They are probably referring to Appendix B from the Bank Protection Act, before it underwent a rewrite, which became effective 5/1/91. The old BPA had Appendix A, "Minimum Standards for Security Devices", and Appendix B, which was "Proper Employee Conduct During and After a Robbery". Both Appendix were removed from the revised BPA, which was condensed significantly in 1991. I would be happy to fax you Ap. B if you will give me your fax #.
