Question 361 Deck General

The correct answer is D) use the main hoist. The signal of tapping the top of the head with the fist is the standard signal to indicate that the main hoist should be used. This signal is part of the standard set of hand signals used in crane and rigging operations to communicate between the signal person and the crane operator. By tapping the head first, the signal person is clarifying that the subsequent hand signals will be directing the use of the main hoist, rather than any auxiliary or supplementary rigging lines. The other answer choices are incorrect because they do not correspond to the specific head-tapping signal. Using the whip line, auxiliary line, or proceeding slowly would require different hand signal sequences.
