3.3. Flash Point
Flash point is widely used to assess hazard associated with a flammable liquid to determine its fire and explosion risk. It is defined as the minimum temperature needed for a material to start emitting sufficient vapor and form a flammable mixture with air (Crowl and Louvar, 2011; Engineers. Center for Chemical Process Safety, 1993; Lees, 2005; Moghaddam et al., 2012) at atmospheric conditions. For a liquid mixture consisting of a single flammable liquid with miscible nonflammable liquids, the flash point of the mixture occurs at a temperature where the partial pressure of the flammable liquid in the mixture is equal to the vapor pressure of the pure liquid at its flash point temperature. It is used to determine a chemical's ...
