WebOct 22, 2024 · The LEL (lower explosive level) of Hydrogen is generally considered to be 4% by volume (4% v/v). 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.
