FLAMMABILITY
Gases are the easiest substances to define in terms of flammability. For a gas/air mixture, if it is flammable at all, then there exists a lower limit of fuel concentration below which self-sustained burning does not occur. This is called the lower flammability or lower explosion limit (LFL or LEL). (LFL or LEL).
