Improvised Single Point Lowers (Figures 10:1 and 10:2)
10.1 The improvised methods shown in this section would
only be used when, because of fire or other emergency combined with a lack of
equipment, immediate evacuation of the casualty is imperative.
The techniques are normally used with a Chair knot or a
stretcher and consist of taking two round turns around a sound anchor point as a
belay. The rope should be paid out hand-over-hand and the rescuer must wear
gloves. A more satisfactory single point lower technique, can be achieved with a
mechanical descender (Para 10.11 refers).
