🔍 Key Concepts

• 46 CFR requirements for fuel oil service systems near burners • The purpose of protection around flanged joints and fittings in case of a spray or leak • How regulations try to prevent fuel from spraying on hot surfaces and starting a fire

💭 Think About

• Ask yourself which option best prevents a spray of fuel from reaching hot burner parts if a joint starts leaking. • Consider which choice is specifically directed at bolted flanged joints in way of burners, instead of being a general good‑practice piping requirement. • Think about what physical barrier or arrangement the CFR would require so that a failure at a flange does not immediately become a fire hazard.

✅ Before You Answer

• Verify in 46 CFR Part 56/Part 62 (as applicable) what is explicitly required for fuel oil service piping near burners, not just recommended practice. • Check which answer choice mentions something that would redirect or shield leaking oil at bolted flanges, rather than simply trying to make the joints tighter. • Confirm that the requirement applies only to bolted flanged joints in the vicinity of burners, not necessarily to every joint in the entire fuel system.
