3.0 Installation
3.1 PLANNING:
Plan your fall protection system before starting your work. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements and limitations defined in Section 2.
3.2 ANCHORAGE:
Figure 7 illustrates typical SRD anchorage connections. Select an anchorage location with minimal free fall and
swing fall hazards (see Section 1). Select a rigid anchorage point capable of sustaining the static loads defined in Section 1.
3.3 HARNESS CONNECTION:
A Full Body Harness is required for Fall Arrest applications. Connect the Snap Hook (A) on the
SRD Lifeline to the Back Dorsal D-Ring (B) on the Full Body Harness (see Figure 8). For situations such as ladder climbing,
it may be useful to connect to the front Sternal D-Ring. Consult the harness manufacturer’s instructions for details
regarding use of the harness connection points.
4.0 OPERATION
;
First time or infrequent users of Self-Retracting Devices (SRDs) should review the “Safety Information” at the
beginning of this manual prior to use of the SRD.
4.1
BEFORE EACH USE:
Before each use of this fall protection equipment carefully inspect it to assure it is in good working
condition. Check for worn or damaged parts. Ensure all bolts are present and secure. Check that the lifeline is retracting
properly by pulling out the line and allowing it to slowly retract. If there is any hesitation in retraction the unit should be
removed from service and destroyed. Inspect the lifeline for cuts, frays, burns, crushing and corrosion. Check locking
action by pulling sharply on the line. See the Inspection and Maintenance Log (Table 3) for inspection details. Do not use
if inspection reveals an unsafe condition.
4.2
AFTER A FALL:
Any equipment which has been subjected to the forces of arresting a fall or exhibits damage consistent
with the effect of fall arrest forces as described in Table 3, must be removed from service immediately and destroyed.
4.3
BODY SUPPORT:
A full body harness must be worn when using 3M SRDs. For general fall protection use, connect to
the back Dorsal D-Ring. For situations such as ladder climbing, it may be useful to connect to the front Sternal D-Ring.
Consult the harness manufacturer’s instructions for details regarding use of the harness connection points.
4.4
FALL ARREST CONNECTIONS:
When using a hook to make a connection, ensure roll-out cannot occur (see Figure 5).
Do not use hooks or connectors that will not completely close over the attachment object. Do not use non-locking snap
hooks. The anchorage must meet the anchorage strength requirements stated in Section 1. Follow the manufacturer’s
instructions supplied with each system component.
4.5 OPERATION:
Prior to use, inspect the SRD per the inspection procedure of Table 3. During use, connect the SRD to
a suitable anchorage or anchorage connector as previously described. Connect the Self-Locking Snap Hook on the end
of the lifeline to the Dorsal D-Ring on the Full Body Harness (see Figure 8). Ensure connections are compatible in size,
shape, and strength. Ensure hook is fully closed and locked. Once attached, the worker is free to move about within
the recommended working area at normal speeds. A tag line may be required to extend or retract the lifeline during
connection and disconnection operations. A tag line can be used to prevent uncontrolled retraction of the lifeline into the
SRD. Depending on the work site environment and conditions, it may be necessary to restrain the free end of the tag line
to prevent interference and entanglement with equipment or machinery.
4.6
HORIZONTAL SYSTEMS:
In applications where the SRD is used in conjunction with a horizontal system (i.e. Horizontal
Lifeline, Horizontal I-Beams Trolley), the SRD and horizontal system components must be compatible. Horizontal systems
must be designed and installed under the supervision of a qualified engineer. Consult the horizontal system equipment
manufacturer’s instructions for details.
;
Fall Clearance values in Figure 4 are based on anchoring to a rigid, stationary anchor point and do not apply to
anchoring to a Horizontal Lifeline (HLL) system. Consult the HLL Instruction Manual and HLL Installer to determine
required Fall Clearances.
5.0 Inspection
5.1
RFID TAG:
The Self-Retracting Device includes a Radio Frequency Identification (RFID) tag (see Figure 9). The RFID
tag can be used with the handheld reading device and web based portal to simplify inspection and inventory control and
provide records for your fall protection equipment. For details, contact a 3M Customer Service representative (see back
cover). Follow the instructions provided with your handheld reader, or on the web portal, to transfer your data to your
web log.
5.2
INSPECTION FREQUENCY:
The Self-Retracting Device must be inspected at the intervals defined in Section 2
.
Inspection procedures are described in the
“Inspection & Maintenance Log” (Table 3)
.
;
Extreme working conditions (harsh environments, prolonged use, etc.) may require increasing the frequency of
inspections (see Table 2).
5.3
UNSAFE OR DEFECTIVE CONDITIONS:
If inspection reveals an unsafe or defective condition, remove the SRD from
service immediately and discard (see Section 6).
;
Only 3M or parties authorized in writing may make repairs to this equipment.
