What is the hand signal for "Boom up" in crane operation?

Arm out
Finger down counter clockwise
Thumbs in
Thumb up

The correct answer is: Arm out

The hand signal for "Boom up" in crane operation is typically represented by extending one arm straight out to the side, which clearly indicates to the operator that the boom should be elevated. This signal is intuitive, as it visually represents the action of lifting the boom upward. The other options use different gestures that don't convey the specific action of moving the boom up. The correct gesture is established in signaling standards in the construction and crane-operating industries to ensure that communication between the ground crew and the crane operator is both clear and effective for safe operations. Thus, extending the arm out is the recognized and appropriate signal for this action.
