Step 4. Remove the retaining pin so that the lower section of the Rescue Box can be removed. Pull
one end of the rope lifeline through the R520 unit until only a foot of lifeline remains at one
end. Carefully coil up the remainder of the lifeline and insert in the lower section of the Rescue
Box as shown. The lifeline must be capable of deploying completely without tangles or snags.
Secure the lower section using stud (E) and retaining pin (F).
• Supplied in backpack bag: The R520 Escape Device can be supplied in kit form, with accessories and
various rope lengths, for storage in a backpack style bag.
3.4 SINGLE PERSON UNASSISTED ESCAPE: Procedures for performing and unassisted descent with the
R520 Escape Device are as follows:
WARNING:
The users of this equipment must be in good physical condition. The user must have the ability to absorb the landing.
Step 1. Connect to a Full Body Harness or other
Body Support: A full body harness or other
means of supporting the user must be used
with the R520 Escape Device.
WARNING:
equipment. Body belts do not support your
entire body, which may result in serious injury.
When using a full body harness, connect
the Snap Hook on the lifeline to the front or
back D-ring (Figure 5). Ensure the D-ring is
positioned to hold the user upright. See the
full body harness manufacturer's instructions
for more information.
Step 2. Prepare the Lifeline: Pull out the pin that
secures the lower Rescue Box body (Figure
4 F). Allow the lower Rescue Box body to fall
away. Lower one end of the lifeline to the
ground or landing below. Ensure the lifeline
is free of knots or kinks.
Step 3. Prepare for Descent: Prior to descent, the
section of the lifeline between the user and the
R520 Escape Device must be tightened to remove
any slack. Tighten the lifeline by pulling on the
free end of the rope until slack between the user
and R520 Escape Device is removed. Once the
lifeline is taut, hold the free end of the lifeline
tightly until descent is initiated.
NOTE:
truck (EWP) after connecting to the life line, the user
should limit the slack in the lifeline. This will reduce
stress on the user when initiating the descent.
Step 4. Descend to Safety: Release the free end of the
lifeline to initiate descent. Descent speed will be
automatically controlled to a rate of .6 - .9 m/s
(2-3 ft/s) by the R520 Escape Device's centrifugal
brake.
NOTE:
attempting to slow or stop descent. Descent may be
interrupted by firmly grasping the free end of the
lifeline. (A, Figure 6)
For increased ease of control of descent speed,
the free end of the lifeline can be looped through
notch (B, Figure 6) on the same side of the unit.
Apply pressure to the free end of the lifeline during
descent to control descent speed.
Bend your knees to prepare for landing. After landing, disconnect the lifeline from the body
support.
