How should you signal the crane operator to use the main hoist?

A Extend arm with the thumb pointing up and flex the fingers in and out for as long as the load movement is desired.
B First tap your elbow with one hand, and then proceed to use regular signals.
C Use one hand to give any motion signal, and place the other hand motionless in front of the hand giving the motion signal.
D First tap the top of your head with your fist, and then proceed to use regular signals.
AI Explanation

The correct answer is D) First tap the top of your head with your fist, and then proceed to use regular signals. This is the correct answer because the regulations for crane signal communication require the crane operator to be alerted before regular signals are used. Tapping the top of the head with a fist is the established signal to get the crane operator's attention before proceeding with the desired motion signal. The other options are incorrect because they do not follow the established protocol of first alerting the crane operator before giving the motion signal. Option A, B, and C do not include the required attention-getting signal.
