What temperature can gasoline still give off flammable vapor?
The FR (flammable range) of gasoline is 1.4% LEL (lower exposive limit) to 7.6 UEL (upper exposive limit). Below 1.4% the gasoline vapor is said to be too lean and above 7.6% and the vapor is too rich. In either case gasoline will not burn if it is not in the FR.
What is upper explosive limit?
The highest concentration of gas in air is capable to producing flash of fire in presence of ignition source.
Why do gas companies mix a smelly gas with methane?
That's so you'll know you have a gas leak before the concentration of methane in the air reaches methane's lower explosive limit.
What is the lower explosive limit of hydrocarbon product?

What has to happen for a gas or vapor to be flammable or an explosion hazard?
For a gas or vapor to be flammable or an explosion hazard it must have a concentration in air between the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) for that particular gas or vapor.
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 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.
