;
The R550 Rescue & Escape Device may become hot during use which could injure the user if parts other
than those used to control the descent are touched. Use beyond the specified load and descent length limits may
generate excessive heat which could damage the descent line.
4. Prepare for the Next Descent: After use of the R550 Oil & Gas Rescue System, the lifeline must be pulled through
the device as needed to position a lifeline end and Snap Hook adjacent to the next person to descend.
REMOTE ASSISTED RESCUE: See Figure 15.1. The R550 Rescue System is equipped with a Rescue Hub (RH) which
can be used in remote assisted rescues to raise the fall victim to permit removal of their fall arrest subsystem (lanyard,
etc.) prior to descent to safety. Procedures are as follows:
1. Lower or Raise One End of the Lifeline to the Victim: Pull the lifeline (L) through the R550 Rescue System (A)
as needed until the snap hook (B) on one end of the lifeline is adjacent to the desired connection point on the victim's
body support (C).
Connect to the Victim's Full Body Harness or other Body Support: Connect the snap hook (B) on the rescue
2.
end of the lifeline to the sternal D-ring or dorsal D-ring (C) (also see Figure 14 for D-ring locations). Ensure the
D-ring is positioned to hold the user upright.
;
In the event the connection point on the victim's body support is not within reach, the rope grab accessory (Figure 15.3,
D) can be attached upside down (
can be attached to the eye (E) on the rope grab (D) and the rescue hub (RH) can be used to raise the victim to safety or to a
point where their initial fall protection system can be released to allow lowering the victim to safety.
3. Raise the Victim to Disconnect the Fall Arrest Subsystem: Rotate the Rescue Hub (RH) to raise the victim's
weight from the fall arrest subsystem and onto the R550 Rescue & Escape Device. Secure the Free End of the lifeline
with the R550 Descender's Pigtail and Cam Cleats to prevent unintentional descent (see Figure 16). Disconnect the
Victim's fall arrest subsystem (Lanyard, etc.).
Alternate Option (See Figure 16): The R550 Rescue & Escape Device is also configured to allow a Power Drill
•
(minimum 12 mm chuck and 45 N-m torque) to be attached to the center of the Rescue Hub which can be used
in remote assisted rescues to raise the fall victim. (See Table 1 for an example of lifting distances.) Attach the
Power Drill directly to the shaft at the center of the Rescue Hub (see Figure 16). Use the attached Power Drill to
rotate the Rescue Hub to raise the victim's weight from the fall arrest subsystem and onto the R550 Rescue &
Escape Device. Secure the Free End of the lifeline with the R550 Rescue and Escape Device's Pigtail and Cam
Cleats to prevent unintentional descent (see Figure 15). Detach the Power Drill by lowering the victim's weight
onto the unit's Pigtail and Cam Cleats and then releasing the Power Drill from the center of the Rescue Hub.
Once the Powered Drill is removed, disconnect the Victim's fall arrest subsystem (lanyard, etc.).

** High speeds with high loads not recommended.
;
Power Drill lifting capabilities will vary with victim load, battery charge, drill model, and environmental
conditions. The lowest drill speed setting is recommended to maximize battery life and to reduce the risk of
damaging the drill or the R550 Descender. Loads greater than 141 kg should not be lifted with the Power Drill
option. Lifting in reverse direction will typically decrease the lifting distance capacity of a single battery charge.
4. Prepare the Lifeline for Descent: Prior to descent, the section of lifeline between the user and the
R550 Rescue System must be tightened to remove any slack. Tighten the lifeline by pulling on the free end of the
lifeline until slack between the user and R550 Rescue System is removed. Once the lifeline is taut, hold the free end
of the lifeline tightly until descent is initiated.
Descend to Safety: Release the free end of the lifeline to initiate descent. Descent speed will be
5.
automatically controlled to a rate described in Table 1 ("R550 Rescue System - Descent Requirements") by the
R550 Rescue System's centrifugal brake. Descent may be interrupted by firmly grasping the free end of the lifeline
(see Figure 15). Bend your knees to prepare for landing. After landing, disconnect the lifeline from the body support.
Record all descents in the Descent Log (Table 3).
;
The R550 Rescue & Escape Device may become hot during use which could injure the user if parts other
than those used to control the descent are touched. Use beyond the specified load and descent length limits may
generate excessive heat which could damage the descent line.
SIMULTANEOUS RESCUE AND ESCAPE: See Figure 15.2. In situations where the fall victim requires assistance,
simultaneous rescue and escape allows a rescuer to accompany the victim during descent:
;
Two person descents with the R550 Oil & Gas Rescue System should not exceed a total combined weight
(including tools, clothing, body support, etc.) of 282 kg and a descent distance of 200 m.
Descend to the Victim: In situations where the fall victim is suspended by their existing fall arrest subsystem, it will
1.
be necessary for the rescuer to descend to the victim's location to provide assistance. Descend to the victim per the
steps in Section 4.2 - "Single Person Unassisted Escape".
