### What are LEL and UEL? How to Convert to PPM? KarfScoot

· % vol = 10 ppm % vol = 1 ppm. The % LEL value can be used with the gas name as each gas has its own variable LEL value. If we look it on the example of hydrogen sulfide, which is both toxic and flammable gas: 100% LEL = 4% vol = 40,000 ppm H 2 S 50% LEL = 2% vol = 20,000 ppm H 2 S 10% LEL = % vol = 4,000 ppm H 2 S.

### LEL and Other Combustible Gas Concentration Units | ChemDAQ

To convert from % LEL to ppm, it is necessary to know the Lower Explosive Limit. Using ethylene oxide (EtO) as an example, the LEL is 3% by volume, which is equal to 30,000 ppm. It is common therefore in facilities that use large amounts of EtO to have two different types of monitor. One set of monitors measures EtO at parts per million concentrations to warn about potentially toxic exposures

### LEL versus PPM – Esders GmbH

· Methane is also measured in ppm (parts per million). The LEL monitoring serves the safety of individuals, because it can be stated that 100% LEL corresponds to 100% risk of explosion. When working in an area above the LEL, an ignition source in combination with oxygen can cause an explosion. In Europe, we have set the LEL of methane at vol.%.
