LFL – Definition and Pronunciation

[ˌɛl ɛf ˈɛl]

What is LFL?

LFL stands for Lower Flammable Limit, also known as Lower Explosive Limit (LEL). It denotes the minimum concentration of a combustible gas or vapor in air below which combustion cannot occur due to insufficient fuel. LFL is critical in assessing fire and explosion hazards in industrial environments.

Examples of LFL

At the flammable concentration boundary, typically close to the Lower Flammable Limit (LFL) of the vapour air mixture, the gas cloud can ignite and, if unobstructed, burn back to the source pool as a «flash-fire».
