Bonding and grounding during fueling operations are focused on preventing static electricity from becoming a hazard. As fuel moves through hoses and fittings, friction and movement can build up a static charge on the vehicles, tanks, and equipment. If there’s a potential difference between these metal parts and the earth, a discharge can occur, and in an environment with flammable vapors, that discharge could ignite the fuel mixture. Bonding provides a continuous electrical connection between all metallic parts involved, while grounding drains any accumulated charge to the earth, keeping everyone and the equipment at the same electrical potential. This safety measure is not about changing fuel flow, measuring temperature, or supplying power; it specifically reduces ignition risk from static electricity.
