04.02 What is the largest tank capacity that can be used?

Fuel storage volumes inside buildings can range up to over 100,000 gallons – as the main storage on the lowest level of the building.

Fuel storage volumes – above the lowest level of the building are highly restricted. Local building codes may limit the volumes to 50, 250, 550 or other restricted volume. The limitation may be on the tank size or the total volume in the room. The importance of the limitation is to limit the size of the generator day tanks.
