But looking at the details and photo of the faulty slings that require returning, would it be out of order to suggest that anyone using one of the faulty slings for any significant application could be a candidate for a Darwin Award?
Maj.
How many cavers put coloured insulating tape on their slings to mark them as their own? From my experience, most.
This is not the first time the tape splice issue has come up.
Back in the 1990's we were doing the first through trip of two newly connected caves in Matienzo. Everybody on the trip went down on properly rigged ropes and I was following behind and rigging pull throughs to retrieve the rope. We had purchased a 30m length of webbing tape from a UK supplier and I was cutting it as needed for the rigging.
At the top of one of the pitches I reeled out some webbing and made a 'Y' hang. In one of the legs of the 'Y' there was some insulating tape wrapped around the webbing. I never once imagined it would be a tape splice. In fact I'd never heard of a tape splice at the time. Needless to say, it failed as soon as I put my weight on it.
Whilst I may well be entitled to a Darwin Award, when we discussed the issue at Bar Herman later that day ALL the other cavers confirmed that they too wouldn't have imagined the insulating tape being a tape splice on new webbing and would have rigged it the same way as me.
When we got back and I told the UK supplier of the issue they were gobsmacked and put procedures in place to ensure it wouldn't happen again. From then on they ensured their webbing stock lengths were actual lengths and not, e.g. 1000m made up of 600m and 400m tape spliced together.
