🔍 Key Concepts

• Watertight integrity and why openings in tanks or compartments are critical in an emergency • How flooding water actually travels through a vessel once initial damage occurs • Why pre‑damage preparation is more effective than reaction measures like pumping

💭 Think About

• If a compartment is holed, how could water spread to other spaces through existing fittings or openings? • Which choice reduces the number of paths for water to move through the structure before an emergency happens? • Which option would be practical and safe to maintain for long periods in normal operations?

✅ Before You Answer

• Identify which option directly improves watertight integrity of tanks/spaces rather than just monitoring or reacting to flooding • Consider whether running equipment like bilge pumps continuously is standard safe practice or could be problematic • Ask which measure would most effectively slow or limit progressive flooding if structural damage occurs
