Understanding Lower Explosive Limit (%LEL) - EGas Depot

Feb 14, 2018· Understanding Lower Explosive Limit (%LEL) The lower explosive limit (LEL) is the minimal amount of concentration needed of a particular chemical to cause an explosion. The LEL is determined empirically for each pure chemical and air mixture at a given temperature. If more than than one chemical is dispersed in the air, as is normally the case ...

LEL and Other Combustible Gas Concentration Units | ChemDAQ

We have absolute concentrations: mg/m3, relative concentrations: % ppm, ppb, and flammable concentrations: % LEL (Lower Explosive Limit) and probably some others I have not thought of. This article will explain the differences between these units and why people use one over another. A true concentration is the amount of gas present per unit volume.

Why LEL important in Gas Detection? - Inst Tools

Typical safety standards require that a gas detection unit give warnings at 10 – 20% of the LEL. Do not confuse the alarm level with the volume of gas required to reach the LEL. For example: Methane has an LEL of 5% by volume in air. For a gas detector to give an alarm at 10% of the LEL, it must trigger when it detects % by volume.

How to Convert LEL to PPM on a Gas Meter | Hunker

LEL stands for the Lower Explosive Limit of a gas. It is the minimal concentration of the gas required for the gas to ignite. It is normally expressed as a percentage of the total air. PPM stands for parts per million. It also is a measure of concentration, though it is often provided by gas meters.
