The BCA Anchor Working Group have recently approved and published a new version of the Pre-Use Inspection of Resin Bonded Anchors document.
This provides guidance on how to identify an approved BCA anchor, how to check anchors prior to use and what you should do if you spot a defective anchor.
Please find this available to download below.
BCA encourages all cavers to read this document, especially those that rig or use resin bonded anchors underground.
