OSHA also mandates that the tag has to be attached with a non reusable "thing?" that is capable of withistanding 50 pounds of force. Sorry for the thing word, having a brain fart right now. The reson is do that it is harder for an unathorized person to take off the tag. Basically they mean a 1/4" wire tie. If the tag is put on with some string, or wire, it is easy for somone to undo the knot and remove the tag.

I received a catalog from a sign company that was selling the tags you pictured. However they had wire in the eye for people to use when attaching the tag. I e-mailed them about it and said they were selling something that is non-compliant. In their return e-mail they blew me off.
