What is the explosive range of ethanol?

The explosive range of ethanol is recognized to be between 3.0% and 19.0% when mixed with air. This percentage indicates the lower and upper limits of concentration in which ethanol can form an explosive mixture. When the concentration of ethanol in air falls below 3.0% or rises above 19.0%, it is no longer capable of sustaining combustion or explosion. Understanding this range is crucial for firefighting and safety measures because it helps identify the conditions under which ethanol can pose a fire risk. Proper knowledge of such explosive properties ensures that firefighters can effectively manage hazardous materials and maintain safety during incidents involving flammable substances.
