One or more climbers descended the line uneventfully, but a following (inexperienced) climber on the club team (apparently using a megajul; configuration tube/brake assist unknown) lost control during their descent. Despite a firemans belay the climbers fall was slowed but not completely arrested. The climber suffered a burn/abrasion injury to their hand.

Re the Edelrid 6 mm used as single strand for abseiling...
The Edelrid website has an associated downloadable pdf for usage of this specialist rope.
It is quite clear in the pictographs of that file that the rope is meant to be used double, or if mixed with a larger diameter rope to either abseil on both together or block off the thin 6 mm strand and abseil the thicker diameter strand, and even then, with caution and due attention to rigging correctly in both cases!

Re using a megajule abseil device with it as a doubled strand abseil; it clearly indicates that two karabiners are meant to be used in conjunction with the megajule to provide manageable friction.

ODH’s treatise should be compulsory reading for all members of the club involved...
