70% to pass

The signal man assisting the crane operator has his arm extended downwards, forefinger pointing down, and moves his hand in small horizontal circles. This is the signal to _______________.

A swing

B lower

C hoist

D extend

AI Explanation

The correct answer is B) lower. The signal of an extended arm with the forefinger pointing down and making small horizontal circles indicates that the crane operator should lower the load. This hand signal is part of the standard signaling system used in crane operations to communicate between the crane operator and the signal person, as specified in regulations and industry standards for crane safety. The other answer choices are incorrect because they do not match the described hand signal. Swinging (A), hoisting (C), and extending (D) the load would each have different corresponding hand signals.
