Four employee were pouring a 320" copper stock.  A hose failed which caused the ram of the casting unit to drop during the pouring process. The falling of this ram, which was controlled by the caster, allowed molten copper to come in contact with steam inside the pit that is filled with water. This caused a violent reaction/explosion. All four employees received burns to their arms, body, and face when they were sprayed with molten copper.
