Question 449 Deck General

The correct answer is B) in each week. The reasoning for this is that the regulations for cargo vessels, as outlined in Title 46 of the Code of Federal Regulations (CFR), Section 111.75-15, state that the emergency lighting and power systems on these vessels must be tested at least once a week. This is to ensure the proper functioning of these critical safety systems in the event of an emergency. The other options are incorrect because they do not align with the weekly testing requirement specified in the regulations. Testing the systems monthly, every 6 months, or every 12 months would not be frequent enough to meet the regulatory standards.
