You are in a channel in U.S. waters near an industrial plant with a load/discharge facility for barges. You hear a siren being sounded at the facility. What does this indicate?

Correct Answer: Option C — There is danger at the facility due to a fire or cargo release.

Under coastal industrial facility safety regulations, sounding a continuous siren at a waterfront transfer terminal signals an active emergency situation, specifically warning vessels in the channel of an immediate danger due to a fire or cargo release.
