Transferring Flammable Liquids: Bonding & Grounding

Protect Yourself against static Electricity

Although almost impossible to avoid, static electricity can be controlled. The object is
to avoid creating an environment that promotes static electricity’s path, by presenting
a more attractive conductor for the charge to follow. Metal bonding and grounding
wires or cables are an effective control measure against electrostatic sparking. Wires
and cables provide a better conductive medium than air.

Below are some general guidelines and steps to safely transfer flammable liquids.


  • Bonding two conductive objects together results in the objects
    possessing the same electrical potential, negating the risk of static
    electricity. However, this potential can be different than the ground
  • When bonding, attach one clamp of the bonding wire to dispensing
    container and the other clamp to the receiving container. Ensure
    the connection is clean and metal-to-metal. for non-conductive
    containers utilize a grounding wire or rod inserted into container.


  • Grounding one or more conductive objects to the ground results in
    the object(s) possessing a electrical potential of zero.
  • When grounding attach a grounding wire to the copper grounding
    bar on the perimeter of the room, and the other end to the
    dispensing container, ensuring a metal-to-metal connection. Before
    proceeding, the operator should discharge any electrical potential
    they may have by making contact with the container or ground


  • Dispense liquids slowly and carefully, minimizing any splashing
    which could produce static electricity.
  • When finished dispensing, clean and return bonding and grounding
    equipment to the designated location.
