Question 451 Deck General

The correct answer is B) Master. The master of the vessel is responsible for ensuring that the emergency lighting and power systems on cargo vessels are operated at least weekly. This is a requirement under U.S. Coast Guard regulations to ensure the proper functioning of these critical systems in the event of an emergency. The master, as the person in charge of the overall safety and operation of the vessel, is the one who must oversee this weekly test and maintenance. The other options, while potentially involved in the operation and maintenance of the emergency systems, are not the ones ultimately responsible for ensuring the weekly testing is done. The deck officer, engineering officer, or chief engineer may carry out the actual testing, but the master is the one who must ensure it is completed.
