Local metal recycler has an electric arc furnace. Old fencing, bicycles, chunks of cars, whatever goes into the furnace to be melted.

A water heater, still filled with water, stuck to the side of the crucible. When most of the metal was flat-bath (all melted and liquid) the water heater fell loose into the 2000 degree pool.

The resulting explosion blew out the side of the furnace, raining shrapnel and droplets of steel on everything in a 20 foot radius. A man was standing there.

It took half a year for him to return to work, much scarred both physically and mentally. He still can't go back into the furnace room. They found other work for him in the yard and office.
