Common to all aviation facilities is some form of flammable or combustible liquid storage. How is this storage type determined? Is the storage provided adequate? How can we ensure that fire or other incident will be prevented? Where do we start when specifying, installing, or inspection liquid storage tanks? Guidance on liquid classification, tank types and installation, and fire/spill protection requirements is found in the National Fire Protection Association standard, NFPA 30, Flammable and Combustible Liquids Code.
The first step to determine the storage requirements of such liquids (typically fuel at aviation facilities, but also oils, chemicals, cleaning solutions or the like) is to clearly define the characteristics of the liquid. Defining the liquid answers these two questions:
- Is this liquid flammable or combustible?
- What class of liquid is this?
