I know a farmer who lived to tell the tale. He had a bunch of empty sacks, and he had piled them up and was ready to burn them. He poured some gasoline on them so that the fire would start easily. Unfortunately, he didn’t know that one of the sacks contained a little bit of ammonium nitrate, which happily combined with the gasoline and fire. Next, the mixture exploded, throwing burning gasoline everywhere.
After he managed to put the fires out he was taken to the hospital. Today, he still has some nasty burn marks on his skin, but he survived.
