🔍 Key Concepts

• 46 CFR Subchapter T requirements for fuel tanks on small passenger vessels • Purpose of baffle plates and when they are required in fuel tanks • Why electrical bonding/grounding is important for gasoline systems on passenger vessels

💭 Think About

• For each option (A, B, C), ask yourself: is this an explicit requirement in 46 CFR for gasoline tanks on small passenger vessels, or does it apply to some other type of tank/vessel? • Think about why gasoline is especially hazardous compared to diesel, and how that affects design requirements for tank construction, internal structure, and electrical safety. • Consider whether any one of the statements (A, B, or C) is not a universal requirement for all such tanks; if even one is not always required, what does that imply about choice D?

✅ Before You Answer

• Verify in 46 CFR 182 (Construction and Arrangement) the specific wording on gasoline tank top edges and whether flanged-up tops are prohibited or required. • Check the exact dimension/condition in CFR for when baffle plates are required (is it strictly 30 inches in any horizontal dimension, or worded differently?). • Confirm which gasoline tanks on small passenger vessels must be electrically bonded to a common ground, and whether this applies to all gasoline tanks or only certain installations.
