However, atmospheres with flammable vapors below 10 percent of the LEL are not necessarily safe. Such atmospheres are too lean to burn.

How do you calculate LEL?

To compute the LEL of any gas in air, divide the unknown concentration by the LEL listed in the NFPA Handbook. 100% LEL’s for 9 of Gasco’s more common gasses are shown in the table to the left. For example, if you take 2.5% Methane in air and divide it by 100% LEL of methane (5%), the result is 50% LEL.

How is LEL calculated?

To compute the LEL of any gas in air, divide the unknown concentration by the LEL listed in the NFPA Handbook.
