The mist system draws its water from which source?

• A. Potable water
• B. Seawater
• C. Graywater
• D. Reclaimed water

Answer: (A)

The mist system uses clean, treated water from the ship’s potable water system. This ensures the water is free of salts, minerals, and contaminants that could clog fine mist nozzles, foul pumps, or cause corrosion. Graywater and reclaimed water contain contaminants and are not suitable for high-pressure mist systems, while seawater introduces salt and mineral buildup that would damage equipment. Using potable water, which is already treated and disinfected, keeps the system reliable and safe for firefighting while protecting the rest of the drinking-water network with proper backflow protection.
