Q

The lowest temperature at which fuel oil gives off sufficient vapor to burn continuously when ignited is defined as the __________.

🔍 Key Concepts

• flash point vs. fire point definitions in marine firefighting • difference between auto ignition temperature and needing an external flame • how fuel behavior changes as temperature increases (vapor formation and continuous burning)

💭 Think About

• Ask yourself: at which stage does the fuel just begin to give off enough vapor that it can catch fire when exposed to a flame, even if it might not keep burning by itself? • Consider which term is used when the fuel will keep burning on its own once ignited, not just flare up and go out. • Think about which option requires no external flame at all because the fuel ignites just from being hot enough.

✅ Before You Answer

• Verify which term refers to the first temperature where vapors can be ignited by an external flame. • Verify which term refers to self-ignition without any spark or flame. • Verify which term specifically requires that the fuel burns continuously after ignition, not just momentarily.
