Protect you and your team from hazardous gases with this LEL gas chart. Stay informed and take action to prevent by relying on the LEL gas chart to keep you safe.

Download the Lower Explosive Limits (LEL) of Combustible Gases chart to see the ammonia LEL, hydrogen LEL, methane LEL, and more. The following are the lower explosive limits (LEL) of selected gases

The limits are commonly called the "Lower Explosive or Flammable Limit" (LEL/LFL) and the "Upper Explosive or Flammable Limit" (UEL/UFL). The lower and upper explosion concentration limits for some commonly used gases are indicated in the table below.

LEL UEL CHART BY GAS TYPE. Below is a table showcasing the LEL and UEL values for some major flammable gases, presented as percentages by volume in air. These values are crucial for understanding the explosive potential of these gases and ensuring safe handling in …

Nov 26, 2024 · LEL, short for Lower Explosive Limit, is defined as the lowest concentration (by percentage) of a gas or vapor in the air that is capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat).

for one gas group will automatically be certi˜ed for the less volatile gasses below it according to the chart. GROUP I. is concerned only with underground mining where methane and coal dust are present. GROUP II. gases occuring in surface industries, are sub-grouped according to their volatility. This enables electrical equipment to be designed

These conditions are defined as the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL). Any amount of gas between the two limits is explosive. It is important to note that each gas has its own LEL and UEL , as shown in the chart below.

Information about the Lower Explosive Limits (LEL) and Upper Explosive Limits (UEL) of a gas/vapor is very important. Below the LEL level, the fuel and oxygen mixture is very lean and it will not cause burning or explosion.

The following are the lower explosive limits (LEL) of selected gases: Hexane 1.1% vol Hydrogen 4.0% vol Isopropyl Alcohol (Isopropanol) 2.0% vol Methane 5.0% vol Methyl Alcohol (Methanol) 6.0% vol Methyl Ethyl Ketone 1.4% vol n-Pentane 1.4% vol Propane 2.1% vol Propylene 2.0% vol Styrene 0.9% vol Toluene 1.1% vol Xylene 1.1% vol
