Flamability limits for ethanol
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 The flammable/explosive limits of some gases and vapors are given below. Concentrations are given in percent by volume of air. See more In the U.S. the most common method of measuring LFLs and UFLs is ASTM E681. This standard test is required for HAZMAT Class 2 Gases and for determining refrigerant flammability classifications. This standard uses visual observations of flame propagation in 5 or … See more Combustion can vary in degree of violence. A deflagration is a propagation of a combustion zone at a velocity less than the speed of sound … See more Gas and vapor Controlling gas and vapor concentrations outside the flammable limits is a major consideration in occupational safety and health.
