WebMethane is explosive between its LEL of 5% by volume and its UEL of 15% by volume. Because methane concentrations within the landfill are typically 50% (much higher than its UEL), methane is unlikely to explode within the landfill boundaries. As methane migrates and is diluted, however, the methane gas mixture may be at explosive levels. WebToday, most meters use a methane base to measure the combustible gas spectrum. Therefore, gases with a hydrocarbon base, other than methane, require multiple factors applied to your Lower Explosive Limit (LEL) reading. Depending on the meter, this can range from approximately 0-5.0. For example, gasoline has a factor of 1.63.
