Will flammable gas concentration above the upper explosive limit burn?
No, flammable gas concentrations above the upper explosive limit (UEL) are too rich to ignite and burn. In order for a flammable gas to ignite, it needs to be within its flammable range, which lies between the lower and upper explosive limits. Concentrations outside this range will not burn.
What is the upper limit of the stratosphere?
The upper limit of the stratosphere is typically considered to be around 50 kilometers (31 miles) above the Earth's surface. It extends from about 10 kilometers (6 miles) to the upper limit, where the stratopause marks the boundary with the mesosphere.
The properly posted explosive limit sogn requires the NET Explosive weight and?
The properly posted explosive limit sign must indicate the maximum allowable NET Explosive Weight for the designated area. This weight includes the total weight of explosives, detonators, and any other initiating devices present. The sign helps ensure safety by preventing the accumulation of a hazardous amount of explosives.
What is the lower explosive limit of hydrocarbon product?
The lower explosive limit (LEL) of a hydrocarbon product is the minimum concentration of vapor in the air that is needed to create an explosive mixture. It varies depending on the specific hydrocarbon product but typically falls between 1-5% of the air by volume. Operating within safe limits is crucial to prevent the risk of explosions.
Why is there a lower limit to temperature but not an upper limit?
lower limit because the particles have zero energy. there is no upper limit because particles can move as fast as they like. There is an upper limit on temperature, called "Planck Temperature". It is approximately 1.42e32 Kelvin! This temperature is the maximum temperature something can attain, with the physics we understand.
What are the six physical properties associated with hazard recognition of hazardous materials and chemicals?
vapor pressure evaporation rate flashpoint upper explosive limit lower explosive limit
Will flammable gas concentration above the upper explosive limit burn?
No, flammable gas concentrations above the upper explosive limit (UEL) are too rich to ignite and burn. In order for a flammable gas to ignite, it needs to be within its flammable range, which lies between the lower and upper explosive limits. Concentrations outside this range will not burn.
What is UEL?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
What is lel uel?
All of natural gas has LEL which means lower explosive limit and UEL upper explosive limits mean if lower or upper value for any gas found you get explosion.
What is the difference between LEL and UEL?
LEL is the Lower Explosive Limit. The lowest ignitable concentration of a substance in air that will ignite. UEL is the Upper Explosive Limit. The highest percentage of a substance in air that will ignite.
What is the Percentage range of lel and uel for natural gas?
The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air. The Upper Explosive Limit (UEL) is 15% by volume in air
What is the differrence between lel and uel?
LEL (Lower Explosive Limit) is the minimum concentration of a gas or vapor in air below which it will not ignite, while UEL (Upper Explosive Limit) is the maximum concentration above which it will not ignite. These limits are important for assessing the fire and explosion risks of gases and vapors in various settings.
What is lel?

What is the upper and lower limit of 20?
Twenty one is the upper limit and nineteen is the lower limit of twenty.
What shape has the most angles?
There is no upper limit to the number of angles you can have.
