WebSep 20, 2024 · The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with oxygen (air). 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. WebAug 3, 2016 · The lower explosion limit of 1.9% is equivalent to a concentration of 23.3 gm/m3 so explosion is not a hazard. (The molecular weight of air approximates to 30 so a cubic metre of air weighs 1000 1230 ------- x30 =1230 gm so 1.9% represents a concentration of ------ x 1.9 24.4 100 = 23.3 gm/m3 ) port stephens cafe
