What does LEL stand for?

LEL stands for Lower Explosive Limit, which is the minimum concentration of a gas or vapor in the air that can ignite and cause an explosion when exposed to an ignition source. Understanding LEL is crucial in ensuring safety in environments where flammable gases or vapors are present, as it helps determine safe operational practices and conditions to prevent fires or explosions.

The concept of LEL is important for industries that handle flammable materials, as measurements below this limit indicate that the concentration of the substance is too low to ignite. Monitoring LEL levels allows operators to take necessary precautions, such as ventilation or control measures, to maintain safety in potentially hazardous environments.
