Question 943 Deck Safety

The correct answer is B) 2 tugs on the lifeline indicate the man should advance. The reasoning behind this is that in a confined space entry, the standard communication protocol is for the person inside the compartment to tug on the lifeline twice to signal that they are ready to advance further. This allows the tender outside to monitor the progress and safety of the person entering the compartment using the breathing apparatus. Other tug signals, such as 1 tug or 3-4 tugs, would indicate different meanings or requests, which would not be the correct response for advancing into the compartment.
