As seen in illustration D035SA below, when the remote push button located in the wheelhouse, starboard side, frame 122, is actuated, what is the result?

Correct Answer: Option C — Ventilation ducts are secured

Wheelhouse remote actuation stations located at frame 122 control emergency ventilation shutdown devices to isolate machinery spaces during a major fire. Securing forced air prevents oxygen replenishment and restricts smoke propagation throughout accommodation and engineering zones.
