18、s of America Standards Institute). ThisStandard had its beginning in December 1916 when an eight-page Code of Safety Standards forCranes, prepared by an ASME Committee on the Protection of Industrial Workers, was presentedto the annual meeting of the ASME.Meetings and discussions regarding safety on
19、 cranes, derricks, and hoists were held from 1920to 1925, involving: the ASME Safety Code Correlating Committee, the Association of Iron andSteel Electrical Engineers, the American Museum of Safety, the American Engineering StandardsCommittee (later changed to American Standards Association and subs
20、equently to the USAStandards Institute), Department of Labor State of New Jersey, Department of Labor andIndustry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. OnJune 11, 1925, the American Engineering Standards Committee approved the ASME Safety CodeCorrelating Committe
21、es recommendation and authorized the project, with the U.S. Departmentof the Navy, Bureau of Yards and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint representatives to aSectional Committee. The call for organization of this Sectional Committee was
22、sent out October2,1926,andthecommitteeorganizedNovember4,1926,with57membersrepresenting29nationalorganizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, was createdfrom the eight-page document referred to in the first paragraph. This document was reaffirmedin 1952 and widely
23、 accepted as a safety standard.Duetochangesindesign,advancementintechniques,andgeneralinterestoflaborandindustryin safety, the Sectional Committee, under the joint sponsorship of ASME and the Naval FacilitiesEngineering Command, U.S. Department of the Navy, was reorganized as an American NationalSta
24、ndards Committee on January 31, 1962, with 39 members representing 27 nationalorganizations.The format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, testing, and maintenance; and operation) will cover thedifferent types of
25、equipment included in the scope of B30.In 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by the ASME and accredited by the American National StandardsInstitute.This Standard presents a coordinated set of rules that may serve as a guid
26、e to governmentandotherregulatorybodiesandmunicipalauthoritiesresponsiblefortheguardingandinspectionof the equipment falling within its scope. The suggestions leading to accident prevention aregiven both as mandatory and advisory provisions; compliance with both types may be requiredby employers of
27、their employees.In case of practical difficulties, new developments, or unnecessary hardship, the administrativeor regulatory authority may grant variances from the literal requirements or permit the use ofother devices or methods, but only when it is clearly evident that an equivalent degree ofprot
28、ection is thereby secured. To secure uniform application and interpretation of this Standard,administrative or regulatory authorities are urged to consult the B30 Committee, in accordancewith the format described in Section IX, before rendering decisions on disputed points.This Volume of the Standar
29、d, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an American National Standard on July 19, 2007.Safetycodesandstandardsareintendedtoenhancepublicsafety.Revisionsresultfromcommit-teeconsiderationoffactorssuchastechnologicaladvances,newdata,andchangingenvir
