Question 1 of 29218

Q

Coast Guard Regulations (46 CFR) require a horizontal dry exhaust pipe from a diesel engine must __________.

🔍 Key Concepts

• 46 CFR requirements for diesel engine exhaust systems • Safety concerns with horizontal dry exhaust pipes on small passenger and inspected vessels • Protection of openings from boarding seas and water entry

💭 Think About

• Ask yourself which option deals with the primary hazard specific to a horizontal, dry exhaust pipe rather than exhaust pipes in general. • Consider which choice addresses something that must be true at all times underway, not just in special locations like berthing spaces or engine casings. • Think about what might happen if seawater or waves reached the open end of a horizontal dry exhaust — which requirement directly reduces that risk?

✅ Before You Answer

• Verify in 46 CFR Part 182 or related subparts on machinery and electrical installations what is explicitly required for diesel exhaust arrangements. • Check which options are general good practice versus a specific regulatory requirement tied to the exhaust’s orientation and type. • Confirm which choice directly mentions preventing water/seas entering the exhaust system, which could back-flood the engine.
