WebThe lower explosive limit is also known as the lower flammable limit or LFL. To give an example, propane can explode once it reaches 2.1% of the air, by volume. So, the LEL of propane is 2.1%. The LEL or lower explosive limit varies from one gas to another. In general, for most flammable gases LEL is less than 5% by volume.
