Question 926 Deck Safety

The correct answer is C) Three tugs of the lifeline mean to take up the slack. The Coast Guard's standard operating procedures for self-contained breathing apparatus (SCBA) use in enclosed spaces require the user to tug the lifeline three times to signal the topside crew to take up any slack in the line. This allows the SCBA-equipped personnel to safely return to the surface without becoming entangled or restricted by excess slack in the lifeline. The other answer choices are incorrect because one or two tugs would not be the standard signal, and four tugs could be misinterpreted or confused with a different emergency signal.
