You are approaching another vessel and see that she has the signal flag "J" hoisted. What should you do?

Correct Answer: Option C — Keep well clear of the vessel because she is on fire and has dangerous cargo on board or she is leaking dangerous cargo.

International Code Flag "J" denotes that the vessel is on fire and carrying dangerous cargo, or is leaking hazardous materials. Approaching vessels must keep well clear due to the extreme explosion, toxicity, or environmental hazards present.
