🔍 Key Concepts

• Fire triangle: fuel, oxygen, and heat must all be present for a particular hazard to occur • Behavior of oil vapor (oil mist) inside a crankcase and what happens when it is ignited • Difference between a localized engine problem (like a cylinder not firing correctly) and a sudden, violent pressure event

💭 Think About

• Ask yourself: if you have oil vapor (fuel), oxygen, and hot spots (heat) all at the same time in a closed space, which type of event matches the fire triangle? • Which option describes a rapid, outward release of energy and pressure, and which options describe other engine performance issues? • Think about what normally happens in a crankcase versus inside a cylinder—where would misfire or dieseling occur compared with a pressure-related hazard?

✅ Before You Answer

• Verify which option describes a rapid pressure increase in a confined space filled with flammable vapor and air • Eliminate any answers that mainly describe abnormal combustion inside a cylinder, rather than in the crankcase • Confirm which term is associated with oil mist and hot spots in diesel engine crankcases in marine safety training materials
