WebFeb 3, 2024 · The concentration is all the same whether we use the %LEL scale, the percent scale or the ppm scale. 100% LEL = 5% methane = 50,000 ppm methane. 10% LEL = 0.5% methane = 5000 ppm methane. 1% LEL = 0.05% methane = 500 ppm methane. So here we have three numbers at the alarm level: 10 and 0.5 and 5000.
