Below the flash point, insufficient vapour is available to support combustion. At some temperature above the flash point, the liquid will …
WebDec 10, 2024 · Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. Combustible liquids have a flashpoint at or above 100°F. The vapor burns, not the liquid itself. The rate at which a liquid produces flammable vapors depends upon its vapor pressure. The vaporization rate increases as the temperature increases. WebIn assessing the risk of flammability, flash point analysis is an effective and efficient method. Essentially, the lower a substance’s flash point temperature, the higher its risk of flammability. By classifying materials according to this risk, this enables their correct and safe use and storage.
