- C. Notify the Coast Guard and other vessels in the vicinity by radio
- D. Maneuver the vessel to minimize the effect of wind on the fire
Why B is correct
The prescribed firefighting sequence begins with isolating the fire by cutting off its air supply — closing hatches, ports, doors, ventilators, and similar openings — before attacking with an extinguisher. Notifying the Coast Guard and maneuvering the vessel are later steps taken if the fire cannot be controlled. (46 CFR §28.265(d)(9)(i); USCG Boatswain Manual Ch. 6 §6.3)
