Question 1 of 27070

🔍 Key Concepts

• 46 CFR requirements for fuel oil tank vents on ships of 10,000 GT and above • Purpose of a fixed container/enclosed deck area under fuel oil tank vents (what hazard is it controlling?) • Relationship between vent flow volume and reasonable containment capacity in case of overflow or surge

💭 Think About

• Think about how much fuel could realistically be discharged during a brief overflow or surge at a vent and still be practically contained on deck. • Compare each choice to what seems large enough to control a hazardous spill, but still small enough to be a reasonable permanent structure under every vent. • Ask yourself whether smaller volumes like 5 or 10 gallons would actually be enough on a large, deep‐draft ship during bunkering or ballasting operations.

✅ Before You Answer

• Verify the exact capacity requirement in 46 CFR for fuel oil tank vent containers on ships ≥10,000 gross tons constructed after 30 June 1974. • Confirm that the rule you’re looking at applies to fuel oil tanks, not other tanks (like ballast or cargo). • Double‑check that the capacity is expressed in U.S. gallons with a liter equivalent, just like the answer choices.
