Question 1 of 27070

Coast Guard Regulations (46 CFR) permit drain valves in the machinery space for removing water and impurities from diesel engine fuel systems. Those valves must be __________.

🔍 Key Concepts

• 46 CFR requirements for fuel system drain and sampling valves in machinery spaces • How leakage and fire hazards are controlled on diesel fuel systems • The difference between valves that "prevent leakage" by design vs. by an added securing device

💭 Think About

• Ask yourself: in an engine room, what is the Coast Guard MOST worried about when allowing a drain valve on a fuel line or tank? • Consider which option specifically addresses securing the valve outlet itself, not just the internal valve mechanism. • Think about what simple, reliable measure you could add to a drain point so that even if the valve is bumped or slightly open, fuel will not freely escape.

✅ Before You Answer

• Verify in 46 CFR that the rule speaks about drain cocks/valves on fuel systems and any required means of closure or security. • Check which options deal with the outlet end of the drain versus the internal operation of the valve alone. • Confirm which choice reflects a secondary, positive means to prevent fuel leakage from the drain connection.
