Question 3764 Deck General

The correct answer is B) week. The Code of Federal Regulations (CFR) requires that on offshore drilling units, emergency lighting and each emergency power system must be tested at least once a week. This is specified in 46 CFR 111.75-15, which states that "each emergency power system must be tested weekly." The other answer choices are incorrect because testing the emergency lighting and power systems less frequently (once a day, month, or year) would not meet the regulatory requirements for ensuring the reliability of these critical safety systems on offshore drilling units.
