Propane overfill by a "professional"
Looks like I'll be shopping for a new local propane guy. Which I should have already done, but there's only one last straw. I took one of my 30# cylinders down to fill from dead empty. This genius ...

I don't understand the tanks blowing up. All the valves are designed to vent slowly. Tanks cannot blow up if the valves are operating properly.
We had a bad event close to me a few years ago at the local farm co-op. A customer brought a 100 lb.. cylinder to be filled. Within moments of starting the fill, the tank exploded, killing the young guy filling the tank. The shrapnel from the explosion ruptured a nearby bulk tank and nearly burned the building to the ground. A couple of others were also injured.
The cause of the tank exploding was later found to be that the cylinder had acetylene in it at some point and the acetylene residue combined with the introduction of propane caused a reaction.
