Is it true or false that diesel machinery in protected spaces on gasoline boats must automatically shut down upon discharge of a fixed fire extinguishing system?

The statement is true. In accordance with marine safety standards, particularly those outlined by the American Boat and Yacht Council (ABYC), diesel machinery located in protected spaces on gasoline-fueled boats must be designed to automatically shut down if a fixed fire extinguishing system is discharged in those spaces. This requirement helps prevent the potential for an explosion or additional fire hazards, as the presence of gasoline vapors may pose a serious risk when the fire extinguishing agent is introduced. The automatic shutdown of the machinery ensures that any ignition sources are eliminated, enhancing the overall safety of the vessel. This protocol is part of broader safety measures mandated to protect both passengers and the integrity of the boat.
