Immediately after the first guy tumbled through the top of the Swepco Tube plant, his hero buddy jumped to follow him into the container, where a solution comprised of 40 to 70 per cent nitric acid awaited him. He stood waist-high in the liquid as he and three other men pulled their peer to safety. The victim was completely submerged in acid. He’s suffered burns from head to toe; his state is unknown, but other employees said they don’t think it’s enough to kill him. His saviour also sustained burns from the waist down and is in serious condition. Neither man has been identified, and OSHA is investigating.
