Hi My company has a large number (2000+) of karabiners in circulationamongst a large workfoce, some of which will be used daily and some never, with most in between. All our harnesses, lanyards etc are serial numbered at manufacture - karabiners aren't. Inspection regimes are in place for all the webbing items - OK so far. Our problem is inspection of the karabiner and how to prove/record it, since they are all identical. I have spoken to, and checked websites of, several major manufacturers - all say they need to be inspected but don't suggest how the karabiner should be identified so that the inspection can be recorded. We have considered loose key tags, but these could easily move between otherwise identical karabiners. Marker pen will rub off. Stamping is not allowed - could damage the item. Does anybody have any ideas/systems already in place to allow foolproof traceability? thanks!

Have a look at these: http://www.ccl-label.com...guage/en-US/Default.aspx I have no connection to this company, other than as a customer. Andy

How many do you have that are permanently affixed to a lanyard? The companies i deal with have these and inspect the karabiners when they inspect the harness & lanyard.
