Over 20 years ago there was a guy who built his own fireworks because his dad always had. He stuffed a 3" 3/8" wall pipe with blackpowder and lit it in front of his family. Shrapnel cut his wife in half and more shrapnel imbedded in the wall of a house down the road. Not sure what a safe distance is.
Isn't that called a "Pipe Bomb" ???
