Question 1 of 27070

Q

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

🔍 Key Concepts

• 46 CFR requirements for exhaust systems on inspected vessels • Protection of persons in accommodation/berthing spaces from heat and gases • Difference between discharge location vs. insulation and shielding requirements

💭 Think About

• Ask yourself: which option is directly concerned with protecting people who might be sleeping or living near a hot exhaust pipe? • Consider whether the regulation is mainly about where the pipe ends, or how it is safely routed through spaces on board. • Think about what could happen if a dry exhaust pipe runs through a berthing space with no special protection—what hazard is the regulation trying to prevent?

✅ Before You Answer

• Verify in 46 CFR whether dry exhaust requirements focus on insulation/lagging when passing near combustible materials or berthing spaces. • Check if there is any explicit requirement that a horizontal dry exhaust must terminate above the deepest load line, or if that applies more to discharges/outlets in general. • Confirm whether the regulation actually prohibits penetration of the engine-room casing, or instead allows it under certain protective conditions.
