Active desmoking is used to achieve which objective?

• A. remove smoke and heat from the smoke control zone prior to extinguishing the fire
• B. cool the hull
• C. seal all openings to prevent smoke
• D. vent exhaust to the sea

Answer: (A)

Active desmoking focuses on making the space safe for firefighting by removing the smoky, hot air from the accessible area before or while you attack the fire. On a ship, smoke controls the conditions in the space, so pushing out the smoke and reducing the heat helps you see, move, and apply extinguishing agents more effectively. Ventilation and exhaust to the sea are the means to accomplish this, but the core objective is to clear the smoke and heat from the smoke control zone so you can operate safely and efficiently. Cooling the hull, sealing openings, or merely venting without removing the smoke don’t address the immediate need to improve interior conditions for fire attack.
