What is the purpose of the Smoke Ejection System?

• A. Sweep smoke from pways on DC deck & main deck
• B. Remove smoke by ventilation shafts
• C. Filter air
• D. Generate smoke as a signal

Answer: (A)

The key idea is that the Smoke Ejection System is used to clear smoke from the ship’s passageways so the crew can operate safely during a fire. Its main job is to sweep smoke out of the pways on the damage control deck and the main deck, creating a directed airflow that pulls smoke from compartments toward exhaust routes. By keeping those critical walkways and spaces clear of smoke, visibility improves, fire fighters can locate and reach the fire more easily, and egress routes remain usable. It’s not about filtering air or generating smoke for signaling; and while ventilation shafts are part of how smoke is removed, the essential purpose is to sweep smoke from the key pways to the outside.
