🔍 Key Concepts

• Flash point vs. auto-ignition temperature of lube oils • How hot surfaces (e.g., exhaust lines, turbochargers) can ignite or carbonize oil residues • Typical causes of engine-room fires involving lubricating and fuel oils

💭 Think About

• Think about what condition in the engine room could raise the oil temperature well beyond its normal operating range without an open flame. • Which option describes a situation known to cause oil to smoke, carbonize, or possibly ignite on contact? • Which choices are more about physical changes (like foaming or thickening) rather than directly creating a fire hazard?

✅ Before You Answer

• Ask which condition most directly raises the risk of ignition or heavy smoking of oil. • Eliminate options that mainly affect viscosity or foaming but not temperature to the point of ignition. • Consider where lube oil leaks in machinery spaces actually start smoking or burning in real-world incidents.
