This final rule will clarify and simplify OSHA's standards applicable to cranes and derricks in construction by establishing a single set of standards for all construction activities involving cranes and derricks. On August 9, 2010, OSHA issued a Final Rule for Cranes and Derricks in Construction (75 FR 47096), that was originally intended to apply to all crane and derrick use in construction. Rulemaking findings, including the economic analysis, were developed to address all construction work. However, two subsectors of construction work, demolition and underground construction, were exempted from coverage under the new standard, in an effort to ensure that employers involved in those types of work were given sufficient notice to comply with the new rule. These subsectors currently remain covered under the previous rule governing crane and derrick use in construction. This final rule will, therefore, apply the new cranes and derricks rule to both demolition and underground construction work, bringing those subsectors current with the rest of the construction industry. It should be noted that a proposed rule accompanies this direct final rule. Should OSHA receive significant adverse comment on this direct final rule, it will withdraw the direct final rule and proceed with the accompanying proposed rule.
