70% to pass

You are wearing a breathing apparatus inside a tank. How many tugs on the lifeline should you give to indicate that you are advancing?

A 1
B 2
C 3
D 4
AI Explanation

The correct answer is B) 2 tugs on the lifeline. This is the standard signaling procedure for indicating that the diver is advancing while wearing a breathing apparatus inside a tank or other confined space. The 2 tugs on the lifeline clearly communicates to the tender or support personnel that the diver is moving forward, allowing them to monitor the diver's progress and status. The other answer choices are incorrect because 1 tug typically indicates the diver is OK, 3 tugs indicates the diver needs to be pulled out, and 4 tugs is not a standard signal in this context.
