Undetectable Flammable Liquid

  1. Flammable Liquids Definition
  2. List Of Flammable Liquids
  3. Flammable Liquid Storage

First, the liquid itself is not flammable, but its vapors are. The temperature at which sufficient vapors are released is known as the flash point, a key concept. Although an in-depth discussion on flash point is outside the scope of this article, the flash point is a general indication of how likely ignition is. Please note that this video was made solely for demonstration purposes! Do not attempt to repeat the experiments shown in this video! So, in this episode, I’.


Flammable liquids are:

  • A liquid having a flash point of = 60.5° C (141° F)
  • Any material in a liquid phase with a flash point = 37.8° C (100° F) that is intentionally heated and offered for transport or transported at or above its flash point in bulk packaging.
