180. The potable water tanks on your vessel were drained for inspection and cleaning. What would you do before refilling with water?

Potable water tanks require disinfection with a chlorine solution after cleaning to prevent contamination. This standard practice ensures water safety for human consumption, as tanks exposed during cleaning can harbor bacteria and other contaminants. Other options, such as using hull paint, ammonia, or skipping disinfection, are unacceptable due to potential contamination and sanitation violations.
