Here's a couple of posts I found on-line at "IPilot" in the Message
Board section of this week's (11/20) edition. The articles on-line
referenced some situations which may cause an explosion due to static discharge. Two areas of concern to modelers are listed.

"Recently I was reading about building a ventilation system for my basement woodworking shop. They stressed that if you use plastic tubing you have to run a ground wire down the tube to drain static buildup from the air friction inside the tube. They said the wood dust/air mixture can become explosive when ignited by a static spark."

This second 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"
( Note: a portion of the above post is also listed in RCU under
RC Fuels)
