We do not work in refineries (or drive our campers there) where the risk of massive releases of gasoline could occur, but we do frequent gas stations where a large gasoline spill would cause this issue, provided, as quoted in the articles, the diesel was running at the time of the spill. I suspect a destroyed engine would be the least of our problems at that point.
For propane to cause this problem, the density of propane would have to be quite large to generate the density required to continue to run a diesel engine after you turned the key off. The smell alone would have alerted you to a problem long before a combustible concentration could have built up.
I have a Bachelor of Science in Chemistry from Villanova University; was a flight and ground safety officer for two Air Force Wings; trained at the University of Southern California in aircraft accident investigation; and investigated major aircraft accidents including loss of life and frame in the USA and overseas.
While my expertise is NOT (repeat NOT) in refinery safety, I am fully aware of aviation fuel safety and received training in major accident response at the Air Force On-Scene Commander school.

You're right; and this is why I do NOT run my engine while refueling at a service station with gasoline. But, have no such concern with running my refrigerator.
Impressive resume! I suspected as much...
BTW: the flammable range for gasoline is 1.4% - 7.6% in air at STP. Higher temperature widens the range. Higher pressure raises the range to higher values.

Engine overspeed is what took out the oil rig in the Gulf.

Yikes scary stuff, I,m going to drive with my engine off in future and never fill up at gas stations
Jokes aside it makes you think, for those with diesels like me, how many times I have waited in line, behind a gasser, to get to the solitary diesel pump with engine running. Then the chap in front is filling up with gas, has a mental moment and spills gas all over the floor in front of me! Turn engine off, no good, hit reverse, run like crazy. I guess some quick thinking would be required, grab fire extinguisher and smother the spill but my guess that woould be too late!
Any suggestions?

So, how do you run your refrig on propane when traveling? Just leave it on auto or switch to something else?

Ours, we just leave on auto never touch it, unless for example you go on a ferry and have to turn off the propane then we have to turn propane on, switch fridge to off for a few seconds then back to auto.
