What action is prohibited while using an aerial lift?

While using an aerial lift, moving the aerial lift with the boom elevated is prohibited due to safety concerns. This action poses a significant risk for both the operator and those working nearby. When the boom is raised, the stability of the lift can be compromised, increasing the chance of tipping over or losing load control. It is crucial to ensure that the lift is stable and grounded before moving it, especially if the boom is in an elevated position.

Moreover, the other options listed are related to safety practices that ensure proper use of the equipment. Wearing a body belt is a safety measure that can help secure the operator. Performing a pre-lift meeting is an important step in discussing safety protocols and roles, and testing the controls before use ensures that the equipment is functioning correctly, thereby promoting safety. These practices are essential in preventing accidents and ensuring that the aerial lift is operated within safe parameters.
