Upper Flammability Limit (UFL)
The highest concentration of a vapor or gas that will produce a flash of fire when an ignition source is present. At concentrations higher than the UFL, the mixture is too rich to burn. It is often referred to as the Upper Explosive Limit (UEL).
Upper Flammability Limit (UFL) 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.
