Lower Flammability Limit (LFL)

The concentration of a combustible material in air below which ignition will not occur. Mixtures below this limit are said to be "too lean". It is often referred to as the Lower Explosive Limit (LEL).

Lower Flammability Limit (LFL) concentrations are considered for endpoint distances during facility siting studies or consequence modeling conducted by aeSolutions' experienced modelers. Modeling helps companies identify the flammable and/or toxic consequences and impacts to receptors due to a chemical release.
