 The first edition of the NFPA 1983 was originally intended to give requirements only for ropes used by the fire service.  However, it quickly became apparent that requirements for all other rigging components - hardware, software, and harnesses - would also be needed.  As NFPA 1983 has continued to undergo updates and revisions, the standard has grown to encompass a much broader range of equipment, now stipulating requirements for design, construction, and performance.
