What is the correct procedure for operating lower controls of an aerial lift?

The reason why permission from the person in the lift is necessary, except in emergencies, is grounded in safety protocols. When operating lower controls of an aerial lift, the operator must ensure that the person inside the lift is aware and consenting to the actions being taken. This process helps to prevent accidents, such as unintended movements that could lead to injury or destabilization of the lift.

Also, communication between the ground operator and the person in the lift is vital to ensure a coordinated operation and that both individuals are aware of their surroundings. The emphasis on requiring permission underscores the responsibility both parties have in maintaining a safe working environment. In emergency situations, the standard may vary to allow immediate action to prevent serious harm, hence the distinction made for such scenarios.

This careful consideration of safety and communication is why option B is the appropriate and correct procedure when operating lower controls of an aerial lift.
