Elevator Mechanic Practice Exam

The correct choice states that tie-offs are first required at 12 feet and no more than 26 feet apart vertically. In scaffolding safety regulations, establishing tie-offs is essential for ensuring stability and preventing falls. The requirement to have the first tie-off at 12 feet is derived from commonly accepted safety practices, which often dictate that structures exceeding a certain height must be secured for safety. Furthermore, the specification of a maximum spacing of 26 feet between vertical tie-offs reflects safety guidelines that aim to enhance the structural integrity of the scaffolding system. It is crucial for maintaining a secure environment for workers, as increasing distance between tie-offs could compromise safety. In contrast, other options may not align with the required safety standards or best practices typically endorsed in the industry, such as spacing or the initial height for tie-offs. Thus, the selected choice adheres to established scaffolding safety protocols.
