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.

This means that ethanol concentrations in enclosed spaces such as fuel storage and vehicle fuel tanks are flammable over the temperature range 13-42 °C. Thus, there are higher risks of fire and explosion than with diesel fuel, or even gasoline.

WebMar 28, 2011 · Pure ethanol has a flash point of only 55 degrees F. Add 15 percent water and the flashpoint rises to 68 degrees F. Ethanol is still flammable mixed with water. That means that if you had a spill involving a 100,000 gallon tanker you could dilute it with as much as 900,000 gallons of water and still have a fire hazard. WebJul 1, 2024 · Most flammable liquids with a flash point between 35 °C and 60 °C show sustained combustion as defined in UN test L.2. Only a minority of this group does not support combustion. Of the liquids that do not support combustion, most contain high amounts of components which do not burn, such as water.
WebAug 8, 2024 · Temperature Limits of Flammability (LTFL) – The temperature limit of flammability is the minimum temperature at which vapors in equilibrium with a liquid will be sufficiently concentrated to form flammable mixtures in an oxidizing atmosphere at atmospheric pressure. In theory, the lower temperature limit of flammability and the …
