Question 1 of 27070

Small oil spills on deck can be kept from contaminating the surrounding waters by __________.

🔍 Key Concepts

• Deck scuppers and freeing ports and what they do • How oil on deck normally reaches the sea • Why vents and sounding pipes exist and what happens if you block them

💭 Think About

• Think about the normal path that rainwater or wash water takes to get off the deck and over the side. How could you interrupt that path so spilled oil stays on deck? • Which of these choices would actually be dangerous because it interferes with tank breathing or measuring tank levels, rather than controlling deck drainage? • Ask yourself: which action is specifically meant to stop liquids from draining overboard from the deck itself?

✅ Before You Answer

• Identify which fittings are part of cargo/ballast tank systems (vents, sounding pipes) versus deck drainage systems (scuppers). • Verify which piece of equipment is designed to be temporarily blocked in port to contain spills without creating an unsafe pressure situation. • Eliminate any choice that could cause overpressure or vacuum in a tank or prevent safe sounding/measurement.
