Battery relocation- Does anyone know of an actual hydrogen sulfide explosion incident?

I also had a battery explosion happen to me at a spray car wash. A guy asked for a jump start and he crossed the ends. Blew it up in my face. Had to find water for my eyes and an ER trip. Eye patches for the weekend and the worst part was a blown up battery in my 70 340 duster and a favorite mopar shirt with acid holes throughout. Kept my eyesight and i hookup the cables from then on.
