LEL stands for which phrase?

Lower Explosive Limit denotes the minimum concentration of a flammable gas or vapor in air that can ignite if an ignition source is present. This defines the lower boundary of the flammable range; concentrations below this are too lean to burn. There is also an Upper Explosive Limit that marks the upper boundary of flammability. Gas detectors often report the reading as a percentage of the LEL, indicating how close the atmosphere is to the point where ignition is possible. The other phrases do not match this safety term: Lower Emission Level suggests emissions rather than ignition; Localized Explosion Limit and Least Energy Level are not standard terms used for explosive limits.
