70% to pass

Prior to handling Class 1 explosive materials, which signal(s) is/are required to be displayed by the vessel?

A an announcement on VHF channel 16 every hour
B the Bravo flag and signs posted prohibiting smoking
C an all-round flashing blue light
D the Bravo flag and a flashing red all-round light
AI Explanation

The correct answer is B) the Bravo flag and signs posted prohibiting smoking. This is the correct answer because the Bravo flag is the international signal used to indicate that a vessel is carrying dangerous cargo, including Class 1 explosives. The Bravo flag, along with posted signs prohibiting smoking, are the required signals to be displayed by the vessel when handling Class 1 explosive materials. The other answer choices are incorrect because they do not align with the regulatory requirements for signaling the presence of Class 1 explosives. Announcements on VHF channel 16, a flashing blue light, or a flashing red light are not the proper signals for this situation.
