If the concentration of the gas is below the LEL value, the mix between the gas itself and the air is too weak to spark.

That means the mixture is too lean to burn if there is less than 4% Hydrogen present. But at 4%, we can burn or explode if there is an ignition source. So 4% v/v Hydrogen is the same as 100% LEL of the explosive concentration. おばあちゃん お年玉 何歳まで
