[QUOTE="Caustic Burno, post: 1430451, member: 694"] Getting into a little organic chemistry gasoline consists of C4 to C12 hydrocarbons Diesel C12 to C20 this is not a real fine cut. The static is created by filling flash point has little to do with it. It is a spark created in the vapor mixture over the liquid. The flammability of a hydrocarbon vapor-air mixture depends on its vapor pressure, flash point and temperature. These properties are used to classify petroleum products whose electrical resistivities are high enough to enable them to accumulate significant electrostatic charges under certain handling conditions. Following are the three petroleum product Vapor Pressure Classifications, including common examples: Low – Those with a closed cup flash point above 100°F (38°C). These products do not develop flammable vapors under normal handling conditions. However, conditions for ignition may exist, if handled at temperatures above their flash points, are contaminated with higher vapor-pressure materials, or are transferred into containers where vapors are at concentrations at or above those necessary to produce a flammable mixture. Examples: #2 Fuel Oil; Kerosene, Diesel, Jet Fuel A (commercial), Motor Oil, Asphalt, and Safety Solvents Intermediate – Those with a closed-cup flash point below 100°F (38°C). These products may create a flammable mixture in the vapor space at ambient temperatures. After reading all that mumbo jumbo about Reid Vapor Pressure some of the same hydrocarbons in gasoline upper end are in diesel lower end. [/QUOTE]
