Hi Alex,
You wrote: "I opposed the training scheme proposed for their use in British caves then, because In my experience I found there was a high failure rate even using them for non critical applications, by my employees (professional construction operatives)until they built up a good level of experience in their use . Therefore I didnt think they would be suitable for installation in cave conditions in safety critical situations by non skilled persons after a weekends training course."
There are several thousand ECO Anchors installed in UK caves and we have not had a single catastrophic failure - fact. Anchors that are reported "loose" are inspected and tested and where necessary replaced. The fact that a "loose" anchor is very, very difficult to remove reinforces the strength of the system. Your comment on the quality of the installer misses the point that the correct training is vital, and I believe that the fact that we have not had a catastrophic failure proves the quality of the training.
You wrote: "Although the statistics Glenn can supply me with are no doubt correct, (who compiles them and for what purpose)."
Every ECO Anchor placed in the UK is recorded (including date of installation, who installed it and resin batch number) It's part of the system - which incidental, is the envy of the caving world, something I believe all UK cavers should be proud of. Further, the anchor system is subject to continual and ongoing testing to ensure that it remains absolutely bombroof - and that testing is managed by an industry professional.
You wrote: "If the anchors were not installed correctly at the time, we shall see more episodes of bolt failures and cave closures in the years to come."
The experience to date suggests you are wrong. Rhino Rift was not a catastrophic failure, it was reported loose and the appropriate action taken.
You wrote:"They are excellent anchors, but they have to be installed by skilled personnel and conditions have to be perfect. From my alpine climbing days and foreign caving exploits , I have found the french installations have been most successful, I note you cave in the vercors maybe you could shed some light on the subject"
I must be missing something. You have been critical about the BCA ECO Anchor system which (as I hope I have explained) is a coordinated system with a proven track record, yet you state "french installations have been most successful". THERE IS NO COORDINATED ANCHOR PROGRAMME IN FRANCE - for caving or climbing (NB: I am not including via ferrata here). Anchors in France (either for climbing or caving) are installed by any Tom, Dick or Pierre with no training and to no standard. Yet you are happy with this?
I suspect you are just trolling and this is probably the last time I will post on this thread - life's too short. All the information on the BCA ECO Anchor programme is available on the BCA web site.
Cheers,
Glenn
