Question 991 Deck Safety

The correct answer is C) 32. On the vessel's fire control plan, the symbol 32 represents fire dampers, which help control the spread of fire by regulating the airflow and containing the fire. Fire dampers are an important part of the vessel's fire control system, as they can isolate compartments and prevent the fire from spreading throughout the ship. The other answer choices do not represent symbols that directly control the spread of fire. Symbol 33 may represent other fire-fighting equipment, symbol 34 could be a fire alarm or detection device, and symbol 68 likely indicates something unrelated to fire control.
