All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air. The Upper Explosive Limit (UEL) is 15% by volume in air
LEL (Lower Explosive Limit) is the minimum concentration of a gas or vapor in air below which it will not ignite, while UEL (Upper Explosive Limit) is the maximum concentration above which it will not ignite. These limits are important for assessing the fire and explosion risks of gases and vapors in various settings.
