Figure 7 Grounding Above-Ground Storage Tanks
To avoid a spark from discharge of static electricity during flammable liquid filling operations,
a wire bond should be provided between the storage container and the container being filled,
unless a metallic path between the container is otherwise present.
Above-ground tanks used for storage of flammable liquids do not have to be grounded unless
they are on concrete or on nonconductive supports. Ground wires should be uninsulated so they
may be easily inspected for mechanical damage and should never be painted. Figure 7 illustrates
grounding above-ground storage tanks.
