The following describes what might be described as a near miss event when I was climbing with another club member, ClimberX, at a sport climbing crag in May 2021. I had been climbing all day with ClimberX in the quarry which is all bolted All routes finish with two bolts or staples on the headwall At no stage in the day did I (or ClimberX to my memory) ever shout safe. Take and slack were the only calls I used – as is the protocol for sport as you are only safe once back on the ground On the last route I followed the usual routine to lower. - Clip one bolt with a cows tail - Thread a bight of rope, without untying - Tied in to the bight on a krab - Untie the original in knot - Shout take – rope moved - Unclipped cows tail about to fully weight rope Looked down and found Climber X had unclipped me from the rope even though that had left me hanging on a single bolt 100ft up. At no stage did ClimberX check with me to see if it was OK to take me off belay. At that moment there was a bit of shouting, ClimberX froze and the team next to us stepped over and put me back on belay What this shows is that despite climbing regularly for many years, ClimberX has serious limitations on knowledge of safe protocols and/or very limited understanding of the underlying systems in play (both comms and ropes).
This is a 4 pitch climb. My climbing partner was leading the 3rd pitch and had to climb over a bulge to get to the next belay point, hence I couldn't see him anymore and it was harder to hear what he was saying. Soon after he went out of sight I heard him shout "safe" so I took him off belay. Then suddenly started to panic as I doubted whether he might have said "take" instead. Thankfully I was right and he was safe but that would have been one fatal mistake..
