During the transportation of fuel, a road tanker can become electrostatically charged. Before transferring fuel at a filling station, a safety bonding wire is connected between the tanker and the ground.
Explain how a fuel tanker can become electrically charged as it travels along a road.
Describe a major hazard associated with transferring highly flammable fuel to or from an electrically-charged tanker.
What type of electrical connection is made by using this safety bonding wire?
Explain how connecting this wire before transferring fuel reduces the risk of an accident.
