🔍 Key Concepts

• 46 CFR requirements for cargo tank overfill protection on tank vessels • Purpose of high level and overfill alarms during cargo loading • Regulatory idea of testing "close in time" to a cargo transfer but not so early that conditions can change

💭 Think About

• Look at how the regulations phrase the timing: do they say simply "before loading" or do they give a specific time window? • Think about why the Coast Guard wants a limit on how many hours before loading you can test these alarms. • Compare the answer choices and ask: which one both guarantees the alarm works for this specific loading and prevents a test from being done days ahead of time?

✅ Before You Answer

• Check 46 CFR Part 39 (cargo tank overfill protection) to see the exact wording on when tests must be done. • Confirm whether the regulation specifies a number of hours before loading rather than a vague "prior to loading." • Make sure the option you choose reflects a maximum time before loading (a latest-allowable test time), not just a routine schedule like weekly.
