Question 1224 Deck General

The correct answer is C) A red flag by day ONLY. The reason for this is that the regulations set forth by the U.S. Coast Guard require a red flag to be displayed by day when a vessel is engaged in the bunkering or transfer of petroleum products at anchor. This signal alerts other vessels in the vicinity that there are flammable or hazardous operations taking place. At night, no special signal is required, as the bunkering operations should be safely completed before dark. The other options are incorrect because A) displaying both a red flag by day and a red light by night is not the required signal, B) a red light by night only is not the proper signal, and D) no signal is required is incorrect, as the regulations do mandate the use of a red flag during daytime bunkering at anchor.
