WebThe lower explosive/flammability limit for both 70% ethanol (intended for drinking) and denatured alcohol is 3.3% by volume in air. When Charlie was sprayed on the Victim and visible flame was observed, the percent of denatured alcohol had to be between 3.3% and 19.0% by volume in air in the presence of an ignition source. WebJul 1, 2007 · For ethanol, the lower flammability limits (LFL) decreases from 3.7% for pure vapor to 3.2% with saturated water vapor. For acetonitrile, the decrease is from 4.2% to 3.8%. Thus, to a good approximation, the water vapor can be treated as an inert, enabling the data to be displayed on a single flammability triangle diagram. ...

WebE- diesel blends containing 10-15% ethanol have the vapor pressure and flammability limits of ethanol. 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. WebClass IB Flammable Liquid: Fl.P. below 73°F and BP at or above 100°F.

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.
