He didn't tell me while I was doing it & there are no signs re this. Use of Mobys, yes, but not filling JCs.

Anyone know if he was talking bollocks or the truth?

I know this is a cold thread, 4bee, but I knew a guy who burned his Rangie to the ground doing just that - tailgate down, jerry's in the back. It's because the nozzle IS earthed that you can get a spark from the unearthed can. I've always fill mine, plastic or petrol, on the ground. Static builds from the movement of the vehicle, same as generating lightning in a cloud.

I think steel spikes in the forecourt might be overkill. Perhaps if you just drive a tent peg through the bottom of the jerry every time, that would be enough?

Static builds up from 2 different substances or materials rubbing together, like petroleum running through a pipe, or clothing rubbing on other materials. So your jerry can that has been moving around in the back will have created a static charge that is why you remove it and put it on the ground to get it to earths potential, also every time the petroleum is moved (poured) static is generated.

and you also earth it through your body when you pick it up......
and the nozzle touches the jerry as well as its filling to keep it earthed through the actual bowser.....



i have seen the big spikes with an earth at servos.....but i think its only on the lpg pumps.....

I wont repeat it but they do need to be on the ground and as Zook said its good practice to touch the car before you fill to earth the car. The biggest cause of petrol station fires is women because (when you could) they put the clip on so you dont need to hold the nozzle whilst filling and then go back to the car and sit in it the seat covers and the synthetic clothing they are wearing generates static then when they go back to take the nozzle out the static dishcarges and ignites the vapours. There is actually a video of exactly this happening at a servo in the US.

Mythbusters did test this sort of, they at first busted the myth that mobile phones can start a fire, they cant, but they then looked at what might do it that makes people think it was a phone and static was it.

The whole fear of jerry cans being filled on the ground due in part to the Rhino plastic ute liners many farm utes have, a big plastic surface like that generates a lot of static which is highly dangerous. I know of a few servos that wont let farmers fill up 44 gallon drums which are secured in the back of a ute with a plastic tub liner because of this. Matt
