WebHydrogen can be explosive at concentrations of 18.3% to 59%. Although this range is wide, it is important to remember that gasoline can present a greater danger than hydrogen because the potential for explosion occurs with gasoline at much lower concentrations: 1.1% to 3.3%.

WebWhat is the lower flammability limit of propane? A: The lower explosive limit (LEL) of a gas or a vapour, is the lowest concentration (in air) that is needed for the gas to ignite and explode. For example, propane can explode when it reaches 2.1 per cent of the air, by volume. At 2.1%v/v, propane has reached 100% of its lower explosive level. Weblarly uncertain.
