Question 11

Question
Why is a fuel spill on an asphalt surface more damaging than a fuel spill on a concrete surface?
Answer
  • The vapors will spread faster on the asphalt surface
  • The asphalt surface will lose its color
  • The fuel will dissolve the asphalt surface
  • The asphalt will react to the fuel and spontaneously combust
