FC § 5705.3.2
Where differences of potential could be created, vessels containing flammable liquids, or combustible liquids at a temperature higher than 20°F (11°C) less than their flash points shall be electrically connected by bond wires, ground cables, piping or similar means to a static grounding system to maintain equipment at the same electrical potential to prevent sparking.
