Modern Arboricultural Services Essential Arb magazine article

This is a small extract from the artical, 

"For the final climb, a refresher of the basic rescue techniques, we move to an oak tree. This rescue is one where the casualty’s rope is long enough for them to reach the ground. While no longer mandatory to be performed in NPTC assessments, candidates must demonstrate knowledge of this: two people using two climbing systems that are still intact. 

Gert Brakel climbs the stem. Using three pulls up, Gert then feeds the excess rope through the hitch climber, preventing too much slack in the system and to stop him from dropping too far. As theteam spread throughout the tree, Kevin Moore says, “There is agood reason for preventing the slack. Your pelvis has three bones.
There is a limit to what they can withstand. If you fall in your harnessany further than half a metre on a single rope, your pelvis could pop. Everything we teach in tree surgery is about working within safe parameters. Your employer wants you to return home in the ame condition as you arrived at work.” 

Brian rescues a voluntarily unconscious Coleman. Pulling Coleman upright, Brian attaches a chest sling, wraps his legs loosely around him, lowers Coleman to the ground on his own system and lays him out in the recovery position. Kevin Moore observes that if branches need negotiating during a descent, the chest sling is necessary to keep the injured party upright. If the descent is clear, foregoing the chest sling and wrapping legs tightly around the injured party speeds up the descent. 

One team member uses single rope technique (SRT). The best way to rescue someone using SRT is to use their own pre-rigged access line. Kevin Moore ties two ‘Alpine Butterflies’ in the line. He attaches a second rope, via a carabiner, to the top knot. He threads the rope through a figure 8, which is secured to the lower knot. He mimes cutting the access line between the knots. “By adding these two knots and attaching our own line, we can lower the injured down on his access line.” We take our leave as the team begins their summing up. A quick straw poll of useful things taken from the day include learning the 112 emergency services number (instead of calling 999), how to identify where you are when working in remote locations (OS grid reference) and the multiple uses for the ‘Alpine Butterfly’ knot. All agree that the day was useful and a good reminder to use lessons that they may once have learned and subsequently forgotten."
