section of this week's (11/20) edition. The articles on-line referenced some situations which may cause an explosion due to static discharge. One area of concern to modelers is listed here.

The article pertains to the plastic gas cans modelers often use
for the transportation and dispensing of gasoline for their aircraft:

"When filling a plastic container, the potential between the container and the fuel source (the nozzle and pump) isn't an issue; it's bonded via the fuel. However, a potential still exists between this container, and the vehicle.

"When filling into those little red plastic gas cans, a good way to
risk an explosion is to fill the can while it's resting in a plastic
truck bed liner. The cans themselves can develop some potential simply by being rubbed, or from air friction. Placing the can on the ground allows any potential between the can and the underlying surface, to dissipate, and reduces the explosion hazard (but does not eliminate it)."

While I am not sure how much "danger" is present, these are points one might want to consider. The posts can be found at:

and are titled "Airplane VS. Auto Fueling"

If the nozzle is put in contact with the container before the lid is opened then any potential difference will be earthed through the nozzle (this should also earth the entire vehicle too). I doubt there's really too much danger because cars build up a potential when they're being driven. Ever got out of a car and felt an electrical shock when your feet touch the ground? You've just earthed it
