## Abstract

On August 9, 2010, OSHA issued a final standard updating the requirements for cranes and derricks used in construction work. For most construction work, the final rule replaced a prior cranes and derricks standard. However, the prior standard continues to apply to demolition and underground construction work. Through this direct final rule, OSHA is applying the updated requirements to that work. With this direct final rule, OSHA also is correcting inadvertent errors made to the demolition and underground construction standards when it issued the final rule for cranes and derricks in construction.
