🔍 Key Concepts

• Purpose and typical contents of a contaminated steam generator on a ship • Which shipboard liquids are considered dirty / contaminated and still commonly collected in a tank • Why certain systems (like sanitary, cooling, or fuel heating systems) are usually kept separate from contaminated steam systems

💭 Think About

• Ask yourself: Which of these liquids is normally treated as the dirtiest mixture on board and collected from many spaces? • Which one is commonly pumped into a holding tank, often with oily residues and detergents? • Which options are usually kept as clean or controlled systems, and therefore unlikely to be fed to a unit labeled contaminated?

✅ Before You Answer

• Identify which choice represents a mixture of oily/dirty drainage from machinery spaces. • Eliminate any option that is normally maintained as potable/clean or treated separately for health reasons. • Think about what type of waste liquid a ship would want to flash into vapor to reclaim some heat rather than just dump directly.
