Question 945 Deck Safety

The correct answer is C) 3 tugs of the lifeline mean "Take up slack". This is the correct answer based on the standard signaling procedures used in the US Coast Guard for communicating between a person in the water or a tank and the topside crew. The signal of 3 tugs on the lifeline indicates to the topside crew that they should take up any slack in the lifeline to tighten it, ensuring the safety of the diver or person in the tank. The other answer choices are incorrect because 1 tug typically means "I'm OK", 2 tugs mean "Lower me" or "Raise me", and 4 tugs would be an unusual signal not commonly used for this purpose.
