In concentrations of 0-5% Methane in air, the mixture is too lean to ignite or burn. The relationship between percent LEL and percent by volume differs from gas to gas. These boundary lines are known as the upper and lower explosive limits.Join thousands receiving the latest content and insights on health and safety industry. From the health and safety perspective, the LEL concentration is considered to be Immediately Dangerous to Life or Health (IDLH), where a more stringent exposure limit does not exist for the flammable gas. It is normally expressed as a percentage of the total air. If the concentration of the gas is below the LEL value, the mix between the gas itself and the air is too weak to spark. This is important when ordering mixtures with no oxygen content; without oxygen, LEL is not a factor.ShopCross is a leading distributor of industrial maintenance and repair products, supplies, and equipment. LEL, short for “Lower Explosive Limit“, is defined as the lowest concentration (by percentage) of a gas or vapor in air that is capable of producing a flash of fire in presence of an ignition source (arc, flame, heat, etc.). (50% LEL methane x 5% = 2.5% volume).It’s also important to remember that in order to ignite and burn, a fire requires three elements: heat, fuel, and an oxidizing agent (usually oxygen). You will get an alert of a leak in the ducts before any gas or vapors have a chance to enter any work spaces and create health issues for employees. Zero percent Lower Explosive Limit (0% LEL) denotes a combustible gas-free atmosphere. The fire can be prevented or extinguished by removing any one of these elements. Lower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The lower explosive limit (LEL) is the lowest concentration of gas, fumes, or vapors required to produce fire in the presence of an ignition source like flame or heat. Looking for online definition of LEL or what LEL stands for? This means that it takes a relatively low concentration of gas or vapour to produce a … Learn whether a calibration station or docking station is best for maintaining your gas detection program. Once a gas reaches 100% of its LEL level, it is potentially combustible, and therefore unsafe. In gas-detection systems, the amount of gas present is specified as a percentage (%) of LEL. Generally, there is a minimum concentration of gas below which a flammable or combustible gas will not ignite and an upper concentration above which the air will be "too rich" to ignite. If you spend much time working with calibration gas, it’s very likely that you will see the term “LEL” used extensively. LEL, short for Lower Explosive Limit, is defined as the lowest concentration (by percentage) of a gas or vapor in air that is capable of producing a flash of fire in presence of an ignition source (arc, flame, heat). Backed by the industry leading technical expertise of Cross Company, ShopCross is your one-stop shop for everything industrial. The level of oxygen in fresh air is around 21% Volume. (2.5% ÷ 5% = 50%) The same theory can be applied to any of the gasses listed here.

Lel can have a subtle but significant difference from lol, as it can connote sarcastic or cynical laughter and can be used to laugh at someone. LEL stands for “lower explosive limit.” Basically a combustible gas will only ignite when it is within a specified range. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. The maximum concentration of a gas or vapor that will burn in air is defined as the Upper Explosive Limit (UEL). In other words, too much or too little gas will not ignite. One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas … An LEL Detector or LEL Meter detects dangerous levels of a combustible gas or solvent vapor in air, expressed in percent Lower Explosive Limit, or LEL.
