Webflammability limit, and a potential liability — in a larger leak the expanding gas cloud is more likely to reach ignition sources. The wide flammability range of hydrogen-air mixtures compared to the other fuels is a disadvantage. For example, hydrogen can ignite when the mixture is 50% hydrogen (with air), whereas WebSep 20, 2024 · The range between the lower and the upper explosive limit (LEL / UEL %) is defined as the flammable range of a specific explosive and flammable gas. Examples of LEL for common gases: LEL for Hydrogen: 4.0 LEL for Methane: 5.0 The risk of explosion of combustible gases has to be managed carefully in any production site handling gases.
