🔍 Key Concepts

• Flash point and why it matters for safety in engine rooms • Typical temperature range of flash points for lube oils vs fuel oils • How lube oil temperature in operation compares to its flash point for a safe margin

💭 Think About

• Which option(s) are clearly too low because they would be unsafe in a hot engine room environment? • Which option(s) are so high that they may be more typical of very heavy oils or are unnecessarily high for common marine lube oils? • Think about the normal operating temperature of main engine lube oil and how far above that the flash point should be for safety.

✅ Before You Answer

• Eliminate any range that is close to or below typical engine-room ambient temperatures • Compare each range to typical lube oil operating temperatures (often around 140°F to 160°F or higher) and ensure the flash point is well above this • Remember that marine fuel oils and lube oils have different typical flash point requirements—do not confuse the two
