To install the SRD on the harness see Figure 5A. Follow these steps:
1.
Don the harness in accordance with the harness manufacturer’s instructions.
2.
Insert the nose end of an ANSI compatible double-locking carabiner through the SRD housing swivel eye.
3.
Attach the carabiner to the dorsal D-ring of the FBH. Ensure the carabiner is oriented with the lock opening up and will take the load
along its major axis. Visually ensure the carabiner closes and locks securely.
4.
Connect the leg end connector to an approved, suitable anchor that meets work zone requirements.
The SRD will pay out and retract smoothly to maintain a taut line during normal movement. Work as directly under the anchor as possible. Be
aware that a lower anchorage increases the risk of injury due to swing fall. Additional fall clearance is required.
DO NOT
use a rebar hook or any large-throat snap hook or large carabiner to install the housing on the FBH, as this could cause a side load on the
gate and create an unintentional disengagement.
Housing attached to the anchorage
: A single-leg SRD with the housing end attached to an anchorage and the leg end connected to the user’s FBH.
The anchorage may range from overhead, to as low as 5' below the dorsal D-ring for a worker up to 310 lbs maximum. . Connect the leg end
connector to the dorsal D-ring.
Be aware that a lower anchorage increases the risk of injury due to swing fall. Additional fall clearance is required.
To attach the housing to an anchorage, see Figure 5B and follow these steps;
1.
Don the harness in accordance with the harness manufacturer’s instructions.
2.
Insert the nose end of an ANSI compatible double-locking carabiner through the SRD housing swivel eye.
3.
Attach this carabiner to the anchor point. Ensure the carabiner is oriented with the lock opening up and will take the load along its major
axis. Visually ensure the carabiner closes and locks completely.
4.
Connect the leg end connector to the dorsal D-ring of the FBH. Visually ensure the connector closes and locks completely.
The SRD will pay out and retract smoothly to maintain a taut line during normal movement. Work as directly under the anchor as possible. Be
aware that a lower anchorage increases the risk of injury due to swing fall. Additional fall clearance is required.
DO NOT
use a rebar hook, or any large-throat snap hook, or large carabiner to connect the leg end to the FBH. A side load on the gate could cause
an unintentional disengagement. Use small-throat opening connectors only.
4.5.2 Twin-leg SRDs:
Twin-leg SRD housing ends are attached to the straps of a properly adjusted and fitted FBH with a specially-configured triple-
locking twin-SRD carabiner. Connect the leg ends to anchorages within the correct orientation range. See Figure 2.
DO NOT
attempt to install the twin SRDs specially configured carabiner to an anchorage.
CAUTION:
Do NOT connect the leg ends of twin SRDs to two anchorages at the same time, except for the brief time when transitioning from one
anchorage to another. See paragraph 4.5.4, and Figure 7.
4.5.3 Install the Twin-SRD:
To install the SRD housings onto the FBH, follow the procedure detailed in Figure 6.
1.
Prepare Twin-leg SRD for Attachment
2.
Prepare FBH and Preliminary Attachment
3.
Reinstating 2nd SRD Unit
4.
Closing and Securing
WARNING
Ensure the carabiner is correctly installed on the FBH as shown in Figure 6. Incorrect installation may result in serious injury or death.
Figure 6B shows common incorrect connections.
4.5.4
Twin-leg SRD Work Zone Transition:
This SRD is designed for attachment of one leg end at a time during work performance.
Dual connection
is for transitioning
from one work zone to another only, as shown in Figure 7.
Attach one leg end connector to a suitable anchor. The user may then move to another work location and attach the unused leg to another
suitable anchorage. Detach the original attached leg. Repeat the procedure, until the desired work location is reached.
4.6 Locking Speed:
The SRD utilizes a centrifugal locking mechanism. The locking function requires a certain payout rate during a fall event to
function correctly.
If a fall occurs, a pawl mechanism is engaged, which locks the drum, halting payout. The energy absorber deploys to slow and
arrest the fall.
Certain situations, confined or cramped spaces, shifting footing such as sand, gravel, grain, or a sloped surface may not allow the
lifeline to reach sufficient speed to activate the lock mechanism. A clear path is required to assure positive locking of the SRD.
4.7 Impact Indicator:
The shock absorber is the fall arrest impact indicator for this unit. Torn stitching, expansion or lengthening, of the shock
absorber is an indication that a fall event has occurred. If you have any questions contact FallTech.
Inspect the unit before each use in accordance with the instructions in this manual. If any of the above conditions are evident, remove the SRD
from service immediately.
DO NOT
allow the lifelines to become tangled or twisted together as this may prevent them from retracting.
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 freewheel back into the housing.
After a Fall:
Remove from service immediately any equipment subjected to fall arrest forces, or exhibiting damage consistent with the effects of fall
arrest forces.
5. SPECIFICATIONS
See Table 1A, 1B, and 1C.
6. MAINTENANCE, SERVICE AND STORAGE
6.1 Maintenance:
Keep the SRD free of contaminants such as paint, grease, grit and chemicals as this may hinder lifeline functions. Keep debris
from entering the housing through the lifeline port. Clean the exterior of the unit as required with a soap/water solution. Do not allow any water
inside the housing. After cleaning, pull the lifeline all the way out, allow the unit to air dry, then retract the lifeline into the unit. Do not allow the
lifeline to freewheel into the housing. Maintain tension.
DO NOT
use heat to dry.
DO NOT
attempt to disassemble the SRD.
