ANSI Z359-2007 is the Fall Protection Code
It consists of 8 separate ANSI documents available for purchase and download at ANSI.org and ASSE.org.
ANSI standards are voluntary, and they do not carry the enforcement burden of federal OSHA standards. They do, however, contain up-to-date methods for complying with OSHA standards. Employers who are in compliance with ANSI standards, and have documented evidence to back it up, are virtually assured of meeting or exceeding all OSHA mandatory provisions.
