WebFlammability Natural gas has a limited range of flammability – in concentrations in air below 5 percent and above 15 percent natural gas will not burn. It also has a high temperature ignition of about 1,100 to 1,200 degrees … Lower flammability limit 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 … See more Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined … See more Gas and vapor Controlling gas and vapor concentrations outside the flammable limits is a major consideration in occupational safety and health. … See more In the U.S. the most common method of measuring LFLs and UFLs is ASTM E681.
