🔍 Key Concepts

• 46 CFR Part 154 – Safety Standards for Self-Propelled Vessels Carrying Bulk Liquefied Gases • Role of the Commandant vs. local Officer in Charge, Marine Inspection (OCMI) • Difference between a regulatory approval authority and a classification society

💭 Think About

• Ask yourself: when a cargo is not listed in a regulatory table, does that usually call for a higher-level, centralized approval or a local field approval? • Consider which of the options actually has legal authority to approve carriage of a specific hazardous cargo under federal regulations, not just inspect or classify the ship. • Think about whether a private organization or the vessel owner can legally authorize carriage of an unlisted dangerous cargo under U.S. regulations.

✅ Before You Answer

• Look in 46 CFR Part 154, Subpart B (or introductory sections) for who grants special or specific approvals for liquefied gas cargoes. • Verify which of the choices is a USCG headquarters-level authority versus a local field office or private entity. • Confirm that the approving party must have explicit regulatory authority over hazardous cargoes, not just inspection or classification duties.
