8 24 iv o o FOREWORD This american national Standard, Safety Standard for Cableways, Cranes , Derricks, Hoists, Hooks, Jacks, and Slings, has been developed under the procedures accredited by the american national Standards Institute (ANSI, formerly the United States of America Standards Institute). This Standard had its beginning in December 1916 when a Code of Safety Standards for Cranes , prepared by an asme Committee on the Protection of Industrial Workers, was presented to the annual meeting of the asme . Meetings and discussions regarding safety on Cranes , derricks, and hoists were held from 1920 to 1925, involving the asme Safety Code Correlating Committee, the Association of Iron and Steel Electrical Engineers, the american Museum of Safety, the american Engineering Standards Committee (later changed to american Standards Association and subsequently to the USA Standards Institute), the Department of Labor -State of New Jersey, tlle Department of Labor and Industry -State of Pennsylvania, and the Locomotive Crane Manufacturers Association.

9 On June 11, 1925, the american Engineering Standards Committee approved tlle asme Safety Code Correlating Committee's recommendation and authorized the project with the Depart-ment of the Navy, Bureau of Yards and Docks, and asme as sponsors. In March 1926, invitations were issued to 50 organizations to appoint representatives to a Sectional Committee. The call for organization of this Sectional Committee was sent out October 2, 1926, and tlle Committee organized November 4, 1926, with 57 members representing 29 national organizations. The Safety Code for Cranes , Derricks, and Hoists, ASA , was created from tlle eight-page document referred to in tlle first paragraph.

10 This document was reaffirmed in 1952 and widely accepted as a safety standard. Due to changes in design, advancement in techniques, and general interest of labor and industry in safety, the Sectional Committee, under the joint sponsorship of asme and the Naval Facilities Engineering Command, Department of the Navy, was reorganized as an american national Standards Committee on January 31,1962, witl139 members representing 27 national organiza-tions. The format of tlle previous code was changed so tllat separate volumes (each complete as to construction and installation; inspection, testing, and maintenance; and operation) would cover the different types of equipment included in the scope of B30.
