🔍 Key Concepts

• Flammable (explosive) range of a vapor in air • Typical lower explosive limit (LEL) and upper explosive limit (UEL) for common petroleum vapors such as gasoline • Which percentage range best matches "common fuel vapors" found in cargo tanks and bunkering operations

💭 Think About

• Think about what percent of vapor in air is needed before it can ignite at all – is it very close to 0%, somewhere in the middle, or very high? • Consider which range is most often cited in basic tanker safety training for gasoline or petroleum vapors in enclosed spaces. • Eliminate any ranges that are clearly too narrow or too wide compared with what you’ve heard about typical fuel vapor hazards.

✅ Before You Answer

• Verify that the chosen range starts above 0% (pure air cannot burn) and ends before the mixture becomes too rich to burn. • Check your memory of standard LEL/UEL values for gasoline or petroleum vapors – your answer should bracket those values. • Confirm that the span of the range (difference between low and high values) is reasonable for a practical explosive range, not unrealistically large or tiny.
