Prior to burning or welding on a fuel tank on a MODU, regulations require that an inspection be made. An entry in the unofficial logbook is required if this inspection is made by __________.

Correct Answer: Option C — the Master or person in charge of the MODU

46 CFR 109.211 requires that when the Master or person-in-charge performs the inspection prior to hot work on a fuel tank, they must document this action in the official or unofficial logbook. This provides a formal record of safety precautions taken to prevent fire or explosion.
