Q

Which defines the function of a spark arrestor?

🔍 Key Concepts

• Engine exhaust systems on gasoline and diesel engines • How sparks and hot carbon particles can ignite fuel vapors in the atmosphere • Difference between preventing sparks from entering a tank vs preventing sparks from leaving an exhaust

💭 Think About

• Is a spark arrestor placed at a tank opening or on an engine exhaust? Visualize where you have seen them installed on real vessels or outboard engines. • Which choice best matches the idea of stopping burning particles produced by the engine from reaching the outside air? • Which options are describing other safety devices (like bonding/grounding wires or ullage covers) rather than the specific role of a spark arrestor?

✅ Before You Answer

• Identify which choice talks about engine exhaust rather than tanks or static electricity. • Eliminate options that describe bonding/grounding systems or mechanical securing of covers, since those are different safety measures. • Confirm that the correct option matches the idea of containing sparks produced inside the engine so they don’t become an ignition source outside.
