WebBelow the explosive or flammable range the mixture is too lean to burn and above the upper explosive or flammable limit the mixture is too rich to burn. The limits are … WebThe temperature at which the vapors of a flammable liquid can ignite is known as the "flash point." A hazardous vapor concentration is present when a fuel vapor reaches a level known as the lower flammability limit (LFL) or lower explosive limit (LEL). These limits are usually expressed as a percentage by volume.
Safety Data Sheet: Natural Gas
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 (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot o… WebBoiling point: -60°C Melting point: -85°C Solubility in water, g/100ml at 20°C: 0.5 Relative vapour density (air = 1): 1.19 Flash point: Flammable gas Auto-ignition temperature: 270°C Explosive limits, vol% in air: 3.9-45.5 Vapour pressure, kPa at 20°C: 1880 Relative density (water = 1): 0.92 spring cloud sleuth zipkin como funciona
