🔍 Key Concepts

• Potable (drinking) water safety requirements on ships • How evaporators produce distilled water and what can contaminate it • Typical automatic protection/monitoring systems used between production and storage tanks

💭 Think About

• Which option best prevents unsafe water from ever reaching the potable water tank automatically, without needing someone to test every batch first? • Think about what could go wrong if the evaporator salinity rises or there is a machinery fault – which device or arrangement would react to that condition? • Which choices sound more like temporary/portable arrangements versus standard, permanent shipboard installations?

✅ Before You Answer

• Identify which choice includes an automatic safety control linked to an alarm or monitor. • Ask yourself which methods would be impractical to do continuously for all water produced. • Eliminate any option that sounds like it could easily bypass or defeat safety if someone forgot to connect or operate it.
