What does LEL mean in OSHA?
Lower explosive limit
Lower explosive limit (LEL) means the minimum concentration of vapor in air below which propagation of a flame does not occur in the presence of an ignition source.

What is a safe LEL?
If a gas concentration is below its LEL, it cannot ignite, and the confined space is considered safe. If the gas concentration is above its UEL, the gas is too rich and there’s not enough oxygen for combustion. Of course, LEL and UEL differ for each gas. Methane, for example, has an LEL of 5% vol and a UEL of 15% vol.
What is a safe LEL level?
What is a safe LEL level? Factory default alarms are typically set very conservatively: Low 10%, High 20%. It’s important to understand that conditions can change suddenly, and that the LEL sensor isn’t able to discern what specific gas (or combination of gasses) is being measured.
What is LEL in hazmat?
The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with oxygen (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.
What is 100% LEL?
One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas.
What is LEL & UEL?
Lower explosive limit (LEL): the lowest concentration of gas or vapour which will burn or explode if ignited. Upper explosive limit (UEL): the highest concentration of gas or vapour which will burn or explode if ignited. From the LEL to the UEL, the mixture is explosive. Below the LEL, the mixture is too lean to burn.
What is the bump test?
A bump test is the only way to ensure the whole gas detector unit is working properly. It checks that the sensors respond to the target gas, it also verifies that the display reacts. It confirms that all the alarms are activated, and the detector goes properly into alarm.
What is 10% of the LEL?
LEL sensors measure percent of LEL. For example, Gasoline has an LEL of 1.4%. Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline.
What is the difference between volume and LEL?
Different combustible gases have different lower explosive limit concentrations. For instance, the LEL for methane (CH4) = 5.0% volume, while the LEL for propane (C3H8) = 2.1% volume. The lower explosive limit (100% LEL) concentration for hydrogen is about 4.0% volume, which is equal to 40,000 ppm.
What is the difference between LEL and LFL?
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 term is considered by many safety professionals to be the same as the lower explosive level (LEL).
What is LEL of LPG?
L.P.G., therefore, does not present an IDLH hazard at concentrations below its lower explosive limit (LEL). The chosen IDLH, based on the “estimated” LEL for L.P.G. (19,000 ppm), is the concentration above which only the “most protective” respirators are permitted.
What is LEL and PPM?
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.
What is LEL of natural gas?
Defining Lower Explosive Limits (LEL)
LEL stands for “Lower Explosive Limit” and is the lowest concentration of a particular gas that has the potential to be flammable or combustible. In other words, it’s the minimum amount of gas that will catch fire or explode when an ignition source is present.
What is LEL and UEL of LPG?
LEL : 1.8 % UEL : 12.8 % TDG FLAMMABILITY: FLASH POINT (°C): -76 AUTO IGNITION. Page 2. MSDS: LPG.
What is flammable range of LPG?
The lower flammability limit (LFL) is found to be 1.81% and upper flammability limit (UFL) is 8.86% of LPG for upward propagation of flame. Whereas, for downward propagation of flame, the LFL and UFL are 1.87 and 7.69% of LPG, respectively.
What is LEL and UEL of H2S?
Flammability Range. U.E.L. H2S = 46% or 460,000 ppm. L.E.L. H2S = 4.3% or 43,000 ppm. Below 4.3% = Too Lean to Burn.

Does LEL change with pressure?
Initial pressure has little effect on the LEL except at very low pressure (<50 mmHg absolute) where flames do not propagate, while UEL increases significantly as the initial pressure is increased, broadening the flammability range From Figure 2.5, there are nearly linear relation between the explosion pressure and the …
