4.3 BODY
SUPPORT:
A full body harness must be worn when using DBI-SALA SRLs. 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.
IMPORTANT:
Do not use a body belt for free fall applications. See OSHA 1926.502 for guidelines.
4.4 MAKING
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 mounting surface should meet the anchorage strength requirements stated
in section 2.2. Follow the manufacturer’s instructions supplied with each system component.
4.5 OPERATION:
Inspect the SRL as described in section 5.0. Connect the SRL 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 7). 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. If the RSQ Selection Knob is set to ‘Fall
Arrest’, the SRL will arrest the fall. If the RSQ Selection Knob is set to ‘Descent’, the SRL will automatically
descend the user to a lower level when a fall occurs. When working with an SRL, always allow the lifeline
to recoil back into the device under control. 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 SRL. 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.
WARNING:
Do not tie or knot lifeline. Avoid lifeline contact with sharp or abrasive surfaces. Inspect
lifeline frequently for cuts, fraying, burns, or signs of chemical damage. Dirt, contaminants, and water can
lower dielectric properties of the lifeline. Use caution near power lines.
4.6 RSQ™ FALL ARREST/DESCENT MODE SELECTION:
Ultra-Lok™ RSQ™ Dual-Mode SRLs are equipped
with an RSQ Knob to select between the Fall Arrest or Descent operating modes of the SRL (see Figure 9).
To select Fall Arrest Mode or Descent Mode:
1. Pull the RSQ™ Engagement Knob outward.
2. Turn the RSQ™ Engagement Knob until the arrow on the face of the knob points to the Selection Notch
for the desired mode and the RSQ™ Engagement Knob clicks into place with the Selection Notch (as
illustrated in Figure 9).
IMPORTANT:
Ultra-Lok RSQ SRLs are designed for emergency fall arrest and descent and may only be used
for a single, vertical descent. If the SRL is used to descend, remove it from service immediately and send it to
an authorized service center for repair.
