Regardless of the type of work producers do, OSHA requires them to use only "competent" crane operators. It hasn't always been easy to determine whether operators have the knowledge and skills necessary to be deemed competent--that is, until recently. The National Commission for the Certification of Crane Operators (CCO), an independent, not-for-profit organization, was set up to establish and administer a nationwide program to certify crane operators. An examination of crane operators contains three parts: a written test, a practical test and a medical evaluation conducted through a third-party, independent, standardized program, independent of training. The program is recognized by credentialing organizations and federal and state governments and fits the wide variety of crane uses.
