liquids stored in its facility. A flammable liquid is defined as one having a flash point below 100Â°F (37.8Â°C) with a vapor pressure not exceeding 40 psi (276 kPa). They are volatile in nature, constantly giving off heavier-than-air vapors that cannot be seen with the naked eye. Combustible liquids have a flash point at or above 100Â°F (37.8Â°C). When heated above their flash points, these liquids take on many of the characteristics of flammable liquids. One of the significant differences between flammable and combustible liquids has to do with the behavior of their vapors.
