When I was in Civil War reenacting I knew a guy who had a very cavallier attitude toward black powder.
One morning before a battle, he was loading blank cartridges with a powder measure, dipping the powder out of a shallow pan. He was also smoking a cigar and flicking the ashes into the powder container.
When it flashed, it took all his hair and beard, both of which were quite long, gave him flash burns in both eyes and the resulting fire destroyed his tent with most of his gear.
Seems he had an open quart jar of gasoline inside the tent. He had used it that morning to start a campfire.
And people like this are allowed to breed!
