🔍 Key Concepts

• flammable range of a fuel vapor-air mixture • difference between too rich and too lean to burn • conditions needed for explosion or fire (fuel, oxygen, ignition source)

💭 Think About

• What does it mean, in safety manuals, when vapors are said to be "within the flammable range"—does that imply they will definitely not burn, or that they are capable of burning? • Think about the terms "too rich" and "too lean"—which of these describes vapor concentrations that are outside the flammable range? • If a mixture is within the flammable range, what will happen if an ignition source (spark, hot surface, open flame) is introduced into that space?

✅ Before You Answer

• Review the definitions of lower explosive limit (LEL) and upper explosive limit (UEL) and what "between LEL and UEL" really means. • Confirm whether too rich or too lean mixtures fall outside the flammable range. • Ask yourself: In a compartment with vapors within the flammable range, would a safety manual require strict control of ignition sources? Why?
