housing when not in use.
5.3.4 CSA Z259.2.2-17(R2022) Deployment Data:
Deployment is equal to deployment factor times free-fall distance, h. See table below for deployment
factor.

5.4 Calculating Minimum Required Fall Clearance
5.4.1 FT-X in Overhead, Non-Leading Edge Anchorage Application
[130 to 310 lbs. (59 to 141 kg) user]
The FT-X may be used may be used as a standard SRD in an overhead condition, in which the SRD is
installed anywhere in the allowable attachment area, which ranges from directly above the user to
level with the FBH D-ring, as shown in Figure 9.
The overhead condition minimum required fall clearance (MRFC) is calculated using four metrics,
measured from the walking-working surface: SRD Deceleration Distance, D-Ring Shift and Harness
Stretch [1 ft (0.3m)], Safety Factor [1.5 ft (0.5m)], and Swing Fall. The diagram in Figure 11 is calculated
using the performance data of the SRD and includes all four metrics listed previously to determine the
MRFC.
5.4.2 FT-X with a Non-Overhead Anchorage Leading Edge Anchorage Application
[130 to 310 lbs. (59 to 141 kg) user]
The leading edge/below D-ring condition minimum required fall clearance (MRFC) is calculated using
five metrics, measured from the walking-working surface: SRD Deceleration Distance, D-Ring Shift and
Harness Stretch [1 ft (0.3m)], Safety Factor [1.5 ft (0.5m)], Dorsal D-ring Height [5 ft (1.5m)], and Swing
Fall. Dorsal D-ring height is added to account for the below D-ring tie-off compared to the overhead
condition.
