What is the flammable range of gasoline?

The flammable range of gasoline is indeed between 1.4% and 7.6% in the air. This range signifies the concentration of gasoline vapor in the air that can ignite and produce fire when an ignition source is present. If the concentration is below 1.4%, there is not enough fuel vapor for combustion, and if it is above 7.6%, the mixture is too rich in fuel and lacks sufficient oxygen to sustain a flame. Understanding this range is crucial for safety protocols, as it helps in assessing the hazards associated with gasoline spills or vapors in various environments.
