Reference Answer
(a) Measures to stop exhaust gas leakage in the Engine room:
Ensure that all exhaust manifolds and pipes are properly sealed to prevent gas leakage. The exhaust outlet should be fully enclosed and directed to the funnel, minimising any escape of exhaust gases into the engine room.
Flexible expansion bellows should be fitted to accommodate thermal expansion in the exhaust system. These bellows prevent cracks and leaks that could arise from the expansion and contraction of exhaust pipes due to temperature changes.
Each exhaust pipe from the engine, boiler, and incinerator has a drain. This is to remove water/condensate, preventing corrosion that could lead to exhaust leaks.
