Good discussion here: Grounding your vehicle while fueling???Question. Do any of the team's ground the car during fuel stops? I know F1 uses strips that stick up. I am sure someone one said an aerial buried that way car drives over and is grounded. Unsure about other types. In Australia the rules used to be.
- car must be stopped and turned off.
- occupants must exit the car.
- no one is allowed to touch the car other than to remove and replace fuel cap.
- all fueling must be done in designated fuel pit.
- refueling during a race was very rare. As they used to be short enough you could get through a section then refuel before the next section. Except the Kempsey Internation. We always needed a splash of fuel to make it and the time sure hurt.
However i think they now allow fueling in the pits. But all hot work must be done in a designated hot work area.
I agree most people I have seen are sloppy and spill fuel in the pits. I work in an aviation related industry, at work we had a helipad, two helicopters and a refueling trailer. the aircraft and the fueling trailer will built up static potential during fueling relative to each other and having a static line between the aircraft and the fueling trailer is very important, as it drains the charge as it's trying to build up. neither the aircraft or trailer are connected to earth ground at the helipad. having the two grounded to a common earth ground point will also work, since they are still connected to each other via the wires. however, when refueling aircraft in the field or remotely, there typically is no earth ground.I dont think stratic is the biggest issues. From the accidents I have seen its caused by spillage.
They say you should not talk on your cell phone while fueling your car, but how many stories have you heard of this being a problem compared to when someone spills fuel on a hot surface?
The issue is you do not want any static to try to jump between two ground points in vapor. As long as the static has an easy way to get to ground it will not try to jump. Just like me, I will walk down the creek to a bridge before I try and jump it. Static is just as lazy. Haha
All you need is the two points grounded to ground. So you can ground the fuel source to going and the vehicle to ground and all is good.
yup, it's an easy thing to do for safety.Don't kid yourself into thinking static electrical charge does not happen and cause fires. Been to plenty over the years. Easy to eliminate that issue but the unknowing don't know and most don't care because it won't happen to them...Until it does. Closing the loop between the fueling vessel and the item being fueled ends the static spark.
