🔍 Key Concepts

• Garbage Record Book entries required under MARPOL and 33 CFR for certain vessels • Standard measurement units used internationally in pollution prevention records • Difference between volume and weight measurements for waste

💭 Think About

• Is garbage typically recorded by how much space it takes up (volume) or how heavy it is (weight) in official logbooks? • When records are used internationally, do regulations usually require metric units, U.S. customary units, or both? • Which option best matches the idea of a consistent, comparable unit for ship‑to‑ship and port‑to‑port reporting?

✅ Before You Answer

• Check what unit of measurement (volume vs weight) MARPOL and U.S. rules specify for the Garbage Record Book. • Verify whether the regulation requires one system of units or dual units to avoid confusion. • Eliminate any options that are not a standardized, regulation‑level unit you’d expect to see in an international convention.
