At any gas station, there is a small risk of a gasoline fire caused by static electricity. To prevent static discharge during refueling, be sure to touch the vehicle with your bare hands as you exit the vehicle to clear any accumulated charge. If you re-enter the vehicle while refueling, you may accumulate a new charge; simply touch the vehicle body or other metal surface again, away from the refueling location, to discharge it. The discharge you feel (or “shock”) is a kind of protection.
Static electricity can also build up in portable containers carried in a vehicle. For this reason, only approved containers can be filled with gasoline, and these should always be removed from the vehicle and placed on the ground. This will “ground” the container and eliminate static build-up.
