FOREWORD This American National Standard, Safety Standard for Cableways, Granes, Derricks, Hoists, Hooks, Jacks, and Slings, has been developed under the procedures accredited by the American National Standards Institute (ANSI). This Standard had its beginning in December 1916 when an eight-page Code of Safety Standards for Granes, prepared by an ASME Gommittee on the Protection of Industrial Workers, was presented at the annual meeting of ASME. Meetings and discussions regarding safety on cranes, derricks, and hoists were held from 1920 to 1925 involving the ASME Safety Gode Gorrelating Gommittee, the Association of Iron and Steel Electrical Engineers, the American Museum of Safety, the American Engineering Standards Gommittee (AESG) [later changed to American Standards Association (ASA), then to the United States of America Standards Institute (USASI), and finally to ANSI], Department of Labor — State of New Jersey, Department of Labor and Industry — State of Pennsylvania, and the Locomotive Grane Manufacturers Association. On June 11,1925, AESG approved the ASME Safety Gode Gorrelating Gommittee's recommendation and authorized the project w i t h the U.S. Department 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 Gommittee. The cali for organization of this Sectional Gommittee was sent out October 2, 1926, and the committee organized November 4, 1926, with 57 members representing 29 national organizations. Gommencing June 1, 1927, and using the eight-page code published by ASME in 1916 as a basis, the Sectional Gommittee developed the Safety Gode for Granes, Derricks, and Hoists. The early drafts of this safety code included requirements for jacks but, due to inputs and comments on those drafts, the Sectional Gommittee decided in 1938 to make the requirements for jacks a sepárate code. In January 1943, ASA B30.2-1943 was published addressing a multitude of equipment types, and in August 1943, ASA B30.1-1943 was published just addressing jacks. Both documents were reaffirmed in 1952 and widely accepted as safety standards. Due to changes in design, advancement in techniques, and general interest of labor and industry in safety, the Sectional Gommittee, under the joint sponsorship of ASME and the Bureau of Yards and Docks (now the Naval Facilities Engineering Gommand), was reorganized on January 31,1962, with 39 members representing 27 national organizations. The new committee changed the format of ASA B30.2-1943 so that the multitude of equipment types it addressed could be published in sepárate volumes that could completely cover the construction, installation, inspection, testing, maintenance, and operation of each type of equipment that was included in the scope of ASA B30.2. This format change resulted in the initial publication of B30.3, B30.5, B30.6, B30.il, and B30.16 being designated as revisions of B30.2 with the remainder of the B30 volumes being published as totally new volumes. ASA changed its ñame to USASI in 1966 and ANSI in 1969, which resulted in B30 volumes from 1943 to 1968 being designated as ASA B30, USAS B30, or ANSI B30, depending on their date of publication. In 1982, the Committee was reorganized as an Accredited Organization Gommittee, operating under procedures developed by ASME and accredited by ANSI. This Standard presents a coordinated set of rules that may serve as a guide to government and other regulatory bodies and municipal authorities responsible for the guarding and inspection of the equipment falling within its scope. The suggestions leading to accident prevention are given both as mandatory and advisory provisions; compliance with both types may be required by employers of their employees. In case of practical difficulties, new developments, or unnecessary hardship, the administrative or regulatory authority may grant variances from the literal requirements or permit the use of other devices or methods but only when it is clearly evident that an equivalent degree of protection is thereby secured. To secure uniform application and interpretation of this Standard, administrative or regulatory authorities are urged to consult the B30 Gommittee, in accordance with the format described in Section IX of the Introduction, before rendering decisions on disputed points. Safety codes and standards are intended to enhance public safety. Revisions result from committee consideration of factors such as technological advances, new data, and changing environmental and industry needs. Revisions do not imply that previous editions were inadequate. v

The 2009 edition of B30.10 was rewritten entirely to improve the clarity of the Standard. This 2014 edition incorporates many global B30 changes, including the addition of personnel competence and translation requirements, as well as other revisions made throughout the document. This edition of the B30.10 Volume was approved by the B30 Committee and ASME and was approved by ANSI and designated as an American National Standard on May 23, 2014.

ADDITIONAL 6UIDANCE

The equipment covered b y the B30 Standard is subject to hazards that cannot be abated by mechanical means, but only by the exercise of intelligence, care, and comm o n sense. I t is therefore essential to have personnel involved i n the use and operation of equipment w h o are competent, careful, physically and mentally qualified, and trained i n the proper operation of the equipment and the h a n d l i n g of loads. Serious hazards include, but are not l i m i t e d to, improper or inadequate maintenance, overloading, d r o p p i n g or slipping of the load, obstructing the free passage of the load, and using equipment for a purpose for w h i c h i t was not intended or designed. The B30 Standard Committee f u l l y realizes the i m p o r tance of proper design factors, mínimum or máximum dimensions, and other l i m i t i n g criteria of w i r e rope or chain and their fastenings, sheaves, sprockets, d r u m s .
