I"m always talking to another beekeeper and you hear those stories.
Just heard one the other day. A beekeeper had just put his bee-go on the fume board and layed them on the back of the trunk. Then lite his smoker and sat it on the back of the truck and went to the cab to get his tool and vail. He look back to see his whole back of the truck on fire.
Fumes and flames don't go togehter.
I didn't hear if he got his honey off that day.
