Storage tanks are widely used in the process industries to store liquids that are below their boiling point at atmospheric temperatures (some tanks may be insulated and they may have heating or cooling coils to adjust the temperature of the liquid that they are storing). Typically, the tank is either open to the atmosphere or to a system such as a flare or vent header that is at atmospheric pressure (this does not apply to floating roof tanks). Unlike pressure vessels, storage tanks cannot handle either high pressure or vacuum conditions.  

Broadly speaking, storage tanks fall into one of three categories: without a roof, with a fixed roof and with a floating roof. Tanks without a roof are unusual in the process industries because the contents are usually flammable or toxic and so must be contained. Also it is important that the liquid in the tank is not contaminated. However some tanks such as those for storing water may not need a roof.

The materials in this package provide information to do with the design and operation of storage tanks, including firefighting strategies.
