AIGF Exit Exam • Set 7 Question 17 of 30

In power generation including propulsion and other energy converters, the strength to withstand the worst case over pressure due to ignited gas leaks to contain an ignitable gas and air mixture are fitted with ______________

✓

Direct Answer

Option D: Pressure relief systems

Pressure relief systems are critical safety components in gas-fueled machinery. They are designed to protect the exhaust system from catastrophic failure by venting over-pressure caused by an internal gas explosion. These systems ensure that the structural integrity of the exhaust manifold and piping is maintained during an accidental ignition of gas-air mixtures.

All Options

closable non-return valve system

single nonreturn valves system

two nonreturn valves system

Pressure relief systems (Correct Answer)

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Training for Ships subject to the IGF Code (AIGF).
