70% to pass

How should you signal the crane operator to use the whip line?

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

The correct answer is C) First tap your elbow with one hand, and then proceed to use regular signals. This is the correct answer because the standard hand signals for crane operations require the crane operator to first be given a signal to indicate that the whip line (the small line used to control the movement of the load) is to be used. Tapping the elbow is the established signal to indicate that the whip line should be used, before proceeding with the regular hand signals to direct the movement of the load. The other options are incorrect because they do not follow the established crane signal protocols. Tapping the head (A) or using a thumb-up motion (B) are not the recognized signals for using the whip line. Option D describes a generic motion signal but does not specify the initial elbow tap required to indicate the use of the whip line.
