According to the Pollution Prevention Regulations (33 CFR), no person may use a connection for oil transfer operations unless it is a bolted or full threaded connection, or __________.
• 33 CFR oil transfer connection requirements for pollution prevention • Differences between permanent mechanical joints (bolted/threaded) vs. more temporary methods (clamps, compression fittings) • Who typically has authority to approve specialized couplings for oil transfer under federal regulations
• Look at which option best matches the same level of security and leak prevention as a bolted or fully threaded connection. • Ask yourself: Which choice reflects a formal standard or approval process you would expect to be written directly into a federal regulation? • Consider which options sound more like informal practices versus something you would see specified word‑for‑word in 33 CFR.
• Verify which option is most likely to be explicitly named in 33 CFR text, not just a general description. • Eliminate any option that would depend only on hose size instead of the actual security of the connection. • Be sure the remaining option provides a connection that is at least as reliable against leaks and disconnects as bolted or fully threaded connections.
