Figure 10: RESCUE
Lowering from an anchor: follow instructions on figure
8a and 8b.
Double person load on working line (Figure 10a): The
rescuer fastens the descender to his harness and
connects the injured person by means of an additional
connecting element.
Simultaneous descent of the rescuer and the victim on
separate lines (Figure 10b): This technique is only safe
with a double stop descender (SIRIUS) on victim. The
rescuer gradually pulls the victim's handle by means of
a cordelette as he/she descends so that the victim's
descent is initiated and kept constant. Be mutually
secured. For a smooth descent, higher tension of the
victim's free rope is recommended.
WARNINGS: Rescue and evacuation manoeuvres may
only be practiced by persons specifically trained for the
purpose. For all rescue manoeuvres the use of gloves
is recommended. To avoid loss of control and rope
damage (heat), lower descent speeds are advisable
during rescue operations.
Figure 11: PARALLEL DESCENDERS DESCENT
Parallel descenders technique may be adopted in cases
were risk assessment discloses more established
methods as unsafe. Both single person (11a) and
double person (11b) loads are applicable. With light
loads consider that force on each descender is halved.
Figure 12: BELAYING
All three versions with single dynamic ropes (EN 892)
within the specified diameter range are suitable for lead
climbing. Always hold the free end of the rope! Pay the
rope out by making a bight in the free end and pressing
on the cam to open it with one hand while pulling the
rope out of the descender with the other (fig. 12a). Take
the rope in by pulling it through the descender in
reversed direction (fig 12b). To lower a climber, follow
procedures as during descent. The braking effect is
dependent on rope diameter, rope slipperiness, etc.
Familiarize yourself with the braking effect before use.
