What document must a crane operator have on hand during operation?

The presence of the operator's license and inspection records is essential during crane operation because these documents demonstrate that the operator is qualified and legally permitted to operate the crane. The operator's license certifies that they have undergone the necessary training and have passed evaluations to ensure they can handle the equipment safely. Inspection records provide verification that the crane has been maintained and is in safe working condition for operation. Together, these documents help ensure compliance with safety regulations and industry standards, which are critical to prevent accidents and ensure the safe operation of the crane.

In contrast, while a job site safety plan, the operator’s manual, and a checklist for materials to be lifted may be important for overall safety and operational guidelines, they do not establish the legality and safety of the crane's operation as directly as the license and inspection records do.
