Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds ...
Any mixture of methane and air will therefore lie on the straight line between pure methane and pure air – this is shown as the blue air-line. The upper and lower flammability limits of methane in air are located on this line, as shown (labelled UEL and LEL, respectively). The stoichiometric combustion of methane is: CH 4 + 2O 2 → CO 2 + 2H ...

For each fuel, ignition occurs only within a certain range of concentration, known as the upper and lower flammability limits. For example, for methane and gasoline vapor, this range is 5-15% and 1.4-7.6% gas to air, respectively. An explosion can only occur when fuel concentration is within these limits [citation needed]
The limiting oxygen concentration is shown in the lower right of the diagram. The limiting oxygen concentration ( LOC ), [ 1 ] also known as the minimum oxygen concentration ( MOC ), [ 2 ] is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel.
Environmental regulators have found explosive levels of methane in a popular Berkeley park. Regulators and the city are sparring over the source of the gas and what to do about it.
The Interior Department on Monday proposed rules to limit methane leaks from oil and gas drilling on public lands, the latest action by the Biden administration to crack down on emissions of ...
European Union lawmakers on Wednesday adopted a law to place methane emission limits on Europe's oil and gas imports from 2030, pressuring international suppliers to clamp down on leaks of the ...
