In 1982. and Hoists. compliance with both types may be required by employers of their employees. and the committee was organized on November 4. the administrative or regulatory authority may grant variances from the literal requirements or permit the use of other devices or methods. The call for organization of this Sectional Committee was sent out on October 2.16 being designated as Revisions of B30. the Committee was reorganized as an Accredited Organization Committee. the Association of Iron and Steel Electrical Engineers. the Sectional Committee developed the Safety Code for Cranes.S. 1926. but only when it is clearly evident that an equivalent degree of protection is thereby secured. On June 11. the Sectional Committee. the Sectional Committee decided in 1938 to make the requirements for jacks a separate code. in accordance with the format described in the introduction of Section IX. Jacks. administrative or regulatory authorities are urged to consult the B30 Committee. 1962. This Standard presents a coordi- nated 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. 26-2004. Detachable Load-Indicating Devices — Selection. The second edition. Safety codes and standards are intended to enhance public safety. Revisions result from commit- tee consideration of factors such as technological advances. and changing environmental and industry needs. The first edition of this Volume was B30. was approved by ANSI and designated as an American National Standard on August 6. published on May 20. added Chapter 26-6. This 2015 Edition incorporates many global B30 changes.26-2010. and references. vi . addition of general information paragraphs in the inspection Sections. 2015. translations. and Maintenance. including addition of Sections on personnel competence. which was approved by the B30 Committee and by ASME. 2010. and other revisions.
