Question 335 Deck General

The correct answer is A) stop. The signal with the arm extended, palm down, and held rigidly is the standard hand signal to indicate that the crane operator should stop the crane's movement. This signal is part of the established set of hand signals used for communication between the signal person and the crane operator to ensure safe crane operations. The other answer choices are incorrect because they represent different hand signals - B) lower (hand straight down, palm facing down), C) swing (arm extended, hand waving side to side), and D) hoist (arm extended, palm up). Following the proper hand signal protocol is critical to avoid accidents and ensure the crane is operated safely.
