Which of the following describes the OSHA standard method hand signals to lower the block?

The correct description of the OSHA standard method hand signals to lower the block is when the arm and index finger are pointing down, and the hand and finger make small circles. This specific signal effectively communicates to the operator that the load should be lowered.

Using the index finger pointing down visually indicates the downward direction of the load, while the circular motion serves as a clear cue to ensure the operator understands the continuous action that is required — that is, to lower the block smoothly and steadily. This method helps maintain safety on the worksite by providing a clear and consistent signal that eliminates ambiguity.

Other hand signals may represent different actions, and clarity in communication is essential in crane operations to prevent accidents and ensure precise control of loads.
