I don't believe that a refrigerator on propane qualifies as an "open flame" device.
Cigars/cigarettes/flame throwers, campfires I believe would.
I have not heard of a gas station catch fire due to excessive vapors being ignited by the refer flame. Then again if the vapors are that thick and high I believe there are bigger problems of ignition from cars than from RV's. My TT sticks back 20+feet. I guess I could be super safe and pull over before I enter the gas station to turn it off and pull out and pull over to turn it back on.
